Novel 532-nm Q-switched Nd: YAG laser for the treatment of melasma and rejuvenation: a prospective, randomized controlled comparison with 1,064-nm Q-switched Nd: YAG laser. Int J Dermatol 2024; 63:1242-1251. [PMID: 38411341 DOI: 10.1111/ijd.17091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/28/2024]
Abstract
BACKGROUND Melasma is a common pigmentary and photoaging disorder. Although various treatments, including 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QS-Nd: YAG) laser toning, are available for melasma, results are often unsatisfactory. OBJECTIVE We aimed to determine the efficacy and safety of 532-nm QS-Nd: YAG laser (shortwave toning) in patients with melasma and facial rejuvenation. METHODS Fifty-two patients were recruited to receive either 1,064-nm QS-Nd: YAG laser or 532-nm QS-Nd: YAG laser every 2 weeks for 8 sessions and a 2-month follow-up visit in a randomized controlled double-blinded study. The primary outcome measure was the Melasma Area and Severity Index (MASI) score. Dermoscope and high-frequency ultrasound (HFUS) were used to assess the improvement of melasma and photoaging. RESULTS 532-nm QS-Nd: YAG laser achieved significantly higher improvement in the MASI score (P = 0.000). The Dermoscopic melasma score (DMS) displayed significant change and confirmed the improvement. HFUS showed a significant decrease in the thickness of the subepidermal low-echogenic band (SLEB) and increases in dermal thickness and dermal density in both groups (P = 0.000 for all). The rate of very satisfied responses was significantly higher in the 532-nm laser group (P = 0.001). There was no significant difference in the visual analog scale pain assessment score (P = 0.248) and recurrence rate (P = 0.734) between the two groups. CONCLUSION 532-nm QS-Nd: YAG laser (shortwave toning) proved to be an effective and safe treatment for melasma and rejuvenation. Shortwave toning was significantly better for pigmentation clearance, while 1,064-nm laser showed better improvement in skin rejuvenation.

Efficacy, safety, tolerability and treatment durability of microneedling plus topical tranexamic acid in combination with topical modified Kligman lightening formula for melasma: A four-arm assessor and analyst blinded randomized controlled clinical trial. J Cosmet Dermatol 2024. [PMID: 39016678 DOI: 10.1111/jocd.16464] [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: 05/25/2024] [Accepted: 07/01/2024] [Indexed: 07/18/2024]
Abstract
BACKGROUND The challenging management of melasma highlights the inadequacies of conventional therapies and their high risk of recurrence. Integrating microneedling for device-assisted drug delivery with tranexamic acid (TA), recognized for its melanin synthesis inhibition, presents a novel approach that warrants further investigation to fully assess its potential in enhancing melasma treatment efficacy. METHODS Fifty moderate to severe melasma patients participated in this randomized outcome-assessor-blinded controlled trial. Patients were randomly allocated into two main groups. Group A received a modified Kligman formula on one hemi-face on alternate nights for 2 months (A1) and three sessions of microneedling with 10% topical TA on the other hemi-face at 1-month intervals (A2). Group B used the same modified Kligman formula on both sides of the face, with one side additionally receiving three sessions of microneedling with 4% TA (B1) and the opposite side with 10% TA (B2). Primary outcomes were % Modified Melasma Area and Severity Index (mMASI) and % visual analogue scale (VAS) change during 6 month follow-up. Adverse events including post-inflammatory hyperpigmentation (PIH) and treatment tolerability were recorded. RESULTS Compared to baseline, the mean mMASI reduction immediately after the final session was higher in A1, B1, and B2 (56.84%, 50.88%, and 55.87%, respectively) than in A2, which saw only a 13.16% reduction. Efficacy notably declined after the cessation of treatment across all groups. While the efficacy within groups A1, B1, and B2 was comparable, microneedling with 4% or 10% TA combined with the topical modified Kligman formula proved more potent in patients at a lower risk of PIH. Overall, 22% of patients reported PIH, particularly in the A2 group (28% of hemi-faces), with its occurrence significantly associated with treatment during warmer seasons and in darker skin phototypes. Other adverse events were not observed in any patient. Patient satisfaction was highest in groups B1 and B2, where approximately 72% reported 'excellent' satisfaction. The lowest durability rate (16%) was observed in group A2, while the highest (72%) was seen in group B2, comparable with groups A1 and B1. Treatment tolerability was reported 100% in all groups. CONCLUSION It was found that the modified Kligman formula outperformed microneedling-TA alone. However, with optimal patient selection, particularly targeting those at lower risk for PIH with lighter skin phototypes and scheduling treatments during less-sunny seasons, combining microneedling with 4% or 10% TA and the modified Kligman formula significantly enhanced efficacy and satisfaction rates compared to conventional topical treatment.

Indian Dermatol Online J 2024; 15:593-598. [PMID: 39050052 PMCID: PMC11265735 DOI: 10.4103/idoj.idoj_551_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 01/22/2024] [Accepted: 02/02/2024] [Indexed: 07/27/2024] Open
Abstract
Background Response to the current available treatments of melasma, dermal type, in particular, is usually gradual and can result in possible side effects. Aim and Objectives In this study, we aim to evaluate the efficacy of the combination of plasma rich in growth factors (PRGF) and topical 4% hydroquinone (HQ) in comparison with monotherapy using topical 4% HQ alone in the treatment of dermal type of melasma. Materials and Methods This is a single-blinded, randomized, split-face clinical trial on twenty female patients with dermal type of melasma. Patients were asked to apply topical 4% HQ on both sides of their face at night for 6 months. In each participant, one side of the face was randomly chosen to receive monthly intradermal injections of PRGF for 3 sessions. Efficacy of the treatment was assessed using hemi melasma area and severity index (MASI) score, physician's global assessment (PGA), and patients' global assessment (PtGA). Results Both groups revealed significant improvement in hemi-MASI score during the treatment course. Mean percentage of improvement at the end of study was 40.38 ± 6.04% and 33.42 ± 3.23% in the combination therapy and monotherapy groups, respectively (P = 0.31). PGA demonstrated excellent-to-marked improvement in melasma in 25% and 5% of patients in the combination therapy and monotherapy groups, respectively (P = 0.31). PtGA showed high levels of satisfaction in 15% of patients in the combination therapy group (vs. 0% in the monotherapy group) (P = 0.05). Conclusion Differences between the two treatment groups in terms of hemi-MASI and PGA scores were not statistically significant; however, patients demonstrated higher satisfaction with combination of PRGF and topical 4% HQ compared with topical HQ alone. Thereby, combination of PRGF and topical 4% HQ can be suggested as a safe alternative therapeutic approach and may hold promise in the development of future therapeutic options for dermal type of melasma.

Abstract
BACKGROUND Transepidermal drug delivery is a novel therapeutic technique to boost efficacy of topical drugs. AIM In this clinical trial we evaluate the efficacy of the combination of fractional carbon dioxide (FCO2) laser and bimatoprost solution compared to bimatoprost alone in the treatment of alopecia areata. METHODS This is a prospective intra-patient comparative randomized clinical trial on 20 patients with alopecia areata. In each participant two patches were chosen to randomly receive either topical 0.03% bimatoprost solution (twice a day for 12 weeks) alone or in combination with FCO2 laser (every 2 weeks for 12 weeks). Then response to treatment was evaluated by the measurement of the severity of alopecia tool score system (SALT) score, percentage of hair regrowth, physician assessment and patients' satisfaction. RESULTS SALT score was reduced significantly during treatment sessions and after a 3-month follow-up in both treatment groups (p = 0.000). The mean percentage of improvement in SALT score in the combination therapy and monotherapy groups were 46.43 ± 4.35% and 21.16 ± 4.06% at the end of the study and 46.42 ± 5.75% and16.11 ± 3.10% at the end of the follow-up period, respectively (p = 0.000). A general linear model of two-way analysis demonstrated a significantly superior outcome in the combination therapy group compared to the monotherapy group during time (F1.6, 13.2 = 43.8. p = 0.000). CONCLUSION Fractional ablative laser can be considered as an assistant method for enhancing of efficacy of topical drugs especially in refractory cases of patchy alopecia areata.

Abstract
BACKGROUND Facial hyperpigmentation can negatively affect an individual's emotional and psychosocial well-being. AIMS Assess safety and tolerability of a combination of microdermabrasion (DG) procedures using a novel brightening pro-infusion serum (EC-DG) with a targeted at-home treatment regimen in subjects with mild to severe facial hyperpigmentation, including melasma, post-inflammatory hyperpigmentation, and dark spots. PATIENTS/METHODS This 12-week, open-label study enrolled 18 subjects (Fitzpatrick skin types I-IV) who underwent 6 in-office DG procedures with EC-DG (one procedure administered biweekly), along with daily topical application of a brightening treatment serum and dark spot cream. End points included change from baseline across multiple skin quality attributes and the Melasma Area and Severity Index (MASI), self-assessment questionnaires, and tolerability assessments. RESULTS The combination treatment was well tolerated and resulted in significant (p ≤ 0.05) improvements from baseline in radiance, tactile roughness, and moisturization/hydration immediately after the first treatment, in MASI score at day 3, and in overall hyperpigmentation at week 4. Most (94.1%) subjects were satisfied with treatment. CONCLUSIONS DG procedures using EC-DG combined with a targeted at-home skincare regimen are effective and tolerable for treating facial hyperpigmentation across a broad range of skin types.

Abstract
Melasma is a commonly occurring pigmented skin condition that can significantly affect one's appearance, described as symmetric hyperpigmentation that presents as irregular brown to gray-brown macules on various facial areas, such as the cheeks, forehead, nasal bridge, and upper lip, along with the mandible and upper arms. Due to its complex pathogenesis and recurrent nature, melasma management is challenging and the outcomes following treatment are not always deemed satisfactory. Solely treating hyperpigmentation may prove ineffective unless paired with regenerative techniques and photoprotection, since one of the main reasons for recurrence is sun exposure. Hence, the treatment protocol starts with addressing risk factors, implementing stringent UV protection, and then treatment using different strategies, like applying topical treatments, employing chemical peels, laser and light therapies, microneedling, and systemic therapy. This review aims to provide a summary of the effectiveness and safety of the frequently employed laser and light therapies for treating melasma, focusing on laser therapy as a treatment for melasma.

Abstract
BACKGROUND Melasma is a prevalent, persistent hyperpigmentation disorder that negatively affects the psychological health of patients. However, the treatment outcome remains unsatisfactory due to the complexity of pathogenesis, recurrence characteristics, and relatively high morbidity. OBJECTIVES To compare the performance of laser-related therapies in improving the melasma area severity index (MASI) score of melasma and the occurrence of adverse effects by network meta-analysis (NMA). METHODS From the inception to November 2022, eligible randomized controlled trials were identified. Two investigators independently searched relevant studies from PUBMED, EMBASE, and the Cochrane Library database. RESULTS A total of 39 clinical studies with 1394 participants were eligible for enrollment. For efficacy, the NMA demonstrated that Q-switched Nd: YAG laser + topical medications (QSND+TM) was superior to Q-switched Nd:YAG laser (QSND) [MD = -4.21 (-6.80, -1.63)], Er: YAG laser + topical medications (ERYL+TM) [MD = -3.52 (-6.84, -0.19)], and picosecond laser + topical medications (PICO+TM) [MD = -4.80 (-9.33, -0.27)]. The microneedling + topical medications (MN+TM) was superior to picosecond laser (PICO) [MD = -5.26 (-10.44, -0.08)] and topical medications (TM) [MD = -5.22 (-9.20, -1.23)]. The top five of the surface under the cumulative ranking curve value (SUCRA) are Q-switched Nd:YAG laser + topical medications (QSND+TM 85.9%), oral tranexamic acid (oTA 80.1%), microneedling + topical medications (MN+TM 79.7%), Q-switched Nd:YAG laser + intense pulse light (QSND+IPL 78.9%), and fractional carbon dioxide laser + topical medications (FCDL+TM 70.5%). CONCLUSIONS In conclusion, the Qs-Nd:YAG laser with topical medications is the first choice for treating melasma according to the SUCRA value. Among the three treatment modalities, namely MN + TM, PICO, and TM, our recommendation favors MN+TM as the superior choice for enhancing the curative efficacy in melasma. However, the actual clinical choice should also take into account the adverse effects, the skin type of the patient, the duration of the disease, and other relevant factors.

Abstract
Background Melasma is a common dermatosis in both men and women showing varying degrees of success with treatment. Relapse of melasma is high in dark skin types, which necessitates the need for finding a modality of treatment, which not only treats but also prevents relapse. Aims To study the effectiveness of platelet-rich plasma (PRP) in patients of melasma both clinically and dermoscopically in dark skin types. Materials and Methods A prospective study of 20 female patients of Fitzpatrick skin type IV-V with mixed type of melasma and bilateral involvement of the face were enrolled for the study. PRP was injected intradermally at 4 weeks interval for three sittings, and the results were assessed clinically (by modified melasma area and severity score) and dermoscopically. Patients were counselled to ensure strict sun protection measures. Patient satisfaction was noted at baseline, 4 weeks, 8 weeks, and 12 weeks. Patients were followed up for 3 months to see for any relapse of the pigmentation. The follow-up showed no relapse of melasma in these patients. Statistical Analysis Analysis of variance was used with Bonferroni correction for modified melasma area and severity score at various time interval. Subject global aesthetic improvement scale (SGAIS) and physician global esthetic improvement scale (PGAIS) were expressed in counts. P-value ≤ 0.05 was considered significant. Results Modified melasma area and severity score and dermoscopic changes showed statistically significant improvement compared at the end of study in mild to severe cases. The subjective assessment was made by PGAIS. Patient satisfaction levels (assessed by SGAIS) also showed significant improvement in successive weeks of treatment. Few patients had mild redness and burning post procedure, which resolved spontaneously after few hours. Conclusion From this study we concluded that PRP shows a significant improvement in melasma after 12 weeks of treatment with no relapse even after 3 months. Hence, PRP may be used not only as an adjuvant but also as a first line treatment in the view of longer sustained results when combined with strict sun protection. There is a paucity of studies showing results of PRP treatment in dark skin types, which is more resistant to treatment than lighter skin. Moreover, clinical improvement should not be the only parameter to decide on stopping treatment as chances of relapse can be higher. Dermoscopic evaluation helps in determining the changes in vasculature (telangiectasias) and pigmentation (dots and globules), which are better indicators of success of treatment.

Abstract
OBJECTIVE To investigate the efficacy and safety of broadband light (BBL) combined with intradermal injection of tranexamic acid for treating melasma. METHODS 120 women with melasma admitted to our hospital from January 2021 to April 2022 were randomly categorized into the following groups: control group, treated with 250 mg tranexamic acid given orally twice daily, except during menstruation; group I, treated with BBL (Sciton, Inc., USA) monthly; group II, received intradermal injections of tranexamic acid monthly; and group III, treated with BBL with intradermal injection of tranexamic acid monthly. Treatment in each group lasted three months. The MASI (Melasma Area Severity Index) and VISIA (Canfield VISIA Complexion Analysis) were used for evaluation. RESULTS After treatment course, MASI scores and VISIA brown spot and red zone ranking improved in all four groups (p < 0.05). The decrease in MASI scores and improvement rates of VISIA brown spot and red zone rankings were not significantly different among the control group, group I, and group II; however, the decreased MASI scores and improvement rates of VISIA brown spot and red zone rankings were significantly higher in group III than in the other three groups (p < 0.05). CONCLUSION The effect of BBL combined with the intradermal injection of TA in the treatment of melasma is remarkable. This combination therapy can be an alternative and effective treatment for managing melasma.

Abstract
Purpose Laser and intense pulsed light (IPL) treatments are preferred over invasive procedures due to less pain. This study looked at the efficacy and safety of IPL and Erbium fractional laser for patients with striae gravidarum (SG). Patients and Methods All 60 patients with SG were successfully enrolled in the study. IPL treatment was followed by Erbium fractional laser (wavelength 2940 nm) treatment at 4-week intervals for a total of three treatments. SG elasticity was assessed with a SEM575 custom instrument and patients were scored for SG span with an Antera 3D multifunctional skin imaging analyzer. A 3D skin impact system was used to assess patients' epidermal thickness. A visual analog scale (VAS) was used to assess patients' pain scores during the treatment period. Improvement in stretch marks was assessed with the Global Aesthetic Improvement Scale (GAIS). The occurrence of adverse events was recorded at a follow-up of 3 months. Patient satisfaction with the outcome of the treatment was also recorded. Results Area of stretch marks decreased from 7.89 ± 0.49 cm2 pre-treatment to 4.94 ± 1.16 cm2 post-treatment (P < 0.001). The grayness values and atrophy of stretch marks were reduced after treatment. Furthermore, skin elasticity and thickness at the lesions of patients increased significantly after the treatment (P < 0.001), while the width of the stretch marks significantly decreased (P < 0.001). The VAS score was 5.45 ± 1.31, the incidence of adverse events was 25%, and patient satisfaction with the efficacy was 96.67%. Conclusion IPL combined with Erbium fractional laser improves the area and atrophy of SG, lightens the color, and increases the elasticity and thickness of the skin, with high treatment safety and remarkable clinical results.

Abstract
PURPOSE This article attempted to describe the efficacy and safety of 1064QNYL in combination with other treatments for refractory melasma. METHODS Two researchers independently retrieved randomized controlled trials (RCTs) according to inclusion and exclusion criteria. Primary outcome was evaluated with MASI and mMASI scores in control group and experiment group. The secondary outcome was evaluated with MI scores. We calculated 95%CI of standardized mean difference (SMD) and heterogeneity of the included literature by Higgins I2 test, and assessed publication bias by Funnel plots, Egger's, and Begg's tests. RESULTS A total of 12 articles including 322 subjects were analyzed. Experiment group was treated with 1064QNYL combined with single treatment (e.g., PDL, IPL, RF, TA). Control group was treated with 1064QNYL alone. A greater reduction of Melasma Area and Severity Index (MASI)/modified Melasma Area and Severity Index (mMASI) scores were shown in experiment group than that in control group at the end of the treatment (SMD, -0.37; 95%CI -0.70 to -0.04, p=0.03, I2 =33%). The SMD of MI scores further supported this conclusion by -0.32 (95%CI -0.63 to -0.02, P =0.04, I2 =27%). As for adverse events (AEs), combined treatment gave rise to more mild burning, stinging, and erythema that resolved spontaneously. Several studies reported focal purpura, punctate leukoderma, hyperpigmentation and hypopigmentation, and so on. CONCLUSION Combined 1064QNYL treatment was better than single laser treatment, with the highest short-term benefit and long-term follow-up to maintain the effect in favor of combined treatment.

The Low-Fluence Q-Switched Nd:YAG Laser Treatment for Melasma: A Systematic Review. Medicina (B Aires) 2022; 58:medicina58070936. [PMID: 35888655 PMCID: PMC9323185 DOI: 10.3390/medicina58070936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 07/07/2022] [Accepted: 07/08/2022] [Indexed: 11/17/2022] Open
Abstract
Melasma is a common pigmentary disorder with a complex pathogenesis, of which the treatment is challenging. Conventional treatment often leads to inconsistent results with unexpected pigmentary side effects and high recurrence rates. Recently, the low-fluence Q-switched Nd:YAG laser (LFQSNY) has been widely used for treating melasma, especially in Asia. We reviewed literatures on the LFQSNY treatment of melasma published between 2009 and May 2022 to evaluate the efficacy and adverse events, including its combination therapy. A systematic PubMed search was conducted and a total of 42 articles were included in this study. It was hard to summarize the heterogenous studies, but LFQSNY appeared to be a generally effective and safe treatment for melasma considering the results of previous conventional therapies. However, mottled hypopigmentation has been occasionally reported to develop and persist as an adverse event of LFQSNY, which may be associated with the high accumulated laser energy. When used aggressively, even LFQSNY can induce hyperpigmentation via unwanted inflammation, especially in darker skin. Although few studies have reported considerable recurrence rates three months after treatment, unfortunately, there is a lack of the long-term follow-up results of LFQSNY in melasma. To enhance the effectiveness and reduce the adverse events, LFQSNY has been used in combination with other treatment modalities in melasma, including topical bleaching agents, oral tranexamic acid, chemical peeling, or diverse energy-based devices, which generally reduced side effects with or without significant superior efficacy compared to LFQSNY alone.

Abstract
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.

Abstract
BACKGROUND Melasma is considered as a type of acquired facial pigmentary disorder that is challenging to treat. Low-fluence 1,064 nm Q-switched Nd: YAG laser (LQSNY) has clinical benefits against melasma, however there are some disputes. OBJECTIVE To explore these contentious views, we conducted a meta-analysis and systematic review to evaluate the efficacy and safety of LQSNY monotherapy and combined therapy for the treatment of melasma. METHODS The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for relevant articles from inception to July 2021. The resulting data were analyzed using the Review Manager 5.3 software. RESULTS Twelve eligible studies comprising 358 patients were included. No significant differences in melasma area and severity index (MASI) were observed between the LQSNY and drug groups (mean difference (MD):-0.26, 95% confidence interval (CI):-1.16-0.64, P=0.57). We found that combination therapy with LQSNY and drugs had a greater MASI improvement compared to LQSNY therapy alone (MD: 1.78, 95% CI 0.93-2.63, P<0.0001), nevertheless, no statistically significant results were found in melanin index (MI) and self-assessment. The melasma improvement was similar when using LQSNY alone and LQSNY combined with other lasers in terms of RMASI (MD 0.05, 95% CI:-0.61, 0.70, P=0.56). Compared to intense pulsed light (IPL) alone, LQSNY with IPL provided an added benefit for melasma severity (MD:3.23, 95%CI:0.65-5.81, P=0.01). CONCLUSION LQSNY can be applied as an alternative treatment for drug intolerance. Combination therapy with LQSNY and drugs or other lasers may have pleasantly surprising efficacy, but numerous studies are still needed to verify this.

Efficacy and Safety of Using Noninsulated Microneedle Radiofrequency Alone Versus in Combination with Polynucleotides for the Treatment of Melasma: A Pilot Study. Dermatol Ther (Heidelb) 2022; 12:1325-1336. [PMID: 35538360 PMCID: PMC9209614 DOI: 10.1007/s13555-022-00728-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Accepted: 04/08/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction This split-face, double-blind, randomized controlled study investigated the efficacy and safety of using a microneedling radiofrequency (RF) device with polynucleotides (PN) versus RF alone for the treatment of melasma. Methods Thirty adult participants with melasma (Fitzpatrick skin types III–V) received three treatments with an invasive, bipolar, pulsed-type microneedling RF device on both sides of the face. The treatment sessions occurred once every 2 weeks. The hemifaces of each participant were designated for treatment and control with PN and normal saline solution (NSS), applied after treatment with RF. Measurements were made of melanin index (MI), erythema index (EI), skin roughness (by the Antera 3D system), modified melasma area severity index (mMASI) for each hemiface, and patients’ self-assessed improvement. These occurred at baseline and again following the final treatment (2 weeks and 1, 2, 3, and 6 months after). Mean values were obtained for MI, EI, skin roughness, and mMASI. A generalized estimating equation (GEE) was used to compare the obtained values for the outcome measures across all assessment points. Results All patients were women (mean age, 43.2 ± 7.0 years). Mixed melasma predominated (61.5%; n = 16), and the mean duration of melasma was 8.9 ± 6.5 years. Twenty-six participants were followed up to the 6-month assessment point. Significant improvements were observed from baseline in MI, skin roughness, and mMASI scores for both the PN and control sides at 6 months, with no statistically significant differences between sides. Patients’ self-assessed improvement scores also showed a positive trend. Melasma recurrence was observed in three patients at 2, 3, and 4 months after the last treatment session (10% recurrence rate). Conclusions The combination of an invasive, bipolar, pulsed-type microneedling RF with PN is not superior compared with microneedling RF alone in the treatment of melasma. Microneedling RF may be considered as safe and efficacious for the improvement of skin roughness, and as an adjunctive treatment option for melasma. Clinical Trial Registration This study was registered on ClinicalTrials.gov and assigned NCT number TCTR20210804002.

Abstract
Objective: The study assesses the safety and efficacy of a 675-nm laser source on melasma. Background: Melasma is a frequent acquired skin disease defined by the presence of hyperpigmented macules on the face. Methods: Study protocol included up to three sessions of the 675-nm laser. Objective evaluation was assessed by using a 5-point visual analogue pain scale (VAS) (range, 0-4). Treatment tolerance was assessed using the 5-point VAS. Results: A mean 3.1 ± 0.7 improvement was reached according to photographic evaluation by VAS. Patients treated one time showed mean clearance of 3.3 ± 0.76, patients treated two times showed mean clearance of 3.0 ± 0.71, and patients treated three times showed mean clearance of 3.0 ± 1. Pain score mean was 1.2 ± 0.4. Conclusions: The 675-nm laser system seems to be safe and effective even in the treatment of facial melasma in patients with Fitzpatrick phototypes IV to V.

Abstract
The current study aims to evaluate the dependence of laser-induced optical breakdown (LIOB) on skin types by using 1064 nm picosecond laser with micro-lens arrays (MLA) and diffractive optical elements (DOE). Both black and white skin tissues were examined to comparatively assess the LIOB effects in the skin in terms of laser-induced vacuolization. The black skin irradiated at 3.0 J/cm2 demonstrated that MLA yielded a deeper distribution (180-400 μm) of laser-induced vacuoles with a size of 67 μm, compared to DOE (180-280 μm; 40 μm in size). However, the white skin presented that MLA created larger vacuoles (134 μm in size) in a smaller number at deeper distributions (125-700 μm) than MLA with the black skin. DOE generated no laser-induced vacuolization in the white skin. The white skin tissue with inherent higher scattering could be responsible for deeper vacuolization after the picosecond laser treatment. Further investigations are expected to determine the optimal treatment conditions for various skin types.

Abstract
Aging-associated dermatological pigmentary diseases are associated with accumulation of senescence cells and the disruption of basement membrane due to chronic ultraviolet radiation (UVR) exposure. Our study is on the synergistic effect of the novel 300 μm needle-depth fractional microneedling radiofrequency (FMR) treatment and conventional Q-switched ND:YAG laser on aging-associated hyperpigmentation of the skin. The prospective controlled clinical trial of 25 Asian women revealed significantly higher improvements not only on wrinkles, but also on hyperpigmentation. Additional ex vivo study revealed significant reduction of pro-melanogenic markers as well as senescent keratinocytes, while increased expression of collagen type IV on the epidermal basement membrane, after additional FMR treatment on UV-irradiated human tissues. These results demonstrate that 300 μm needle-depth FMR might effectively remove senescent keratinocytes that secrete pro-melanogenic markers, and repair disrupted basement membrane, therefore preventing constant hyperpigmentation of the aged skin.
