Abstract
Background and Aims Acne vulgaris remains one of the most common and problematic dermatological conditions. Recently, a fractional 1927 nm thulium laser has been developed with specific water absorption characteristics which may be of interest in the treatment of acne. Subjects and Methods Nine consecutive Korean subjects, 6 females and 3 males, ages ranging from 13 to 33 yr, presented with a mixture of inflammatory and noninflammatory acne. Baseline clinical photography, image analysis and lesion counts were performed. A fractional 1927 nm thulium laser (FTL) delivered 6 treatment sessions in 5 subjects and 5 sessions in 4 subjects, 4 weeks between sessions. Pain during treatment was assessed. At 32 weeks after the last treatment session, an independent Investigator Global Assessment (IGA) performed lesion counts and graded the severity of the acne at baseline and the final assessment on a quintile scale. Data were analyzed statistically. Results All 9 subjects completed the study with significant reductions in the inflammatory and noninflammatory lesions (P values 0.0012 and 0.0081, respectively) with overall lesion counts at the final assessment ranging from 60% to 97.1%, and acne grades in the IGA dropping by an average of 1.67 (range 1 to 3 grades). There was no significant difference in lesion counts or acne grades between the subjects who had 6 treatments and those who had 5 (P = 0.7695). Mild pain was reported during treatment, and no adverse events were reported by either the subjects or investigator. Conclusions The FTL at the parameters used in the present study caused disruption to the upper portion of the affected follicles and sebaceous glands under an intact stratum corneum, thereby destroying or damaging the causative Cutibacterium acnes. The superficial controlled coagulation additionally induced follicular remodeling and tissue regeneration, potentially contributing to the noticeable results in inflammatory and noninflammatory acne lesions.

Abstract
Post-acne erythema (PAE) is a bothering skin condition that emerges from inflammatory acne and persists after its resolution. It is characterized by telangiectasia and erythematous macules. the role of 1064-nm Nd: YAG when combined with low-dose isotretinoin in the acne erythema treatment. forty-eight PAE patients were involved in the study. They were divided into two groups; group (A) patients administering a low dose of oral isotretinoin (10 mg/day) and underwent a total of six two-week interval sessions of 1064 ND-YAG laser treatment, group (B) patients administering a low dose of oral isotretinoin (10 mg/day) only. All adverse effects experienced during the course of therapy were documented, and photos were taken before the start of the treatment and following the end of the treatment duration. Following the completion of the therapeutic intervention, a significant improvement in clinical condition was observed in both groups, with more improvement in group (A) compared to group (B) as evidenced by a notable improvement in the score on the Clinician Erythema Assessment Scale (CEAS) and also a significant decrease in the mean value of optical density of the erythema. combined 1064-nm Nd: YAG with low-dose isotretinoin may be an efficient and secure line in the PAE treatment. Also, the combined therapy had superior results when compared to low-dose isotretinoin alone.

Abstract
Acne vulgaris is challenging to treat for several individuals. Laser therapy may be a desirable alternative to traditional therapies with limited success. This study aimed to assess efficacy of fractional CO2 laser versus Nd:YAG laser for acne vulgaris therapy. Thirty cases with acne vulgaris underwent both fractional CO2 laser and Nd: YAG laser treatments in a randomized split face design at a 14-day interval for four sessions. The clinical efficacy was evaluated by counting acne lesions and utilizing the Global Acne Severity Scale (GEA Scale). GEAs decreased significantly after both fractional CO2 and Nd:YAG modalities after treatment and at a 3-month follow-up; fractional CO2 demonstrated significant more decrease in GEAs with (P = 0.006, 0.00 (respectively. Moreover, fractional CO2 showed a significantly higher satisfaction level (P = 0.004) and a better clinical improvement percentage regarding inflammatory and noninflammatory acne lesions (P = 0.007 and 0.000, respectively) after 3 months of follow-up. Apart from transient erythema, there were insignificant adverse effects concerning both treated sides. Fractional CO2 and Nd:YAG lasers are efficient physical modalities of acne treatment. However, fractional CO2 laser was more effective and more satisfying to the patients.

Abstract
Purpose Post-acne erythema (PAE) is one of the most common physical sequelae of acne regression, PAE can resolve spontaneously, but in some patients it may last for years. This study aimed to evaluate the efficacy and safety of narrow and broad spectrum filters of intense pulsed light (IPL) for the treatment of PAE. Patients and Methods This prospective study evaluated 60 patients with PAE for at least 6 months, assigned equally to three groups: 1st group received narrow-spectrum with vascular filter (530-650 nm and 900-1200 nm), 2nd group received broad-spectrum with (560/590-1200 nm) filters, the appropriate adjustments were made according to patient's skin colour. Every patient received four sessions one month apart. 3rd group is blank control group did not receive any treatment. CAT (CEA (Clinical Erythema Assessment), Area, and Telangiectasia) used to grade clearance of PAE before and after treatment, Investigators Global Assessment (IGA) used to assess the improvement score after the treatment, and Cardiff Acne Disability Index (CADI) used to evaluate the impact of PAE on patients' Quality of Life (QoL). Self-satisfaction scale completed at the follow-up. Adverse events and acne relapse were recorded. Results A significant decrease of CAT score in vascular group (P<0.05). IGA scale showed significant improvement after vascular treatment. A significant decrease in CADI (P<0.05) after vascular treatment. Patient satisfaction was higher in vascular group than control and blank control groups. Acne relapse observed in control and blank control groups (40% and 15%, respectively).10% of patients showed pigmentation, 15% had blisters after 590 nm treatment. Conclusion IPL vascular filter (530-650 nm and 900-1200 nm) have efficacy in the treatment of PAE. CADI score, patient satisfaction, and acne relapse were significantly better after vascular narrow spectrum treatment than broad-spectrum treatment.

Hyperspectral assessment of acne skin exposed to intense pulsed light (IPL) intense pulsed light in acne treatment. Skin Res Technol 2023; 29:e13338. [PMID: 37357661 PMCID: PMC10209844 DOI: 10.1111/srt.13338] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 04/17/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND The mechanism of intense pulsed light action on the skin is based on selective photothermolysis. The light delivered to the tissue is scattered and absorbed by chromophores that absorb a beam of radiation of a specific length. The skin reflectance changes depending on the physiological state of the tissue, as shown by the hyperspectral camera. The aim of the study was to assess the hyperspectral reflectance of acne skin before and after intense pulsed light (IPL) therapy and to compare it with the reflectance of healthy skin. MATERIALS AND METHODS The study involved 27 volunteers with diagnosed moderate acne. The control group consisted of 20 people without acne lesions. All acne volunteers underwent a series of four treatments using IPL at weekly intervals. The volunteers with acne lesions were photographed before the series of treatments and a week after the 4th treatment. RESULTS Acne skin shows lower reflectance than healthy skin. Acne skin after IPL therapy is characterized by a higher reflectance compared to acne skin before the therapy and resembles the reflectance of the skin of the control group. A statistically significant difference was found between the acne skin before the treatments and the skin of the control group. CONCLUSIONS The effect of IPL therapy on acne skin is the increase of its reflectance by reducing the number of chromophores, which brings it closer to the reflectance value of healthy skin. Hyperspectral imaging allows for: the evaluation of the treated skin at each stage, a precise selection of the light wavelength depending on the problem, and therefore, for optimizing the number of irradiations and increasing the safety of the therapy.

Abstract
BACKGROUND Acne can be considered more than a cosmetic concern due to its large impact on patients' quality of life. There are various therapeutic options for inflammatory acne, but inconvenience and undesirable side effects prompted a search for more acceptable treatments. This study aimed to compare the clinical efficacy and safety of long-pulsed Nd: YAG laser 1064 nm versus intralesional botulinum toxin type-A (BTX-A) in inflammatory acne therapy. METHODS A prospective randomized split-face comparative study involved 30 patients with inflammatory acne. Each patient received long-pulsed Nd: YAG 1064 nm laser on one side, and intralesional BTX-A on the other side, monthly until improvement or maximum three sessions. Cases were assessed by acne lesions counting and grading of severity by Investigator's Global Assessment of acne (IGAs) at baseline, each session, and after 3 months follow-up. RESULTS A highly statistically significant improvement in lesions count and IGAs for both sides was observed, with statistically non-significant difference between both sides at end of treatment sessions. While, after 3 months follow-up, there was a more significant improvement at laser side. CONCLUSION Both long-pulsed Nd: YAG laser 1064 nm and intralesional BTX-A are safe and effective for acne therapy. Nd-YAG laser has a more prolonged efficacy and lower recurrence rate than intralesional BTX-A.

Abstract
Although intense pulsed light (IPL) has been commonly used in the field of medical cosmetics in recent years, the exact outcomes of IPL in the treatment of inflammatory skin diseases remain unclear. To assess the clinical evidence for the use of IPL in the treatment of various inflammatory skin diseases and propose evidence-based recommendations, we searched for relevant publications in the PubMed and Web of Science databases and provided updated information. The inflammatory skin diseases treated with IPL consisted of acne vulgaris, rosacea, psoriasis, hidradenitis suppurativa (HS), atopic dermatitis (AD), Riehl's melanosis, lupus erythematosus, cutaneous sarcoidosis, pilonidal cysts, and pigmented actinic lichen planus (PALP). The efficacy of IPL treatment for these inflammatory skin diseases was described and evaluated. Forty-two studies were included to provide this assessment. The evidence suggests that IPL can effectively and safely improve acne vulgaris and rosacea (recommendation grade B). For other described inflammatory skin diseases, IPL can be used as a tentative or supplementary treatment (recommendation grade C and D). The main complications include transitory erythema, edema, and pain, with the possibility of hyperpigmentation, blisters, and a burning sensation in some individuals.

Abstract
People struggling with acne vulgaris, not only experience skin eruptions and skin pain, but also report that their quality of life is worse compared with healthy people. This study examined, for the first time, the effect of sonophoresis on select skin parameters (sebum level) in young women suffering from acne vulgaris. The study included 60 women 19–23 years of age (M = 21.45, SD = 0.91) with mild and moderate facial acne. The inclusion criteria were 19–23 years of age, female or male gender, mild to moderate acne, no dermatological treatment within last 12 months, and no hormonal contraception (women). No men volunteered for the study, so the group was homogeneous. The patients were divided into two groups. Group A underwent a sonophoresis procedure using ultrasound and ultrasound gel combined with a green tea, bamboo extract ampule, and 5% lactic acid. Group B was the placebo group, where sonophoresis was performed using only ultrasound gel (no ampules). The members of the placebo group were told that they were undergoing sonophoresis with a green tea, bamboo extract, and 5% lactic acid ampule. Before and after the series of procedures, sebum levels were measured in the skin. Each patient underwent a series of five procedures using sonophoresis equipment at one-week intervals. Sonophoresis with green tea, bamboo extract, and 5% lactic acid contributed to the reduction of skin eruptions and sebum levels in the participants of the study (group A). The study results demonstrated that the combined use of plant preparations, lactic acid, and ultrasound had a positive effect on the skin of people suffering from acne vulgaris, including reduction of skin eruptions and sebum levels on the surface of the skin.

Abstract
Large numbers of local and systemic therapies are available for acne treatment. Common oral or topical retinoids, antibiotics, or keratolytics are used but sometimes are inconvenient, and side effects caused by these conventional therapies prompted a search for effective and safe treatments. This study aimed to evaluate the efficacy of intralesional platelet-rich plasma injection versus 1064 nm long-pulsed Nd:YAG laser in the treatment of moderate inflammatory acne vulgaris in both adolescents and post-adolescent patients. This split-face comparative study was carried out on thirty patients who suffered from moderate inflammatory and non-inflammatory acne vulgaris. The patients were classified into two groups: group I: adolescent (≤ 25 years) and group II: post-adolescent (< 25 years). Each group received four sessions of intralesional PRP injection on one side of the face and a long-pulsed Nd:YAG (1064 nm) laser on the other side with 2 weeks interval. Evaluation was done by blinded dermatologists using photographs and lesions counting and by patient satisfaction. Side effects were also noted. Both groups (adolescents and post-adolescent) showed a high statistically significant improvement of inflammatory as well as non-inflammatory lesions either in PRP or Nd:YAG laser–treated side with no significant difference between the two sides. The intralesional PRP injection and 1064 nm long-pulsed Nd:YAG laser are safe and effective methods for controlling inflammatory as well as non-inflammatory acne vulgaris in both adolescents and post-adolescent patients.

Abstract
BACKGROUND Keloid and hypertrophic scars are the most common types of pathological scars. They can cause itching, pain, erythema, and psychological stress due to cosmetic problems, decreasing the quality of life for affected individuals. The neodymium-doped yttrium aluminum garnet (Nd:YAG) multipurpose laser is used to treat pathological scars, and studies have shown that the Nd:YAG laser can markedly improve scarring. AIMS We performed a meta-analysis to evaluate the efficacy of the Nd:YAG laser in the treatment of keloid and hypertrophic scars. METHODS A literature search of PubMed, Web of Science, Scopus, Cochrane, Embase, CNKI, and Wanfang was performed between January 1st, 2010, and July 14th, 2021. The Vancouver Scar Scale (VSS) was used to evaluate treatment outcomes. We used the R version 4.0.0 software for statistical analysis. RESULTS The Nd:YAG laser improved the condition of keloid and hypertrophic scars and reduced VSS score (mean difference [MD]: 2.96, 95% confidence interval [CI]: 2.08-3.84, p < 0.01). There was no obvious difference in the results between regions. A subgroup analysis by scar type revealed that the curative effect of the Nd:YAG laser on keloid scars (MD: 2.02, 95% CI: 0.58-4.63, p = 0.10) was less marked compared with that on hypertrophic scars (MD: 3.05, 95% CI: 1.58-4.52, p < 0.01). With the combined use of the Nd:YAG laser and other treatment methods, a more significant change in VSS score was noted (MD: 4.28, 95% CI: 2.07-6.49). CONCLUSIONS This meta-analysis showed that the Nd:YAG laser can improve the condition of keloid and hypertrophic scars and effectively reduce VSS score. Moreover, the curative effect of this approach on keloid scars is less marked compared with that on hypertrophic scars.

Abstract
Acne vulgaris is a disease of the pilosebaceous unit and the most common inflammatory dermatosis worldwide. It is also associated with significant economic burden. Limitations of conventional topical and systemic treatments include long treatment course, intolerable adverse effects, antibiotic resistance, and patient compliance. Therefore, laser and light-based interventions present as alternative options over the past decade and have been used in combination with conventional pharmacological therapies and other physical modalities. An updated overview on the use of lasers and light-based devices in acne management is presented to help clinicians understand the safety and efficacy of these treatment options. The effectiveness of neodymium:yttrium aluminum garnet (Nd:YAG) for treating acne is supported by more high-level studies compared with other laser devices. There is limited evidence to support the use of CO2 lasers, potassium titanyl phosphate lasers, and 1565-nm non-ablative fractional lasers for treating acne. Among light devices, photodynamic therapy is the most studied, showing higher efficacies than some of the conventional topical and oral acne therapies. Intense-pulsed light and blue light therapies also show favorable outcomes. A limitation is that most studies are non-randomized and lack a control group, and report on a variety of device settings, treatment regimens, and outcome measures, making it challenging to summarize and generalize findings. Although the use of laser and light devices to treat acne is promising, further work with randomized controlled study designs and larger sample sizes will provide improved guidance on the application of these modalities.

Abstract
BACKGROUND The popularity of laser therapy in acne treatment has been increasing recently due to its safety, effectiveness, and convenience. Both 595-nm pulsed dye laser (PDL) and 1064-nm long-pulsed neodymium:yttrium-aluminum-garnet laser (Nd:YAG) have been successful in treating inflammatory acne lesions. However, clinical data from controlled comparative studies are still lacking. AIMS To compare the clinical efficacy of 1064-nm Nd:YAG with 595-nm PDL for the treatment of acne vulgaris. METHODS Thirty-four participants with mild to moderate facial acne were enrolled and then randomized to receive three, 2-week interval treatments with 1064-nm Nd:YAG on one side of the face and 595-nm PDL on the other side. Clinical assessments including acne lesion counts, acne erythema grading, and erythema index were performed at baseline, 2nd, 4th, and 8th week. Participants' satisfaction, preference, and adverse effects were recorded. RESULTS As compared with baseline, the significant reduction of mean inflammatory acne lesion counts, acne erythema grading, and erythema index was demonstrated on 595-nm PDL-treated sides and 1064-nm Nd:YAG-treated sides. However, there were no significant differences between both sides. The participants were satisfied with both laser treatments, but the participants preferred 1064-nm Nd:YAG over 595-nm PDL treatment. The adverse effects were less on 1064 nm Nd: YAG-treated sides. CONCLUSIONS 1064-nm Nd:YAG and 595-nm PDL treatments are equally effective in reducing inflammatory acne lesions and acne erythema in mild to moderate facial acne vulgaris.
