title: [Laser applications in dermatology].
abstract: Argon laser, dye-, carbon dioxide- and Neodymium YAG laser are the most widely used in dermatological practice. The primary usage for argon- and dye lasers are vascular lesions. 60 to 70% of adult patients with port-wine nevus are successfully treated. Vascular lesions give the better results, when treated by a dye laser. Adverse side effects are minimal. After argon laser treatment adverse side effects like hyper- and hypopigmentation (-17%), atrophy and scars (4 to 5%) are observed. Carbon dioxide laser can be used to treat benign and malignant tumors of the skin. Tattoos can be removed by argon laser. Carbon dioxide- or neodymium YAG laser. The cosmetic result is not optimal for all the three laser systems. Neodymium YAG lasers can be used for the treatment of benign and malignant skin tumors in difficult areas and older patients. But the results are not better than with other procedures. Controversial results have been published concerning a phenomenon known as "biostimulation" caused by helium-neon laser. Rational indication for this laser treatment cannot be recommended in the moment.
