This study found that Argireline significantly reduced the depth of periorbital wrinkles in Chinese subjects and improved skin morphology in aged mice.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

This literature review reported that fractional lasers, like the 1550-nm nonablative erbium-glass laser, may enhance hair regrowth by stimulating a wound healing process, but more randomized controlled trials are needed to confirm their effectiveness and optimize treatment parameters.

The laser comb did not improve hair regrowth in mice with alopecia areata.

Lasers in hair transplantation show promise but are not yet standard, with current methods causing some side effects and needles still being preferred for creating recipient sites.

This letter to the editor discusses an unusual complication, crescent-shaped incisional cuts, observed with Q-switched Nd:YAG 1064 laser tattoo removal and reports no new clinical results.

This study reviews the mechanism and potential treatment roles of low-level laser therapy for immune-mediated skin diseases, reporting no new clinical results.

This report describes two cases of extensive alopecia areata successfully treated with a combination of intralesional corticosteroids and fractionated laser, suggesting the potential of laser treatment to promote hair regrowth.

This study reviewed clinical trials and found that low-level laser therapy significantly increased hair diameter or density in both men and women with pattern hair loss compared to a sham device, though the involvement of industry relationships in some studies suggests cautious interpretation.

Most transgender patients getting laser hair removal before gender-affirming surgery are already on hormone therapy, which might affect the hair removal process.

This review highlights the various cosmetic and therapeutic applications of laser technologies in dermatology, discussing the mechanisms, safety, efficacy, and recent advancements to provide a comprehensive overview of their uses and potential future implications.

This study found that 1,540 nm fractional erbium-glass laser treatment combined with topical minoxidil significantly increased hair regrowth in alopecia areata patches compared to minoxidil alone, with response rates of 60% versus 16%, though the long-term effects remain unknown.

This review assesses low-level laser therapy in plastic surgery and reports that it may improve flap survival and burn scars, but lacks efficacy for venous ulcers, alopecia, and skin aging.

This article reviews the characteristics and distribution of alopecia areata and reports no new clinical results.

This study found that low-level laser treatment with the HairMax Lasercomb significantly increased terminal hair density in both men and women with pattern hair loss, with no serious adverse events reported.

This study concluded that ablative fractional lasers may induce hair regrowth in mice by activating the Wnt/β-catenin pathway.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This study reported that a new laser scanner using 655 nm red and 808 nm infrared lasers significantly improved hair density in patients with androgenic alopecia compared to both a laser hat and no treatment, without observable adverse effects.

This study found that using a ruby laser for hair removal resulted in a significant average reduction of 56.4% in hair density among participants dissatisfied with other methods.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

This study observed hair regrowth and increased density in four cases of androgenetic alopecia treated with a non-ablative erbium glass fractional laser and topical finasteride, with no significant side effects reported.

This study found that low-level laser treatment may promote hair regrowth in mice by activating the Wnt10b/ß-catenin pathway and inducing the anagen phase of hair follicles.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

In this study, low-level light therapy using a new helmet-type device significantly increased hair density and thickness in patients with androgenetic alopecia, showing no adverse events or side effects, suggesting it may be a safe and effective treatment option for both sexes.

LLLT is a safe, promising hair loss treatment, but more research needed.

This study observed that persistent urticaria is a rare side effect of laser epilation, potentially linked to a hypersensitivity reaction in patients with allergies.

In this study, both 1565-nm non-ablative fractional laser and long-pulsed 1064-nm Nd:YAG laser effectively reduced enlarged facial pores, with no significant difference in efficacy and minimal side effects, though the Nd:YAG laser had less severe side effects.

This review highlights recent advances in laser treatments for skin disorders, including the optimization of vascular lesion treatment and improved safety for hair removal, but reports no new results.
