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.

In this clinical study, low-level laser therapy using the HANDI-DOME LASER device increased hair counts by 51% compared to controls, indicating its potential as a safe and effective treatment for androgenetic alopecia in women aged 18 to 60.

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.

This review suggests that paradoxical hair growth after light-based treatments is unlikely due to the devices themselves; instead, it may be linked to other factors such as inflammation in individuals with certain conditions.

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.
