[Lasers and aesthetic dermatology]

Abstract

The improved understanding of laser-tissue interaction along with the latest advances of laser technology have led to the development of sophisticated, safe, and user-friendly laser systems that provide effective treatment for a variety of aesthetic skin conditions. The use of lasers and their tissue-specific capabilities in the treatment of pigmented and vascular lesions has been greatly expanded to include rhytides, photoaged skin, atrophic scars, and unwanted hair. In addition, laser techniques have been employed in traditional "rejuvenating" procedures of aged skin, e.g., face-lifting, blepharoplasty, and hair transplantation, decreasing the intra-operative time and limiting the recovery period. These advances have led to a wide acceptance of cutaneous laser surgery by the dermatologic community and have created an increasing popularity among the public. The purpose of this article is to review the applications of lasers in aesthetic dermatology and discuss their limitations and potential side effects.
