In addition to treating tattoos and pigmented lesions, new picosecond devices also treat sun damage and scarring. The results achieved by picosecond lasers are due to photothermal as well as photomechanical effects. Picosecond pulse duration lasers have an excellent safety/side effect profile in individuals of all skin types.
Scientific findings indicate that people need to do more to protect their skin from the sun and must now also begin thinking about the damaging effects of exposure to pollution. Topical applications of antioxidants and DNA repair enzymes have potential to be helpful tools, according to an expert who spoke at the 2014 Annual Meeting of the American Society for Dermatologic Surgery.
