THE EFFECTS ON THE SKIN OF A NEW FRACTIONAL LASER. MACROSCOPICAL AND HISTOLOGICAL EXAMINATION

摘要

Fractional resurfacing is an exciting new technology that fills a unique niche in any skin care rejuvenation protocol. "Fractional Photothermolysis" seeks to only damage certain zones within the selected target area, (producing tiny dot, or pixel-like treated areas on the skin), leaving the other zones within it perfectly intact; hence only causing fractional damage through the heat of the light source. This allows the skin to heal much faster than if the whole area was treated, as the 'healthy' untreated tissue surrounding the treated zones helps to fill in the damaged area with new cells. The Authors examine the effects of this new procedure on the skin, with the aim of analyze the treatment, exploring the cutaneous reaction to various laser pulse durations and energies by means of the macroscopic reaction and histological appraisal.
