Fractional CO2 laser versus combined platelet-rich plasma and fractional CO2 laser in treatment of acne scars: Image analysis system evaluation

A Network Meta-analysis to Explore the Effectiveness of the Different Treatment Modalities in Acne Scars

BACKGROUND

Multiple treatments are used to treat acne scars, but comparing the effectiveness of these treatments have not been studied yet. This research aimed to conduct a complete analysis of the effectiveness of commonly used therapies in acne scars.

METHODS

PubMed, Embase, and Cochrane's Library (Cochrane Center Register of Controlled Trials) databases were searched through May 2023. We used patient satisfaction score as the primary outcome and Goodman Baron qualitative scar grading system as the secondary outcome to evaluate the effectiveness of different commonly used therapies for acne scarring, including laser, microneedling (MN), platelet-rich plasma (PRP), autologous fat grafting and combined therapies.

RESULTS

Herein, 495 patients from 13 studies were included. Our results showed that PRP combined with laser was the most effective among therapies in treating acne scars. Ranking of effectiveness by the surface under the cumulative ranking (SUCRA) curve for patient satisfaction score was as following: PRP + laser (96.2%) > laser (71.2%) > MN (45.5%) > MN + PRP (42.0%) > autologous fat grafting (24.5%) > PRP (20.5%). Additionally, ranking of effectiveness by the SUCRA curve for Goodman Baron qualitative scar grading system was as following: PRP + laser (86.3%) > laser (64.2%) > MN + PRP (54.2%) > MN (37.2%) > PRP (8.1%).

CONCLUSION

This network meta-analysis indicated that the combined therapy of PRP and laser might be the most effective. Additionally, more high-quality randomized controlled trials are needed to verify our findings.

Effect of CO2 fractional laser combined with recombinant human epidermal growth factor gel on skin barrier

To evaluate the impact of CO2 fractional laser combined with recombinant human epidermal growth factor (rhEGF) gel on skin barrier in acne scar patients. In a retrospective analysis, we examined 105 acne scar patients admitted between July 2018 and August 2021. Of these, 51 received only CO2 fractional laser (control group), while 54 underwent a combination of CO2 fractional laser and rhEGF gel (observation group). We assessed treatment efficacy, symptom relief, skin barrier parameters, pre- and posttreatment inflammatory factors, adverse reactions, posttreatment quality of life, and patient satisfaction. The observation group exhibited a higher overall response rate, significantly shorter wound healing, scab formation, and scab detachment times. Additionally, this group showed increased stratum corneum water content, decreased pH, and transdermal water loss (TEWL), and reduced hypersensitive C-reactive protein and interleukin-6 expression posttreatment. Quality of life scores were higher, with fewer adverse reactions and greater treatment satisfaction. Combining CO2 fractional laser with rhEGF gel markedly improves acne scar treatment efficacy, enhances skin barrier function, reduces inflammation, and elevates quality of life. Its safety profile supports its broader clinical adoption.

Evaluation of combining ultrapulse CO2 with fractional CO2 laser for the treatment of atrophic scars in Asians

Various treatment modalities have been applied to atrophic scars. Fractional CO2 laser treatment has attracted increasingly more attention because of its quicker recovery time and fewer side effects. However, its limitation of sculpting the edge is an urgent shortcoming. In order to achieve a more effective result with fewer complications, we have integrated ultrapulse CO2 and fractional CO2 lasers to for the treatment of facial atrophic scars. The study included 25 patients (10 males and 15 females) diagnosed with moderate to severe atrophic scars between August 2020 and July 2022. All subjects underwent the same surgical treatment. The effects were assessed at baseline, 1 week, 1 month, and 3 months using photographic evidence. Objective evaluation of the results was conducted using a quartile grading scale, while the subjects' satisfaction and any adverse events were also recorded. The patients in the study underwent more than two laser sessions (2-5), resulting in substantial improvement in their appearance. The time interval between each session was 3-6 months. The majority of the patients (19/25, 76%) had a significant or even excellent improvement. Any adverse events observed, such as erythema, superficial crusting, and PIH, were of a mild nature and temporary in duration. This treatment combined two CO2 lasers is an effective and safe choice for atrophic scars in Asians.

Combining platelet rich plasma with ablative laser for post acne scars: A review

Background Acne scars are one of the most common sequelae of inflammatory acne. It commonly affects adolescents and young adults and hence is associated with significant psychological morbidity. It is historically resistant to oral as well as surgical modalities. In the last two decades, ablative lasers (fractional or otherwise) have proven to be effective in management of acne scars. Some studies have proven the efficacy of platelet rich plasma in reducing the adverse effects and improving the efficacy of lasers. Objective Review of the studies combining platelet rich plasma with ablative laser for post acne scars. Methods A literature review of the MEDLINE database for studies evaluating the combination of ablative lasers with platelet rich plasma was performed. Only studies with higher levels of evidence (randomised controlled trials and comparative studies) were included in this review. Results Adding intradermal platelet rich plasma to fractional ablative lasers in the management of post acne scars increases clinical efficacy, reduces downtime as well as frequency and duration of ablative lasers related adverse effects. The efficacy of topical platelet rich plasma is less as compared to intradermal platelet rich plasma. Limitations The studies analysed are heterogeneous in nature with varied protocols and duration of follow up. Conclusions It is recommended to combine the ablative lasers with intradermal platelet rich plasma for better clinical response and reduce adverse effects as well as downtime.

Fractional CO 2 Laser Combined With Autologous Nanofat Injection Versus Fractional CO 2 Laser Combined With Platelet-Rich Plasma in the Treatment of Atrophic Acne Scars: A Split-Face Comparative Study With Optical Skin Imaging

BACKGROUND

Atrophic acne scarring is a common problem. If left untreated, its implications can impair the quality of life. Various treatments, with differing degrees of success, are used to alleviate atrophic scars.

OBJECTIVE

To assess the efficacy of nanofat versus platelet-rich plasma (PRP) as an adjuvant therapy to fractional CO 2 laser (FCL) for atrophic acne scars.

METHODS

This study included 35 patients with atrophic acne scars who received 3 sessions of FCL at 1-month intervals on both sides of the face, followed by intradermal PRP injection on the left side. A single session of nanofat was injected into the right side of the face 2 weeks before the laser sessions. The evaluation was conducted 3 months after the final treatment session.

RESULTS

After treatment, the right side of the face showed a significant reduction in Goodman scores and the indentation index of the Antera camera. The left side showed a significant difference in Goodman scores, yet the Antera camera showed a nonsignificant improvement. Nonetheless, the difference between the 2 sides was statistically insignificant.

CONCLUSION

Atrophic acne scars improved with both modalities. As a result, cotreatment with these techniques may synergistically affect atrophic acne scars in efficacy and safety.

Therapeutic Efficacy of Bovine Basic Fibroblast Growth Factor Combined with Ultrapulsed Fractional CO2 Laser in Acne Scars: Randomized Controlled Trial

Objective

To observe the therapeutic efficacy of ultrapulsed fractional CO2 laser combined with bovine basic fibroblast growth factor (bFGF) on acne scars, so as to provide clinical evidence for future treatment of acne scars.

Methods

One hundred and twenty patients with acne scars admitted between October 2021 and August 2022 were selected as the research participants, of which 60 cases treated with bFGF plus ultrapulsed fractional CO2 laser were regarded as the research group (RG) and 60 cases with ultrapulsed fractional CO2 laser therapy alone were set as the control group (CG). The clinical efficacy, Échelle d'évaluation clinique des cicatrices d'acné (ECCA) score, and scar base depth before and after treatment were comparatively analyzed, and changes in skin pore value, texture value and skin barrier function were detected. Finally, the duration of redness, scabbing and erythema after treatment and the incidence of adverse reactions after treatment were counted.

Results

A higher overall response rate was determined in RG versus CG (P<0.05). Besides, RG was lower than CG in post-treatment ECCA score, scar base depth, skin pore value, texture value and transepidermal water loss (TEWL), and higher in skin water and epidermal oil content (P<0.05). Moreover, the duration of redness, scabbing and erythema was shorter and the incidence of adverse reactions was lower in RG than in CG after treatment (P<0.05).

Conclusion

The combination of bFGF and ultrapulsed fractional CO2 laser is highly effective and safe in the treatment of acne scars, which reserves widespread use in clinical practice.

Efficacy of fractional CO2 laser in combination with stromal vascular fraction (SVF) compared with fractional CO2 laser alone in the treatment of burn scars: a randomized controlled clinical trial

BACKGROUND

The appearance of skin scars is known as one of the main side effects of skin burns. Stromal vascular fraction (SVF), as a rich source of cell populations with tissue regeneration properties, plays an important role in the healing of skin lesions. Fractional CO2 lasers have occupied a special place in treating skin lesions, particularly skin scars, since their introduction. Our study aimed to compare the combination of SVF and fractional CO2 laser with fractional CO2 laser alone in the treatment of burn scars.

METHOD

This double-blind clinical trial study was conducted on ten patients with burn scars that were treated three times with a fractional CO2 laser at site of burn lesions, and one of the two areas studied was randomly injected with SVF. Two months after completion of the procedure, patients' scars were assessed using the Vancouver scar scale (VSS), biometric criteria, and physician and patient satisfaction ratings.

RESULTS

The results confirmed a significant improvement in VSS, cutometry, R7 criteria, complete density sonography, and skin density sonography in the fractional CO2 laser-treated group. The VSS criteria, epidermal thickness sonography, complete density sonography, and skin density sonography in the group treated with the combination of fractional CO2 laser and SVF also showed significant improvement. The VSS criteria and melanin index of Mexameter in the group treated with SVF in combination with fractional CO2 laser were significantly better than the group treated with fractional CO2 laser alone. Also, physician and patient satisfaction in the group treated with SVF injection in combination with fractional CO2 laser was significantly higher than the other group.

CONCLUSION

The results confirm the efficacy of SVF injection in combination with fractional CO2 laser in the treatment of burn scars and can be considered as a treatment option for better management of these lesions.

Efficacy of fractional CO2 laser therapy combined with hyaluronic acid dressing for treating facial atrophic acne scars: a systematic review and meta-analysis of randomized controlled trials

The present work aimed to systematically identify the efficacy and safety of fractional carbon dioxide (CO2) laser plus hyaluronic acid (HA) dressing in dealing with facial atrophic acne scars. Randomized controlled trials (RCTs) concerning fractional CO2 laser in combination with HA dressing for treating atrophic acne scars were screened in 8 electronic databases (containing PubMed, Embase, the Cochrane Library, Web of Science, China National Knowledge Internet, Wanfang, Sinomed as well as VIP). Besides, for the purpose of evaluating the risk of bias of the enrolled RCTs, the Cochrane Collaboration tool was adopted. Statistical analysis was completed using Revman5.3 software and Stata 14.0 software. Meanwhile, the quality of evidence was assessed by the GRADE system. Finally, 6 studies involving 623 patients were enrolled. According to the findings in this study, compared with fractional CO2 laser alone, fractional CO2 laser therapy combined with HA dressing reduced the scores of ECCA (échelle d'évaluation clinique des cicatrices d'acné) grading scale (MD=-3.37,95% CI [-5.03, -1.70], P<0.0001), shortened the time of crust formation (MD=-0.42,95% CI [-0.80, -0.04], P=0.03) and the time of crust removal(MD=-1.31,95% CI [-1.67, -0.95], P<0.00001), enhanced patient satisfaction (RR=1.85, 95% CI [1.44, 2.38], P<0.00001). All the reported adverse events including hyperpigmentation, erythema, edema, mild itching, and slight burning pain were controllable. In addition, fractional CO2 laser combined with HA dressing therapy had a lower incidence of hyperpigmentation than fractional CO2 laser alone (RR=0.37, 95% CI [0.23, 0.61], P<0.0001). The level of evidence for outcomes was classified to be low to moderate. According to our findings, fractional CO2 laser combined with HA dressing is efficacious and safe option for facial atrophic acne scars. Nevertheless, more high-quality trials are required for further verification in the future.

A Split Face Comparative Interventional Study to Evaluate the Efficacy of Fractional Carbon Dioxide Laser against Combined use of Fractional Carbon Dioxide Laser and Platelet-Rich Plasma in the Treatment of Acne Scars

Background

Fractional carbon dioxide laser (FCL) is an established treatment option for acne scars, but use of platelet-rich plasma (PRP) as an adjuvant still requires elaborate studies.

Aim

To compare the efficacy and safety of FCL alone and combined use of FCL with PRP in the treatment of acne scars.

Materials and Methods

This was a split-face (right-left) comparative study including 32 patients with moderate to severe acne scars. The patients underwent three sessions of FCL along with PRP and FCL alone on right and left sides of the face, respectively, at an interval of 6 weeks. Goodman and Baron qualitative and quantitative scores were used for the evaluation of results along with visual analog scale (VAS) for patient satisfaction and physician assessment of scars. Adverse effects following the procedure were also evaluated and compared.

Results

There was significant improvement of scars over both sides of the face, but the difference between right and left sides was not statistically significant according to Goodman and Baron qualitative (p 0.9115) and quantitative score (p 0.6957). On assessing VAS score, patients were more satisfied with the right side, but the values were not statistically significant (p 0.8571). Physician assessment grading showed comparable results over both the sides (p 1). There was no difference in adverse effects between both sides of the face.

Conclusions

Inclusion of intradermal PRP to FCL did not produce any statistically significant synergistic effects in the treatment of acne scars.

A Comparative Study on the Usefulness of Fractional CO2 and Fractional Er:YAG in Acne Scars: A Split-Face Trial

Background

Acne is a dermatologic condition with a high burden in terms of psychosocial consequences as a result of scars remaining on the skin. Its effects are severe in adolescence and finding treatments with short therapy courses, superior results, and fewer adverse effects are of high importance.

Materials and Methods

We included 30 individuals with acne vulgaris scars in Al-Zahra academic training hospital from June 2018 to Jan 2019. Each individual received both fractional CO₂ and fractional Er:YAG lasers on right and left sides of the face, respectively. Three sessions of laser treatment were applied to each side with one-month intervals. Results were evaluated by patients according to subjective satisfaction and physicians' assessment and photo evaluation by two blinded dermatologists. Improvement was graded by a quartile grading scale: less than 25%: mild, 25% to 50%: moderate, 51% to 75%: good, and 76% to 100%: excellent response. Assessments were obtained at baseline and one month after the last visit.

Results

Based on subjective satisfaction (p < 0.05) and physicians' assessment (p < 0.01), fractional CO₂ laser was significantly more effective than Erbium:YAG laser. Also, Post-treatment side effects were mild and transient in both groups.

Conclusion

Laser therapies are common in the treatment of scars and each modality has special advantages and disadvantages. Choosing among them should be based on various criteria. Fractional CO₂ lasers have been revealed favorable results in most reports. Large comprehensive trials could help experts in choosing among alternatives for different subgroups.

Safety and efficacy of CO2 dot matrix laser combined with platelet-rich plasma on depressed scar after acne vulgaris and influencing factors of its repair effect: A retrospective analysis

BACKGROUND

Acne vulgaris (AV) is the most pervasive inflammatory disease of hair follicle and sebaceous gland in the dermatology department, and depressed scar (DS) is the most common and serious sequela of AV.

AIMS

To explore the clinical value of CO₂ dot matrix laser combined with platelet-rich plasma (PRP)-treated AV.

METHODS

Total 81 patients with DS at the rear of AV from December 2018 to October 2019 were selected, randomly divided into observation group (OG, n = 39) and control group (CG, n = 42). Patients in the OG group were treated with CO₂ dot matrix laser combined with PRP, and those in the CG group were treated with CO₂ dot matrix laser. To observe clinical outcomes in both groups.

RESULTS

According to experimental analysis, compared with the CG group, CO₂ dot matrix laser combined with PRP can more strongly improve the clinical efficacy on patients, shorten the scar scabbing time and decrustation time, more effectively contributed to their scar repair, comfort, skin condition, psychological state and satisfaction, and reduced their pain. The subsequent follow-up results also showed that patients in the OG group experienced better quality of life. Moreover, according to the logistic regression analysis, the course of disease, scar degree, and staying up late were independent risk factors for the repair effect, and the repair method of CO₂ dot matrix laser combined with PRP was an independent protection factor.

CONCLUSION

To sum up, CO₂ dot matrix laser combined with PRP can strongly enhance the scar repair effect, psychological state, and life quality of patients with DS after AV, so it is worth popularizing in clinical practice.

Laser-Assisted Drug Delivery in the Treatment of Scars, Rhytids, and Melasma: A Comprehensive Review of the Literature

Although broad reviews on laser-assisted drug delivery (LADD) have been published in the past, an updated focused examination of its utility in the context of common, treatment-resistant, dermatologic conditions has not been published. This article reports a comprehensive scoping review of the potential benefits of LADD compared to laser or drug monotherapy for the treatment of 3 such conditions: scars, rhytids, and melasma. A PubMed (National Institutes of Health; Bethesda, MD) search was conducted for keywords including "laser-assisted drug delivery," "scar," "rhytid," and "melasma." Out-of-scope studies were excluded. To evaluate the efficacy of LADD for the treatment of scars, relevant articles were categorized by scar type: hypertrophic/keloid, atrophic, and hypopigmented. LADD, with both ablative and nonablative laser types, was studied in combination with corticosteroids, botulinum toxin-A (BTX-A), 5-fluorouracil, 5-aminolevulinic acid photodynamic therapy, stem cells, platelet-rich plasma, and prostaglandin analogs for the treatment of scars. Some randomized controlled trials demonstrated the efficacy of LADD, whereas others showed no significant differences in clinical outcomes but demonstrated reduced adverse effects. Regarding rhytids, laser treatment has been combined with various cosmeceuticals, including poly-L-lactic acid, topical retinaldehyde, and topical BTX-A. The studies reviewed supported the use of LADD with these drugs over monotherapy. Some studies showed that LADD was effective for the absorption of drugs such as poly-L-lactic acid and BTX-A which are often not effective topically. For melasma treatment, LADD with tranexamic acid and hydroquinone was superior in some studies, but not significantly different than monotherapy in other studies. LADD with certain drugs could be considered to treat scars, rhytids, and melasma.

Ablative fractional carbon dioxide laser combined with autologous platelet-rich plasma in the treatment of atrophic acne scars: A systematic review and meta-analysis

Atrophic acne scars are the most common cutaneous seqaule of acne vulgaris, representing 80%-90% of all acne scars. Ablative fractional carbon dioxide (FCO₂ ) laser is the gold standard treatment for atrophic scars. Additionally, platelet-rich plasma (PRP) is suggested to accelerate the healing process and collagen synthesis. The aim of the present systematic review and meta-analysis was to determine the efficacy and safety of PRP combined with Ablative FCO₂ laser in the treatment of moderate to severe atrophic acne scars. Randomized controlled trials (RCTs) that have compared PRP in combination with ablative FCO₂ laser to ablative FCO₂ laser alone with respect to the efficacy and safety measures were included. We have systematically explored Embase, Medline, and CENTRAL databases via Ovid. The outcomes that our systematic review sought to evaluate were clinical improvement, patient satisfaction, and Goodman and Baron's qualitative acne scar score. The dichotomous outcomes were presented as odds ratio (OR) while the continuous outcomes were presented as standardized mean difference (SMD). Eleven RCTs that represents 313 participants were included. The combined use of laser and PRP showed a statistically significant clinical improvement and patient satisfaction compared to the use of laser alone (OR = 2.56, 95% CI 1.37-4.78 and OR = 3.38, 95% CI 1.80-6.34, respectively). Also, a significant improvement in Goodman and Baron's score was achieved by combining PRP with laser (SMD = -0.40, 95% CI -0.65 to -0.14). The combined treatment of laser and PRP was highly synergistic, effective, and safe in treating moderate to severe atrophic acne scars.

Treatment of melasma with platelet-rich plasma: a self-controlled clinical trial

BACKGROUND

Melasma is a common circumscribed hypermelanosis of sun-exposed areas of the skin. Platelet-Rich Plasma therapy has been evidenced to inhibit melanin synthesis in animals and humans OBJECTIVE: To determine the effectiveness of platelet-rich plasma as a treatment for melasma.

MATERIALS AND METHODS

Twenty female patient with melasma were involved in this study. The intervention included three Platelet-Rich Plasma application sessions at 15-day intervals. Patients were evaluated before and after treatment. Variables measured included the facial melanin concentration using the Melasma Area and Severity Index score, Melasma Quality of Life Scale satisfaction grade, and histologic changes.

RESULTS

Mean age was 41±7 years. An initial MELASQOL score of 42±14.8 and final score of 16.6±7.2 (p = 0.008) were reported; the initial and final MASI score were 15.5±8.4 and 9.5±7.2 (p = 0.001), respectively. The dermatoscopy examination revealed a decrease in pigmentation after intervention (p=0.001). Histopathologic improvement was detected in reductions in cutaneous atrophy (14 [70%] vs. 11 [55%]), solar elastosis (15 [75%] vs.11 [55%]), and inflammatory infiltrate (9 [45%] vs. 6 [30%]), before and after treatment, respectively.

CONCLUSIONS

The intervention was associated with decreased intensity of the melasma patch and improved skin quality, shown by the MELASQOL and MASI scores. This article is protected by copyright. All rights reserved.

Platelet-rich plasma in the treatment of scars, to suggest or not to suggest? A systematic review and meta-analysis

Despite the rising trend for applying platelet-rich plasma (PRP) in the management of various types of scars, there is no convincing evidence supporting its use. This motivated us to review the randomized clinical trials that examine the effectiveness and safety of PRP, alone or in combination with other methods, for the management of atrophic or hypertrophic/keloidal scars. The Web of Science, Scopus, Google Scholar, and Cochrane Library databases were systematically searched until September 1^st , 2020. Thirteen clinical trials were enrolled in the meta-analysis, and 10 more were reviewed for their results. The random effect meta-analysis method was used to assess the effect size of each outcome for each treatment type, and I² was used to calculate the statistical heterogeneity between the studies. Patients treated with PRP experienced an overall response rate of 23%, comparable to the results seen with laser or micro-needling (22% and 23%, respectively) When used alone, moderate improvement was the most frequently observed degree of response with PRP (36%) whereas, when added to laser or micro-needling, most patients experienced marked (33%, 43%, respectively) or excellent (32% and 23%, respectively) results. Concerning the hypertrophic/keloid scars, the only study meeting the required criteria reported a better improvement and fewer adverse effects when PRP was added to the intralesional corticosteroids. Platelet-rich plasma appears to be a safe and effective treatment for various types of atrophic scars. In addition, when added to ablative lasers or micro-needling, it seems to considerably add to the efficacy of treatment and reduce the side effects.

Methods for the Improvement of Acne Scars Used in Dermatology and Cosmetology: A Review

Acne vulgaris is a chronic skin disease that, depending on its course, is characterized by the occurrence of various skin eruptions such as open and closed comedones, pustules, papules, and cysts. Incorrectly selected treatment or the presence of severe acne vulgaris can lead to the formation of atrophic scars. In this review, we summarize current knowledge on acne scars and methods for their improvement. There are three types of atrophic scars: icepick, rolling, and boxcar. They are of different depths and widths and have different cross-sections. Scars can combine to form clusters. If acne scars are located on the face, they can reduce the patient’s quality of life, leading to isolation and depression. There are multiple effective modalities to treat acne scars. Ablative lasers, radiofrequency, micro-needling, and pilings with trichloroacetic acid have very good treatment results. Contemporary dermatology and cosmetology use treatments that cause minimal side effects, so the patient can return to daily functioning shortly after treatment. Proper dermatological treatment and skincare, as well as the rapid implementation of cosmetological treatments, will certainly achieve satisfactory results in reducing atrophic scars.

Autologous platelet-rich plasma 'fluid' versus 'gel' form in combination with fractional CO2 laser in the treatment of atrophic acne scars: a split-face randomized clinical trial

BACKGROUND

The treatment of atrophic acne scars represents a therapeutic challenge. Recently, plasma gel has been introduced among treatment modalities.

OBJECTIVE

To compare the efficacy of platelet-rich-plasma 'fluid' versus 'gel' form combined with fractional CO₂ laser in the treatment of atrophic acne scars.

METHODS

Twenty-seven patients with atrophic acne scars were included. Treatment with fractional CO₂ laser plus plasma fluid/gel was randomly assigned to the right/left sides of the face. Clinical and Optical Coherence Tomography (OCT) assessments were scheduled at baseline, one month, and three months after the last session.

RESULTS

There was a significant improvement in clinical assessment scores at third-month follow-up on the plasma gel- and plasma fluid-treated sides compared to those at the first-month follow-up (p < .001). Scar depth decreased significantly at third-month follow-up when compared to baseline on both plasma gel- and plasma fluid-treated sides (p < .001). The numerical pain score was significantly lower on the plasma fluid-treated side compared to the plasma gel-treated side (p = .004).

CONCLUSION

The use of platelet-rich plasma in combination with fractional CO₂ laser, both in fluid and gel form, produced significant results in the treatment of atrophic acne scars. Patients reported an immediate more noticeable effect with plasma gel. However, the fluid injection was less painful.

A systematic review of evaluating the efficacy of acne scar treatment by Fractional Laser with or without using adjunctive treatments

Fractional laser (FL) resurfacing has proved its effectiveness in acne scars treatments. To evaluate the efficacy of Fractional laser systems for treatment of acne scars as a monotherapy, and as adjunctive therapy with other treatment types. A systematic literature review was performed by searching the electronic databases PubMed, Google Scholar, and Embase. Fractional laser has proven therapeutic efficacy of over 26% in treating acne scars, with minor and transient side effects, and well-tolerant pain. The application of PRP not only accelerated recovery and reduced adverse events, but also enhanced localized collagen neogenesis and redistribution. The addition of surgical treatments to Fractional Laser Systemes (FLS) therapy delivers the best treatment results for Icepick scars. Fractional laser is an effective tool for treating acne scars. The degree of effectiveness varies according to the laser parameters, the number of treatment sessions, skin photo type, the severity and the type of scars. The application of Platelet-Rich Plasma (PRP) and Fractional Radiofrequency Microneedle (FRM) in addition to the FL treatment improves the therapeutic efficacy and reduces the appearance of Post Inflammatory Hyper-Pigmentation (PIH), and is the ideal treatment for dark-skinned patients. FL therapy along with surgical methods such as subsicion and punch techniques provided the best improvements for deep scars.

Effect of Cognitive Behavior Oriented Psychological Intervention on the Psychological Status of Depressed Facial Acne Scar Patients Undergoing Fractional Photothermolysis

OBJECTIVE

To explore the effect of cognitive behavior oriented psychological intervention on the psychological status of depressed facial acne scar patients receiving fractional photothermolysis.

METHODS

The study enrolled 48 depressed facial acne scar patients who received treatment at our hospital between May 2018 and May 2021. They were randomized to the control group and the fractional photothermolysis group with 24 patients in each group using the random number table method. They received nursing intervention and cognitive behavior-oriented psychological intervention, respectively.

RESULTS

The Hamilton Anxiety and Hamilton Depression scores were lower after intervention than before intervention in both groups, and the fractional photothermolysis group had lower Hamilton Anxiety and Hamilton Depression scores than the control group (P < 0.05). The interpersonal sensitivity had hostility and phobic anxiety scores were lower after 12 weeks of treatment than before intervention in both groups, and the fractional photothermolysis group had lower interpersonal sensitivity hostility and phobic anxiety scores than the control group (P < 0.05). The H, M, V, and P scores after 12 weeks of intervention were both lower in the 2 groups than those before intervention. The humanistic care quality of service nursing care and health education scores were lower after intervention before intervention in both groups and the fractional photothermolysis group had significantly lower humanistic care quality of service nursing care and health education scores than the control group (P < 0.05).

CONCLUSIONS

Cognitive behavior-oriented psychological intervention can effectively improve the psychological status and psychological health of depressed facial acne scar patients receiving fractional photothermolysis.

Fractional Carbon Dioxide Laser or Erbium:Yttrium-Aluminum-Garnet Laser Assisted by Topical Application/Intradermal Injection of Platelet-Rich Plasma for Postacne Scars

BACKGROUND

Fractional carbon dioxide or erbium:yttrium-aluminum-garnet (YAG) laser combined with platelet-rich plasma has been used for postacne scars. Nevertheless, there is limited evidence on its use because of the small size of relevant studies. This study aims to evaluate the efficacy of platelet-rich plasma-assisted laser for postacne scars.

METHODS

Randomized controlled trials comparing carbon dioxide or erbium:YAG laser combined with platelet-rich plasma to laser alone were searched for using the PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar databases.

RESULTS

In total, 13 studies involving 672 cases were included. The overall degree of clinical improvement favored platelet-rich plasma combined with carbon dioxide laser (mean difference, 0.55; 95 percent CI, 0.40 to 0.70) or erbium:YAG laser (mean difference, 0.63; 95 percent CI, 0.31 to 0.96). Notably, the use of carbon dioxide laser combined with platelet-rich plasma was more effective in both greater than 50 percent improvement of acne scars (OR, 1.63; 95 percent CI, 1.10 to 2.42) and greater than 75 percent improvement of acne scars (OR, 2.78; 95 percent CI, 1.75 to 4.42), compared with laser alone. Erbium:YAG laser combined with platelet-rich plasma was more effective in greater than 75 percent improvement of acne scars compared with laser alone (OR, 3.45; 95 percent CI, 1.31 to 9.05). Moreover, patient satisfaction was significantly higher with platelet-rich plasma combined with carbon dioxide laser (OR, 2.98; 95 percent CI, 1.72 to 5.16) or erbium:YAG laser (OR, 2.88; 95 percent CI, 1.33 to 6.21) compared to laser alone.

CONCLUSION

This meta-analysis provides reliable evidence that fractional carbon dioxide or erbium:YAG laser combined with platelet-rich plasma is an effective and safe combination therapy for postacne scars.

Comparison of 1565-nm Nonablative Fractional Laser and 10600-nm Ablative Fractional Laser in the Treatment of Mild to Moderate Atrophic Acne Scars

BACKGROUND

The 10,600-nm ablative fractional laser (AFL) is widely used for treating facial atrophic acne scars but with evident side effects. By contrast, the common Er:Glass non-AFL (NAFL) is safer but lacks of comparable outcomes. A novel 1,565 nm Er:Glass NAFL improves thermal energy delivery and could yield better outcomes.

OBJECTIVE

We aimed to compare the effectiveness and safety between the 1,565-nm NAFL and 10,600-nm AFL in treating mild-to-moderate facial atrophic acne scars.

METHODS

Nineteen patients with mild-to-moderate bilateral facial atrophic acne scars were enrolled in a randomized split-face trial, which involved 3-session procedures for each laser. The effectiveness and safety were evaluated by doctors and patients who were blinded to the treatment assignment.

RESULTS

Both lasers improved the acne scar profiles comparably. A marked reduction in erythema, crusting durations, and degree of pain were noted on the sides treated with the 1,565-nm NAFL, relative to those treated with the 10,600-nm AFL.

CONCLUSION

Both 1,565 nm-NAFL and 10,600-nm AFL can improve mild-to-moderate acne scars. Patients should never expect complete resolution. The 1,565-nm NAFL has less side effects.

Rapid Wound Healing and Acne Scar Improvement After Ablative Fractional Carbon Dioxide Laser Treatment Combined with the Application of Platelet-Lyophilized Treatment (PLT)

Objective

There are several clinical cases on the application of PRP (platelet-rich plasma) therapies. To improve disadvantages such as the inability to be standardized and stored long term, we proposed a novel platelet-lyophilized treatment (PLT) to enhance the wound healing rate and improve acne scarring.

Study Design

A single-blinded study at a single health care center was performed. All subjects were treated with a fractional carbon dioxide laser. On the right side of the face, 2 mL PLT solution (dissolved in normal saline) was applied, while on the left side of the face (control group), 2 mL normal saline was applied. The treatment described above was repeated every 3 to 4 weeks, and 4 treatments were performed in total. Assessments were performed prior to each treatment and at the one-month follow-up after the fourth treatment. Subjective assessments included questionnaires administered by the principal investigator and a self-assessment questionnaire completed by the subjects. Moreover, VISIA complexion analysis was used for objective data collection, and spots, wrinkles, texture, pores, UV spots, brown spots, red areas, and porphyrins were objectively analyzed.

Results

Our data indicated that the PLT side showed a more rapid recovery than the saline side; on average, the sloughing off of the crusts was noted on day 5 and day 6. The improvement rate for skin spots, texture, and pores was significantly increased on the PLT side, with the pigment and pore size both having a statistically significant improvement of p<0.001, while the texture had a significant improvement of p<0.01.

Conclusion

The results suggested that the application of PLT could be a novel method to enhance wound healing and improve acne scarring after laser skin rejuvenation.

Fractional Carbon Dioxide Laser versus Combined Fractional Carbon Dioxide Laser with Platelet-rich Plasma in the Treatment of Atrophic Post-acne Scars: A Split-face Comparative Study

Context:

Though many treatment options are available for treating post-acne scars, optimized treatment still does not exist. Till date, comparative split-face studies, analyzing the efficacy of combined treatment modalities for acne scars with adequate sample size and with statistically significant results, are still lacking.

Aim:

The aim of this study was to compare the effectiveness of the combined use of platelet-rich plasma (PRP) and fractional ablative CO₂ laser (FACL) versus FACL in the management of acne scars and to study the safety of autologous PRP and FACL in the treatment of post-acne scars.

Settings and Design:

This was a randomized split-face trial study.

Materials and Methods:

This study was conducted in 30 patients having Goodman and Baron’s grade 3 and 4 acne scars. The efficacy of PRP in combination with FACL was compared to FACL alone in the treatment of post-acne scars. Right half of the patient’s face was taken as the study side where FACL was performed followed by PRP injections. The left half of the same patient’s face was taken as the control side where FACL was performed followed by normal saline injections.

Statistical Analysis:

Results were analyzed using Statistical Package for the Social Sciences (SPSS, Chicago).

Results:

At the time of enrollment, mean Goodman and Baron Acne Qualitative Grading Scale on study and control side was 3.80 with standard deviation (SD) of 0.40 at baseline. After completion of four treatment sessions, it was reduced to 2.43 (SD = 0.76) and 2.76 (SD = 0.49) on the study and control side, respectively. Improvement on both sides was statistically significant (P = 0.000).

Conclusion:

There is no single proven modality for the effective treatment of post-acne scars. Combination of FACL with newer adjuvants such as PRP has definitive role in managing post-acne scars with better safety profile than FACL alone.

Platelet-Rich Plasma: Evolving Role in Plastic Surgery

BACKGROUND

The use of platelet-rich plasma has emerged as one of the most desired nonsurgical treatments for facial rejuvenation and hair restoration. It has grown to encompass a wide variety of applications within the field of plastic surgery, including its use in combination with microneedling, laser, and fat-grafting procedures.

METHODS

In this article, the authors aim to (1) describe the preparation process of platelet-rich plasma; (2) discuss the proposed science behind platelet-rich plasma with regard to its evolving role in hair restoration and facial rejuvenation; and (3) highlight the recent literature examining its widespread use.

RESULTS

Based on the available literature, there is a therapeutic advantage to the use of platelet-rich plasma as a single treatment modality for alopecia and skin rejuvenation and in combination with laser skin treatment and fat grafting. There is, however, a considerable amount of variability in the processing, preparation, and treatment modalities.

CONCLUSIONS

Despite a lack of standardized protocols for platelet-rich plasma preparation and a scarcity of large-scale studies with long-term follow-up, there is convincing evidence with objective measurement modalities that display positive outcomes after treatment for skin rejuvenation, hair regrowth, wound healing, and fat graft take.

Use of Intra-uterine Injection of Platelet-rich Plasma (PRP) for Endometrial Receptivity and Thickness: a Literature Review of the Mechanisms of Action

Endometrial receptivity and thickness play an important role in achieving a pregnancy. Intrauterine autologous platelet-rich plasma (PRP) infusion has been used in infertile women with recurrent implantation failure (RIF) and thin endometrial lining thickness (EMT). Literature search was performed in PubMed for studies including in vitro, animal, and human studies as well as in abstracts presented at national conferences. Animal studies demonstrated a decrease in the expression of inflammatory markers and fibrosis, and increased endometrial proliferation rate, increased expression of proliferative genes, and increased pregnancy rates. The in vitro studies showed that PRP was associated with increased stromal and mesenchymal cell proliferation, increased expression of regenerative enzymes, and enhancement in cell migration. In infertile women undergoing assisted reproductive technology, one randomized clinical trial showed that PRP intrauterine infusion improved EMT, implantation rate, and clinical pregnancy rate (CPR) in patients with thin EMT, while 3 other trials involving subjects with RIF showed conflicting results related to CPR. Case series and cohort studies showed conflicting results pertaining to CPR. Data to date suggest that PRP may be beneficial in improving endometrial thickness and endometrial receptivity. However, further large prospective and high-quality trials are needed to assert its effect and to identify the population of patients that would benefit the most.

Theory and Evidence for Platelet Therapy of the Aging Face

Platelet preparations are autologous blood concentrates with supraphysiologic concentrations of platelets with or without leukocytes used in various clinical applications including regenerative medicine, wound healing, and facial rejuvenation. Their use harnesses the important role of platelets and their secretory products in immunoregulation, wound healing, angiogenesis, and tissue remodeling. The use of platelet preparations has been long documented in orthopaedic surgery, maxillofacial surgery, and other fields, but over the years research has increased in their application to facial plastic surgical techniques. Here we review the various formulations of platelet rich concentrates, their applications to facial skin rejuvenation, wound healing, scar reduction, and tissue fill as documented in the literature since 2018.

Synergistic effect of platelet-rich plasma in combination with fractional carbon dioxide laser versus its combination with pulsed dye laser in striae distensae: A comparative study

BACKGROUND

Striae distensae (SD) are very common atrophic cutaneous scarring that are therapeutically challenging. Various kinds of laser had been suggested as effective treatment modalities for SD. In addition, platelet-rich plasma (PRP) was recently recommended for its therapy.

OBJECTIVE

To evaluate the synergistic role of PRP injection as a combined modality to fractional CO₂ laser (Fr CO₂ ) versus its combination with pulsed dye laser (PDL) in SD.

PATIENTS AND METHODS

Thirty SD patients were included in this study and treated by intradermal injection of autologous PRP on both sides, followed by laser therapy (Fr CO₂ laser on right side and PDL on left side). They received 3 treatment sessions at 6 weeks interval.

RESULTS

Both treatment sides reported significant clinical improvements of SD lesions, evidenced by significant reduction of width of striae lesions and significant improvement of skin texture. Furthermore, significantly higher degree of clinical improvements were observed in response to treatment sessions by combined PRP with Fr CO₂ laser rather than combined PRP with PDL. Generally, post-inflammatory hyperpigmentation (PIH) were mild in all patients. Histopathologically, SD lesions showed improvement of epidermal thickness, and more homogenization and regular orientation of dermal collagen fibers in both treatment sides, with more significant improvement on the side treated by combined PRP with Fr CO₂ laser sessions rather than the other side.

CONCLUSIONS

PRP injection in combination with Fr CO₂ laser or PDL is considered safe and effective therapeutic regimens for SD. However, its combination with Fr CO₂ laser is more promising with better outcome and fewer side effects.

Identifying and appraising patient-reported outcome measures on treatment satisfaction in acne: a systematic review

BACKGROUND

After dermatitis, acne is the next skin disease to contribute most to the burden of skin diseases worldwide. Recently, seven core outcome domains have been identified, which together form an Acne Core Outcome Set (ACORN). One of these was satisfaction with acne treatment.

OBJECTIVES

To identify studies that described the development of patient-reported outcome measures (PROMS), evaluated one or more measurement properties of a PROM, or evaluated the interpretability of a PROM in patients with acne regarding treatment satisfaction.

METHODS

The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) search strategy for identifying PROMS on acne treatment satisfaction was used. We searched PubMed, MEDLINE, Embase, LILACS, Web of Science, Cochrane Library, Emcare, PsycINFO and Academic Search premier (June 2020). Study selection, data extraction and assessment of methodological quality according to COSMIN guidance were carried out independently by two authors.

RESULTS

Only one study could be included, describing the development of a treatment satisfaction measure in patients with acne. The development was assessed as inadequate and data on measurement properties were lacking. Additionally, we found 188 studies reporting treatment satisfaction solely as an outcome, using a wide variety of methods, none of them standardized or validated.

CONCLUSIONS

We could not find a PROM on treatment satisfaction to recommend for a core outcome set in acne. There is an unmet need for a PROM on treatment satisfaction in acne that is robustly developed, designed and validated.

Fractional carbon dioxide laser-assisted delivery of lyophilized-growth factors is a promising treatment modality of post-acne scars

Lyophilized-growth factors (L-GFs), is a new platelet rich plasma (PRP) preparation that is standardized in growth factors concentrations. The aim of this study was to compare the therapeutic efficacy of ablative fractional CO₂ laser in combination with L-GFs vs PRP in post-acne scars. This study was conducted on 45 patients presented with facial post-acne scars. Each patient received three sessions of fractional CO₂ laser on both sides of the face followed by topical application of L-GFs on one side and conventional PRP on the other side. Assessment was done before and after treatment semiquantitatively by Echella d'Èvaluation Clinique des Cicatrices d'Acné (ECCA) score and qualitatively by Goodman and Baron's qualitative scar (GBQS) scale, in addition to dermoscopic evaluation. The current study reported significant clinical improvement of post-acne scars on both sides of the face evidenced by significant reduction of both ECCA score and GBQS scale with minimal side effects. The degree of clinical improvement and patients' satisfaction were significantly higher with shorter downtime in response to fractional CO₂ laser combined with L-GFs rather than its combination with PRP. In conclusion, laser assisted delivery of L-GFs via fractional CO₂ laser could be considered a novel successful therapeutic modality for post-acne scars.

Effectiveness and safety of 2940-nm multifractional Er: YAG laser on acne scars

Erbium: Yttrium-aluminum-garnet laser (Er: YAG) treatment has been used in resurfacing the acne scars for a long time; however, we could not find any study reporting the recovery rates after each session of the treatment. In this study, we aimed to report the improvement rates after each session. We retrospectively analyzed the data of 35 patients with acne scars treated with fractional ablative Er: YAG laser. The patients received one to four sessions of treatment with 4-week intervals and improvement rates were recorded after each session. Data are available on request from the authors. The improvement rate of the lesions varied between 1% and 25% in 34 patients at the end of the first session, while in one patient, the improvement rate was detected as 26% to 50%. At the end of the fourth session, the rate of improvement was 26% to 50% in 14 out of 24 patients and 51% to 75% in 10 patients. None of the patients showed a 76% to 100% improvement at the end of the fourth session, whereas 48.6% of the patients were satisfied with the treatment. In patients with a high expectation of an excellent improvement, a higher number of sessions of the laser treatment and/or combination treatments with different treatment methods should be planned.

A meta-analysis of fractional CO2 laser combined with PRP in the treatment of acne scar

This study aimed to analyze the effectiveness and safety of ablative fractional carbon dioxide laser systems (CO₂ AFL) combined with autologous platelet-rich plasma (PRP) in the treatment of acne scars through the retrieval and collection of related literature to further guide the treatment of acne scars. We searched Web of Science, PubMed, Embase, Wanfang Data, Chinese National Knowledge Infrastructure, and VIP Database. All randomized and nonrandomized controlled trials on CO₂ AFL combined with PRP in the treatment of acne scars were included, and Revman5.3 systematic review software was used in the meta-analysis. Nine studies were included in this meta-analysis. The data analysis results showed that the CO₂ AFL combined with PRP treatment group showed significantly better results than the pure CO₂ AFL control group in terms of clinical improvement score, clinical improvement rate, patient satisfaction, and crusting period. The results of this meta-analysis showed that CO₂ AFL combined with PRP in the treatment of acne scars is more effective and safer than CO₂ AFL alone.
