Fractional picosecond resurfacing evidence for Melasma (epidermal)

Abstract summary (English) OBJECTIVES: Pulsed laser treatment of melasma has shown some promising results. To compare the effectiveness and safety of 755-nm picosecond alexandrite laser (PSAL) fitted with diffractive lens array (DLA) versus 1064-nm Q-switched neodynimum:yttrium aluminum garnet laser (QSNYL) for the treatment of melasma. METHODS: We conducted a randomized, split face controlled, 2-year follow-up study.

Abstract summary (English) 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...

Abstract summary (English) Melasma is a highly prevalent and cosmetically disfiguring pigmented skin disease. The post-treatment results are often unsatisfactory. A large number of clinical trials have tried to prove the effectiveness of the combination therapy involving laser therapy, but the results have been indeterminate.

Journal Article, Meta-Analysis, Systematic Review

Abstract summary (English) Background: Melasma is an acquired pigmentation disorder with challenges in treatment because of its refractory nature and high risk of recurrence. Objectives: This study aimed to compare the efficacy and side effects of 14 common therapies for melasma using a systematic review and network meta-analysis (NMA). Methods: The PubMed, Embase, and Cochrane Library databases were searched till...

Systematic Review, Journal Article

Abstract summary (English) BACKGROUND AND OBJECTIVES: Treatment of melasma with lasers remains a challenge due to its limited clinical efficacy in addition to high rates of recurrence and side effects. Recently, picosecond lasers have shown favorable results in treatment of benign pigmented lesions. To compare the efficacy and safety of using a 755-nm picosecond laser for the treatment of melasma in a split-face manner, having one side...

Abstract summary (English) BACKGROUND: Recent evidence suggests melasma to be a photoaging disorder. Triple combination creams (TCC: fluocinolone acetonide 0.01%, hydroquinone 4% and tretinoin 0.05%) remain the gold standard treatment. Picosecond alexandrite laser treatment using a diffractive lens array (DLA) has been identified to be effective for improving photoaging conditions.

Abstract summary (English) BACKGROUND: Picosecond laser is a novel modality for pigmented skin disorders with extremely short pulse duration. Little is known about the effects of the picosecond laser in melasma. OBJECTIVE: This study aimed to investigate the efficacy of fractional picosecond 1,064 nm laser in melasma treatment.

Journal Article, Randomized Controlled Trial

Abstract summary (English) BACKGROUND: Picosecond lasers appear to be effective and safe in treating pigmentation and photoaging disorders through laser-induced optical breakdown. OBJECTIVE: To analyze the feasibility of photorejuvenation using picosecond lasers with diffractive lens array (DLA) in patients with melasma. METHODS: Ten Asian (N = 10) women with melasma and Fitzpatrick skin Type IV were enrolled and treated using 755-nm...

Journal Article, Observational Study

Abstract summary (English) BACKGROUND/OBJECTIVES: The picosecond Alexandrite laser was studied in our practice with the diffractive lens array and the flat optic to treat melasma. METHODS AND MATERIALS: Sixty patients with melasma were treated in a prospective investigation with the picosecond Alexandrite laser. Nineteen patients were treated with the flat optic and 41 patients were treated with the diffractive lens array.

Clinical Trial, Journal Article

Abstract summary (English) Melasma is a chronic acquired hyperpigmentation disorder that often exerts a psychosocial burden on affected individuals. Although laser- and light-based therapies are pivotal third-line interventions for recalcitrant cases, clinical consensus regarding their comparative efficacy and long-term safety remains inconsistent. This systematic review and meta-analysis aimed to evaluate and synthesize evidence from...
