Picosecond laser pigment evidence for Melasma (epidermal)

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) Low-fluence picosecond (LFPS) neodymium-doped yttrium aluminum garnet (Nd: YAG) 1064 nm laser has emerged as a promising treatment for melasma; however, its optimal strategy remains unclear. To evaluate the efficacy and safety of LFPS combined with microlens arrays (MLA) compared with LFPS alone in treating melasma. Thirty patients with melasma received LFPS alone on one side of the face (control [C] side) and LFPS...

Journal Article, Randomized Controlled Trial

Abstract summary (English) This study aimed to evaluate the clinical efficacy of picosecond laser therapy combined with the Shumin Star in treating melasma and to explore the role of skin barrier function indicators in the assessment of this treatment process. Ninety patients with melasma were randomly divided into a study group and a control group. The study group received picosecond laser therapy combined with the Shumin Star, while the...

Journal Article, Randomized Controlled Trial

Abstract summary (English) Melasma significantly impacts life quality, and while various laser therapies show promise, rigorous comparative studies, especially between the novel Picosecond Alexandrite Laser (PSAL) and the traditional combined modality of Q-switched and Long-pulse Nd: YAG Lasers (QLNYL), are notably lacking. This study aims to fill this gap by evaluating the efficacy and safety of these modalities, providing insights into...

Journal Article, Randomized Controlled Trial, Comparative Study

Abstract summary (English) BACKGROUND: The picosecond 755-nm alexandrite laser and topical tranexamic acid (TA) have shown promise in treating melasma. AIM: This aim of this study was to evaluate the efficacy and safety of combining to a picosecond 755-nm alexandrite laser combined with topical TA for melasma treatment. PATIENTS AND METHODS: Forty-eight patients' facial halves with bilateral symmetrical melasma were randomized to receive...

Journal Article, Randomized Controlled Trial

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...

Journal Article, Randomized Controlled Trial, Comparative Study

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...
