Burns are injuries of skin or other tissue caused by thermal, radiation, chemical or electrical contact Clinically, treatment is challenging despite a wide array of options including corticosteroids, radiation, lasers and surgery. There have been several case reports of improvement in mature burn scars after treatment with fractional CO2 laser. Furthermore, burn scars are usually thick, wide and contracted, which may reduce the function of the anatomical region involved and result in deformity.
Background: Laser has become popular means of achieving hair reduction with improved quality of life. Meanwhile, different types of lasers show different clinical efficacy and safety according to the characteristic wavelength for each device and skin types of persons. Laser devices incorporating higher wavelengths have been developed to improve hair removal on dark skin, such as 1064 nm Neodymium-doped Yttrium Aluminum Garnet (Nd: YAG) laser. They not only provide deeper light penetration for targeting deeply located follicles but also allow for higher fluences to be used since absorption by melanin decreases when wavelength is increased and therefore the skin is heated less. This study aimed to assess the efficacy and safety of long-pulsed Nd: YAG laser on hair reduction. Methods: This study was carried out on 20 adult women who seek axillary hair reduction. These subjects were adjusted to receive 5 laser sessions with a 1-month interval. Clinical evaluation was done at 1 month after last session with detection of side effects of laser. Results: As regards Fitzpatrick skin type, 8 subjects (40 %) were skin type III and 12 subjects (60 %) were skin type IV. The hair count showed significant reduction (P<0.001) with hair reduction percentage of 64.3%. Regarding the side effects, there was significant pain during the procedure and encountered in 60% of cases. Conclusion: 1064-nm long pulsed Nd:YAG laser is safe and effective in hair reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
