Picosecond laser pigment evidence for Melasma (mixed / dermal)

Abstract summary (English) OBJECTIVES: This randomised controlled trial aimed to compare the efficacy of Alexandrite picosecond laser therapy combined with dermal polyrevitalisation (NCTF® 135 HA) with laser therapy alone for reducing the severity of melasma. The outcomes were assessed using 3D imaging and the Dermatology Life Quality Index (DLQI). The secondary objectives were to evaluate the safety and tolerability of the combined...

Comparative Study, Journal Article, Randomized Controlled Trial

Abstract summary (English) Melasma is a chronic hyperpigmentation disorder that disproportionately affects women and individuals with darker skin types, leading to a significant psychosocial burden. This meta-analysis aims to evaluate the safety and efficacy of the 755-nm picosecond alexandrite laser (PSAL) compared with conventional therapies in the management of melasma.

Abstract summary (English) PURPOSE: Melasma remains a refractory skin condition that needs to be actively explored. Azelaic acid has been used for decades as a topical agent to improve melasma through multiple mechanisms, however, there is a lack of research on its combination with laser therapy. This study evaluated the effectiveness of isolated treatment with topical 20% azelaic acid and its combination with 755-nm picosecond laser in...

Abstract summary (English) BACKGROUND: Melasma is a refractory pigmentary disorder. The picosecond Nd:YAG 1064-nm laser (PSNY) has promise as a better treatment for melasma with few side effects and favorable therapeutic efficacy. The authors evaluated the efficacy and safety of PSNY and the nanosecond Q-switched Nd:YAG 1064-nm laser (QSNY) in patients with melasma.

Randomized Controlled Trial, Journal Article

Abstract summary (English) BACKGROUND: While combined laser and topical treatments are currently a common approach to melasma treatment, data on the efficacy and safety of this combined therapy remain scarce, with studies showing varied results. OBJECTIVE: To compare the efficacy and safety of hydroquinone (HQ) cream alone versus HQ cream combined with 755-nm picosecond (PS) laser in the treatment of melasma. METHOD: Twenty subjects...

Randomized Controlled Trial, Case Reports, Journal Article

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...

Journal Article, Randomized Controlled Trial

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: Acquired dermal melanocytosis (ADM) is a pigmentary lesion caused by melanocytes in the dermis. These conditions are refractory, and a consensus on treatment remains elusive. AIMS: To compare the efficacy of 730- and 1064-nm picosecond lasers in the treatment of ADM and to supplement the comparison with a literature review.

Journal Article, Comparative Study

Abstract summary (English) BACKGROUND: Melasma is a therapeutically challenging hyperpigmented skin condition. Currently, there is a lack of in vivo observation regarding changes in melanin and dendritic melanocytes after laser treatment. OBJECTIVE: To investigate alterations in melanin and melanocytes in melasma before and after laser treatment using optical coherence tomography (OCT).
