Abstract
Wound healing occurs as a response to disruption of the epidermis and dermis. It is an intricate and well-orchestrated response with the goal to restore skin integrity and function. However, in hundreds of millions of patients, skin wound healing results in abnormal scarring, including keloid lesions or hypertrophic scarring. Although the underlying mechanisms of hypertrophic scars and keloid lesions are not well defined, evidence suggests that the changes in the extracellular matrix are perpetuated by ongoing inflammation in susceptible individuals, resulting in a fibrotic phenotype. The lesions then become established, with ongoing deposition of excess disordered collagen. Not only can abnormal scarring be debilitating and painful, it can also cause functional impairment and profound changes in appearance, thereby substantially affecting patients' lives. Despite the vast demand on patient health and the medical society, very little progress has been made in the care of patients with abnormal scarring. To improve the outcome of pathological scarring, standardized and innovative approaches are required.

The comparison of the efficacy and safety of fractional 1064 nm Nd:YAG picosecond laser and nonablative fractional 1565 nm laser in the treatment of enlarged pores: A prospective split-face study. Lasers Surg Med 2023; 55:169-177. [PMID: 36718089 DOI: 10.1002/lsm.23635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 11/29/2022] [Accepted: 01/16/2023] [Indexed: 02/01/2023]
Abstract
BACKGROUND AND OBJECTIVES To compare the efficacy and safety of fractional 1064 nm Nd:YAG picosecond laser and nonablative fractional 1565 nm laser in the treatment of enlarged pores. STUDY DESIGN/MATERIALS AND METHODS Twenty patients received five monthly treatments at months 0, 1, 2, 3, and 4 and were followed up at months 5, 6, and 7. All patients were treated by fractional 1064 nm Nd:YAG picosecond laser (FxPico) on the left face, and nonablative fractional 1565 nm laser (ResurFx) on the right face as a control. RESULTS For the 19 patients who completed the study, both sides demonstrated significant improvement on pore counts (p < 0.01), while there was no significant difference between the two sides 3 months after the final treatment (p = 0.092). Excellence rate on the FxPico side (57.9%) was significantly better than the ResurFx side (36.8%) (p < 0.05). Sebum secretion and porphyrin value significantly decreased on both sides after five treatments and there was a higher reduction of sebum level on the ResurFx side. There was no difference between the two therapies in terms of overall satisfaction. Pain of treatment for the ResurFx side (average VAS 4.45 ± 1.60) is significantly higher than that for the FxPico side (average visual analog scale [VAS] 1.48 ± 1.36) (p < 0.001). Erythema, edema, and petechiae were common adverse effects and were mild to moderate. There was significantly higher incidence of hyperpigmentation for the ResurFx side (52.6%) compared with that for the FxPico side (5.3%) (p < 0.001). CONCLUSION Fractional 1064 nm Nd:YAG picosecond laser and nonablative fractional 1565 nm laser both are effective, efficient, and safe treatment regimens for enlarged pores, while fractional 1064 nm Nd:YAG picosecond laser has better clinical response with less treatment pain, shorter recovery period and much lower induction of hyperpigmentation.

Abstract
Facial pores are visible openings of pilosebaceous follicles, and they are one of the major factors influencing facial skin appearance. This article aims to evaluate and compare the efficacy and safety of 1565-nm non-ablative fractional laser (NAFL) and long-pulsed 1064-nm Nd:YAG laser (LPNY) in treating enlarged facial pores. All subjects were treated with NAFL on their left faces and LPNY on their right. Five treatments were administered at 2-week intervals, with one follow-up session 2 months after the final treatment. Treatment efficacy was evaluated by subjective (pore improvement and subject satisfaction ratings) assessments and objective (pore number) assessments. At each appointment, any side effects or complications were recorded to evaluate the safety of the two lasers. A total of 18 individuals participated in this study. At the 2-month follow-up, NAFL and LPNY sides had significant reduction in pores (p < 0.0001 and p < 0.0001, respectively). However, there was no statistically significant difference in the mean number of pore reductions on either side (p > 0.05). There was no significant difference in pore improvement ratings and satisfaction ratings between the two sides (p > 0.05 and p > 0.05, respectively). Both lasers showed minimal side effects. Both lasers effectively treated enlarged facial pores and were well tolerated. The side effects of the 1064-nm LPNY were less severe than those of the 1565-nm NAFL.

Abstract
BACKGROUND Self-harm scars are a consequence of deliberate self-injury, serving as a visual reminder for involved individuals. Patients often reach out to their providers seeking treatment for their scars. However, there is currently no standard for treating self-harm scars, because multiple options are being explored. OBJECTIVE A scoping review was conducted to identify and characterize the body of literature on different treatments for self-harm scars, including surgical, laser, and vitamin A management. METHODS Thorough literature searches were conducted in PubMed/MEDLINE, EMBASE, and CINAHL Complete. The search strategy was designed and implemented by a medical librarian. RESULTS Of 510 retrieved articles, 4 described laser treatments, 8 described surgical treatments, and 2 described vitamin A treatments. CONCLUSION A multidisciplinary approach is critical for the selection and outcome of the treatment of self-harm scars.

Abstract
Microneedle fractional radiofrequency (MFR) and non-ablative 1565 nm fractional laser (NAFL) have recently been introduced as new techniques to address the growing concern of facial photoaging. In this prospective randomized split-face study, we wanted to compare the safety and efficacy of MFR with that of NAFL for the treatment of facial photoaging in Asian patients. Fifteen healthy Chinese patients were enrolled for this randomized split-face study. Each patient underwent three sessions of treatment with MFR and NAFL on opposite sides of their face, one month apart. A blinded outcome assessment of the photoaging severity was performed by two independent plastic surgeons on a 5-point visual analogue scale (VAS, 0-4). Patient satisfaction was also scored based on a 5-point VAS (0 = dissatisfaction, 4 = extremely satisfied). Sagging of the nasolabial groove was evaluated using the Antera 3D camera, facial wrinkles and pores using the VISIA skin analysis system. Any adverse events that occurred during the study were also evaluated. Based on the VAS scores and results from the Antera 3D and VISIA, it was noted that there was a significant improvement in facial skin laxity, wrinkles, and pores, and lesser sagging of the nasolabial groove on both the MFR and NAFL sides of the face, compared with that of the baseline. Most patients were satisfied with the treatment and reported tolerable pain and crusting. Although no significant differences were observed between the MFR and NAFL treatments, the NAFL treatment resulted in a shorter downtime(4.56 ± 2.72d) than the MFR treatment(6.96 ± 3.27d). This study confirms the efficacy of MFR and NAFL treatments for facial skin rejuvenation in Asian patients. Furthermore, the therapies were found to be safe and well-tolerated. Our findings suggest that NAFL may be a more convenient treatment modality for facial photoaging because of its shorter downtime. However, sagging of the nasolabial groove was more improved by the MFR treatment than by the NAFL treatment.

Abstract
BACKGROUND Deliberate self-harm (DSH) can be defined as self-inflicted injury without an intention to suicide, and it may result in scar formation with a particular shape. AIMS There is no treatment algorithm for DSH scars, nor is there a gold standard for the treatment of hypertrophic scars. Therefore, we aimed to share our experience with Er: YAG laser treatment of self-inflicted razor blade incision scars. PATIENTS/METHODS The study involved 18 patients with DSH scars treated with fractional ablative Er: YAG laser (MCL 31 Asclepion laser Technologies) between 2017 and 2020, with the parameters of 40 J/cm2 , 300 µs, and 4 Hz. The sessions were repeated by increasing 10 joules in every session with 4-week intervals until reaching a maximum of 80 joules. The patients were evaluated retrospectively by two different dermatologists in terms of scar improvement over digital photographs taken before and 4 weeks after the treatment. Evaluations have been made based on a 4-point score (0:no change, 1:1%-25% mild, 2:26%-50% moderate, 3:51%-75% well, and 4:76%-100% excellent improvement). RESULTS After the third session, 90.9% of the patients showed a moderate improvement. After the fourth session, only 27.2% of the patients had a good, and 63.2% of the patients had a moderate improvement rate. CONCLUSIONS Er: YAG laser is a safe and effective treatment method for the hypertrophic scars induced by razor blades. Also, we believe that combined treatments with other treatment modalities will provide better results in DSH scars.

Abstract
The non-ablative fractional erbium-doped glass 1,565-nm laser (NAFL) and the microneedle fractional radiofrequency (MFR) procedures are effective treatments that enable periorbital skin rejuvenation. To compare the clinical effectiveness and side effects of MFR and the NAFL for baggy lower eyelids (BLEs) in the Chinese population. Fifteen Chinese subjects with BLEs received three split-face treatments on a monthly basis randomly. Objective and subjective assessments were performed at baseline, as well as 1 month and 3 months after the third treatment. The results were evaluated using Antera-3D and CineScan systems. Blinded investigator assessments were performed by two plastic surgeons using a 0 to 4 score in six anatomic categories of BLEs. The patients also reported their level of satisfaction based on a four-point score. Most of the patients reported a greater than 47% satisfaction rate with both treatments. The cumulative contribution scores of prolapse of orbital fat, hollow tear trough, and skin laxity for each category variable declined with time. Using Antera 3D, the volume of elevation (mm3) decreased from 0.6 ± 0.4 to 0.4 ± 0.3 and from 0.6 ± 0.3 to 0.3 ± 0.3, the elevation area (mm2) decreased from 17.0 ± 8.4 to 13.0 ± 7.1 and from 17.0 ± 7.8 to 10.0 ± 5.6, and the maximum peak height (mm) also decreased from 0.10 ± 0.04 to 0.06 ± 0.04 and from 0.10 ± 0.03 to 0.06 ± 0.02 in the MFR and NAFL groups, respectively. Using CineScan, the depth of middle orbital fat (mm) decreased significantly from 10.2 ± 2.2 to 8.0 ± 0.7 and from 9.8 ± 1.1 to 8.0 ± 0.9 and the length of orbital fat significantly decreased from 9.2 ± 1.2 to 7.7 ± 0.7 and from 9.7 ± 1.4 to 7.8 ± 0.6 in the MFR and NAFL groups, respectively. MFR and NAFL therapies were effective for the treatment of BLEs, especially in BLE patients with skin elasticity in addition to tear trough deformity and orbital fat prolapse. Trial registration number: NCT04237324. Trial register: ClinicalTrials.gov. Level of Evidence: Level I, therapeutic study.

Abstract
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.

Abstract
Scars developing after wrist cutting (a deliberate action of self-harm) have various patterns and are difficult to treat. In addition, they can occur at anatomically prominent sites and are easily recognized as caused by self-harm; thus, scars can cause lifelong regrets. However, there are no standard treatment guidelines for wounds inflicted through self-harm. This study aimed to evaluate the effectiveness of our novel technique using 90-degree rotated skin grafts, which were thinly collected at a thickness of 250 μm from a wound site, together with minced-skin grafts. Methods Five regions on the forearm of 5 Japanese women (age, 19-29 years) were treated from July 2011 to April 2012. The skin at the scar site was cut with an electric dermatome at a thickness of 250 μm. The scar contained therein was excised, and the skin was rotated 90 degree and transplanted. The scar remaining in the dermis of the wound was resected and resurfaced. At the site where the skin graft was insufficient, the skin was processed into a minced shape and then transplanted (minced-skin graft). Results In all cases, skin grafting was performed. The scar was successfully camouflaged and transformed into a socially acceptable appearance. At the wound site, the skin texture was reproduced. Following skin grafting, nodules, pigmentation, and redness around the graft transiently occurred, which then disappeared over time. No scar contractures were observed. Conclusion A combination of thin-skin graft rotated 90 degrees and minced-skin graft is useful in camouflaging a wide variety of deliberate self-harm scars.

Abstract
BACKGROUND Patients suffering from hypertrophic scars often describe esthetic, functional, and psychological impairments. While current guidelines for the treatment of pathologic scarring recommend the use of onion extract containing gels and sheets, hard evidence for its efficacy remains scarce due to inconsistent data. Onion extract and allantoin containing occlusive overnight intensive patches (OIP) were introduced as a recent option for noninvasive scar management. However, objective data demonstrating their efficacy are missing. AIMS This study is the first to objectively evaluate the benefit and safety of an OIP for hypertrophic scars using a three-dimensional imaging device and a standardized scar scale. METHODS Twelve patients with untreated, three to twelve months old hypertrophic scars received an OIP for 3 months. The assessment was performed using PRIMOS®pico , a three-dimensional imaging device and POSAS, a standardized scar questionnaire at baseline, one and 3 months after the last treatment. RESULTS Objective evaluation at three months follow-up (FU) showed a significant decrease in scar height of 28.8% (baseline mean: 2.08 ± 0.68 mm, three months FU mean: 1.48 ± 0.52 mm) and a reduction in scar volume of 31.9% (baseline mean: 454.33 ± 265.53 mm3, 3 months FU mean: 309.58 ± 224.28 mm3). Pain and pruritus subsided under treatment. There were no negative side effects. CONCLUSION Overnight intensive patches is a convenient, painless, safe, affordable and effective prevention and treatment option for hypertrophic scars. Treatment should be performed at least for 3 months for visible effects.

Abstract
BACKGROUND Intralesional 5-fluorouracil (5-FU) in combination with triamcinolone acetonide (TAC) has been recommended as a promising alternative for keloids not responding to silicone-based products, cryotherapy or intralesional corticosteroids alone. Although numerous studies support the efficacy of this regime, there is a lack of objective data. OBJECTIVES In this study, we evaluate the therapeutic effect of four courses of intralesional 5-FU in combination with TAC (3 : 1) utilizing 3D analysis (PRIMOS®pico ), ultrasound and scar scales such as the Patient and Observer Scar Assessment Scales (POSAS) and the Dermatology Life Quality Index (DLQI). METHODS Twenty-five patients with keloids were treated using 5-FU and TAC every 4 weeks. Objective assessments were performed and the scar scales administered at baseline, as well as during consecutive visits at 1- and 12-month follow-up (FU). Routine laboratory tests were performed at baseline and at 1-month FU. RESULTS 3D PRIMOS and ultrasound measurements revealed highly significant and stable reductions in height (baseline mean score: 4.0 ± 1.7 mm, 1-month FU mean score: 1.5 ± 0.8 mm, 12-month FU mean score: 1.8 ± 0.9 mm, P = <0.0001), volume (baseline mean score: 1,105 ± 911.5 mm3 , 1-month FU mean score: 416.1 ± 218.1 mm3 , 12-month FU mean sore: 431.2 ± 253.6 mm3 , P = <0.0001, respectively) and penetration depth of keloids (relative reduction between baseline and 12-month FU of 74.4%, P = <0.0001). The POSAS and DLQI scales confirmed significant objective and subjective improvements in scar appearance in all categories. The life quality associated with keloid appearance improved from a 'moderate effect' to a 'small effect' throughout the course of the study. CONCLUSIONS Results of this study confirm the efficacy and safety of the combination of 5-FU and TAC in keloids. Treatments were well tolerated and demonstrated stable results at 12-month FU.

Abstract
Introduction: Induction of collagen and elastin remodeling in the human skin can be achieved by non-ablative fractional laser (NAFXL) and ablative fractional laser (AFXL). Our objective was to compare the safety, efficacy, tolerability, and ability to induce collagen and elastin remodeling of NAFXL versus AFXL in a series of treatments over time.Materials and Methods: In this prospective, proof of principle, single-case study, the safety, tolerability and efficacy of the laser systems were assessed via histopathology and clinical evaluations including photographs. Optical biopsies by means of multiphoton tomography (MPT) were used to evaluate the induction of collagen and elastin remodeling.Results: Treatments by both NAFXL and AFXL were well tolerated. The NAFXL system was found to be less painful and resulted in a shorter down- and healing times. MPT findings showed the superior capability of the AFXL procedure to induce collagen; on the other hand, elastin induction was more pronounced after NAFXL treatments.Conclusions: While NAFXL is as effective and safe as the traditional AFXL, it is better tolerated and has a shorter downtime. Serial optical biopsies over time over time can be a useful tool to assess the induction of collagen and elastin remodeling in the human skin.
