Laser hair removal alexandrite ndyag evidence for Darker skin (Fitzpatrick IV-VI)

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) 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...

Abstract summary (English) IMPORTANCE: Hirsutism represents a significant concern for women with polycystic ovary syndrome (PCOS), with deleterious psychological effects warranting acknowledgment and a clear imperative to provide effective management. To our knowledge, this is the first review to exclusively examine the effectiveness of laser and light-based therapies in addressing hirsutism in women with PCOS. OBJECTIVE: To synthesize the...

Abstract summary (English) BACKGROUND: Laser hair removal is associated with moderate acute pain. OBJECTIVE: To compare effectiveness of ice pack to topical lidocaine-prilocaine for pain reduction during axillary laser hair removal. METHODS: Participants were randomly assigned to receive topical anesthetic to one axilla and ice packs to the other before each of 3, monthly 810 nm diode laser sessions.

Randomized Controlled Trial, Journal Article

Abstract summary (English) BACKGROUND AND OBJECTIVES: The 1064 nm wavelength is optimized for dark skin, but within the range of available fluences for commercially available 1064 nm devices, may not provide effective treatment for lighter hair. The 755 nm alexandrite wavelength can treat a full range of hair colors but is not ideal for darker skin. The hypothesis is that a new laser system capable of emitting 755/1064 nm wavelengths...

Abstract summary (English) Despite multiple individual studies proving efficacy of grid fractional monopolar radiofrequency (Grid RF) and near-infrared irradiation 1064-nm long-pulsed neodymium:YAG laser (Laser Genesis), there is a lack of controlled comparative trials between these devices. This study aims to compare the efficacy and safety of Grid RF versus Laser Genesis in the treatment of periorbital rhytides. This is a randomized,...

Abstract summary (English) Lasers are considered the most efficient methods for hair reduction. The goal of these devices is to provide long-term effects without adverse reactions. This is a randomized split-body controlled study on body hair removal and pseudofolliculitis (PFC) treatment, comparing the standard single pass (SP) emission with the multipass emission (Moveo handpiece) with 755 alexandrite laser.

Journal Article, Randomized Controlled Trial

Abstract summary (English) Light-based therapies are one of the most effective and widely used strategies for removal of undesired hair, with a broadly favourable safety profile. However, subjects with pigmented skin are found to be more prone to laser-related adverse events. While prolonged pulse-width and longer treatment duration were proposed to minimize adverse events, the optimal treatment option among available phototherapy modalities...

Journal Article, Meta-Analysis, Systematic Review

Abstract summary (English) Background: Novel protocols are evolving to enhance hair follicle damage while preserving safety and improving efficacy. Objectives: The safety and tolerability of a 755-nm diode laser was compared to a combined laser with topical photo-enhancer gel ("combined") versus laser alone ("solo"). Methods: Twenty women (age 23-33 years old), Fitzpatrick skin type I-V, were randomized to side-by-side...

Journal Article, Randomized Controlled Trial

Abstract summary (English) BACKGROUND AND OBJECTIVES: There are no large volume comparative studies available to compare the efficacy of lasers over lights for hair removal in Fitzpatrick V and VI skin types. This study is designed to compare the efficacy of Nd:YAG laser versus IPL in the darker skin types. STUDY DESIGN/MATERIALS AND METHODS: Thirty-nine patients included in Group-1 were treated with Nd:YAG and 31 in Group-2 with IPL.
