Laser treatment is safe and can effectively treat toenail fungus, especially when combined with other treatments if no improvement is seen after about a year.

This study found that combining fractional erbium-glass laser therapy with topical minoxidil significantly improved hair density and diameter in men with androgenetic alopecia compared to using minoxidil alone over a 24-week period, with no serious adverse events reported.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

This review discusses five popular resurfacing technologies for facial rejuvenation, highlighting their role in achieving smoother, healthier, and younger-looking skin, and reports no new clinical results.

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.

This article reviews the growing trend of at-home laser and light devices for treating conditions like acne, hair removal, and psoriasis, emphasizing their popularity and the need for cautious use but reports no new clinical results.

This review summarizes late-breaking abstracts from the American Society for Laser Medicine and Surgery, 2018, and reports no new clinical findings.

In this experimental study, laser irradiation significantly altered the gene expression of cytokines in cultured human T-cell lymphocytes, suggesting that such laser light may photobiomodulate cytokine production in vitro.

This article reviews the use of the Nd:YAG laser for hair removal and reports no new research findings.

This study found that the long-pulse Nd:YAG laser effectively reduces unwanted facial hair across various skin types, with hair regrowth delayed significantly longer than with self-applied methods.

This study found that cold air can effectively preserve the epidermis when using an 810 nm diode laser, but it is slightly less effective than a chilled sapphire window in dark-haired pigmented pigs.

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.

This literature review suggests that fractional laser therapies may positively impact hair regrowth in androgenic alopecia, though current evidence is mostly limited to small studies and case reports, highlighting a need for more comprehensive randomized controlled trials to confirm their efficacy and safety.

This case report describes the first use of photobiomodulation therapy with a continuous wave red laser (660 nm) as monotherapy for alopecia areata, resulting in significant hair regrowth within 7 days, though further research is needed for conclusive evidence.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

This study found that a combination treatment of laser photobiomodulation and plasma jet therapy was effective in improving alopecia areata in a 38-year-old woman after 14 sessions over three months, as evidenced by comparative photo documentation.

This study investigated the effects of 10600nm CO2 dot laser and Nd: YAG laser on Wistar rats' skin, finding that CO2 laser treatment resulted in higher positive expression of MMP-1 and TIMP-1 compared to Nd: YAG laser, with statistically significant differences noted.

This case report suggests that 1064 nm picosecond Nd:YAG laser therapy may effectively improve alopecia totalis when used as an alternative adjuvant treatment, as demonstrated in a split-scalp study showing better results than steroid treatment alone.

This article shares the authors' experiences with the erbium YAG laser in hair restoration surgery, noting improved graft yield and reduced thermal damage compared to traditional methods.

This review discusses the factors affecting laser hair removal results and adverse events, emphasizing the need for more research to determine optimal treatment parameters; it reports no new clinical findings.

This study compared the microscopic treatment zones created by different fractional lasers and radiofrequency in swine skin, finding distinct patterns and damage levels for each technology.

This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.

This review discusses home-use laser and light skin devices for various dermatological purposes and reports no new clinical findings; the authors highlight the need for dermatologists to evaluate these devices' clinical value.

This review highlights that laser and light treatments could serve as safe and effective alternatives to current therapies for alopecia areata, with the excimer laser showing positive results, though further randomized controlled trials are necessary to establish optimal treatment protocols.

In this study involving 13 patients with vitiligo-associated leukotrichia, minimal hair repigmentation was observed following treatment with fractional CO₂ laser and topical betamethasone, though the method was well tolerated, highlighting the need for further research to optimize treatment parameters.

This study found that low-level light therapy significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, suggesting it could be an effective treatment option.

This article reviews patient selection and treatment protocols for various light-based hair removal systems but presents no new clinical results.

This review details the advancements and benefits of fractional erbium:YAG resurfacing lasers for treating photoaging, acne scarring, and dyschromia, but it presents no new clinical results.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This review discusses laser-assisted drug delivery for enhancing topical treatment efficacy in various dermatological and medical applications but reports no new clinical results, emphasizing the need for further research to optimize its use.
