Lasers in dermatology.

Laser technology, since its inception, has grown to find it's in varied fields, and medical science has been no exception. Dermatological surgery is in itself an emerging field in medical science, and the evolution of laser technology has further widened its scope, with various therapeutic well as diagnostic applications. Though the use of this technology is rapidly evolving, controlled studies to compare the efficacy of different types of lasers in specific skin conditions, or its effect on different skin types, is lacking. This study presents the observations of the response to the Carbon-di-oxide laser used to treat various skin conditions, in the Nepali skin phenotype. Lasers are being used to treat a wide variety of dermatological conditions, many of which did not have satisfactory treatment in the past. Further studies are required to study the effect of lasers in the Nepali skin phenotype, so as to standardize the wavelengths, doses and exposure times that would be suitable to treat specific skin conditions.
