This study reported that long-pulse alexandrite laser treatment achieved an overall hair reduction rate of 80.8% among patients, with minimal cases of hypo- or hyperpigmentation.

This study determined in-vivo skin damage thresholds for 1319-nm laser exposure in pigs, and the findings may enhance understanding of thermal damage mechanisms and inform laser safety standards.

This study found that laser hair removal is optimal for light to moderate skin tones using 10-15 J/cm² at 755 nm and for dark skin with 4.5-10 J/cm² at 755-1064 nm.

This study found that the maximum infrared temperature of laser-irradiated hair depends on melanin type, with eumelanin-rich hair reaching higher temperatures than pheomelanin-containing hair.

This review discusses various methods of light-based hair removal and reports no new clinical results, highlighting advances in laser and intense pulsed light technologies used for targeting hair pigmentation.

This review discusses the applications of the 308-nm excimer laser in treating various dermatologic conditions and suggests treatment is generally well tolerated, but calls for larger long-term studies.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

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 study evaluated an 808-nm diode laser at different fluences for permanent axillary hair removal in Korean women and found that high-fluence treatment (14 J/cm2) effectively reduced hair density and thickness, with no significant difference in comfort compared to lower fluences.

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.

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

This study found that long pulsed Nd-YAG laser treatment significantly improved acne keloidalis nuchae by reducing inflammation and hair follicles, with early intervention yielding the best results.

This study found that while both professional and home-use lasers effectively reduced axillary hair, the professional Diode laser was significantly more effective, achieving 85-88% reduction compared to 46-52% with the home-use laser, which still offers some safety for users.

This study found that ruby laser hair removal causes microscopic epidermal damage but does not lead to cellular hyperproliferation, unlike ultraviolet-irradiated cell damage.

In this study, a triple wavelength laser was found to be highly effective and well-tolerated for reducing hair in Indian women with Fitzpatrick skin types III and IV, achieving an average hair count reduction of 86.5%, with only mild and transient adverse effects observed.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This study found that Er:YAG laser treatment resulted in a statistically significant reduction in papules, plaques count, size, and consistency in men with acne keloidalis nuchae, showing slightly more improvement than long-pulsed Nd:YAG laser therapy.

This study concluded that the 800-nm diode laser is effective in enhancing skin structure and collagen expression via the TGF-β/Smad pathway, suggesting potential for non-ablative rejuvenation.

This article reviews the current use of lasers in hair restoration and reports no new findings, summarizing insights from doctors with laser experience.

This ex vivo study reported that a 645-nm wavelength red-light laser can penetrate and reach cells in the various layers of swine oral mucosa and periosteum tissue samples.

In this study, researchers found that specific treatment parameters disrupted follicles and sebaceous glands, damaging the bacteria Cutibacterium acnes and promoting follicular remodeling, which may improve both inflammatory and noninflammatory acne lesions.

This study found that blue laser irradiation reduced ATP levels and cell viability in mouse skin by increasing oxidative stress through the production of reactive oxygen species.

This study found that pulsed infrared diode laser therapy (904 nm) was effective in promoting hair regrowth in 94% of patients with resistant patches of alopecia areata.

This study found that photodynamic therapy achieved permanent removal of nonpigmented hair in mice after multiple sessions, unlike laser treatment, which was not effective for nonpigmented hair.

This study found that the Epilight multiple wavelength pulsed-intense light source was effective for long-lasting hair removal, particularly in individuals with dark hair and light skin.

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.

In this study, the P&P Hairline Laser, a hands-free laser-assisted device, was found to produce smoother and more symmetrical hairlines compared to traditional handheld laser devices.

This abstract contains no research results; it provides information about the JAMA Dermatology journal and its access options.

The study's findings are unreliable due to retraction.

This study found that low power He:Ne laser and methylene blue successfully damaged hair follicles in mice while preserving the epidermis, suggesting a potential for improved long-term hair removal options.
