Wrinkles and acne scars: Fractional ablative lasers

Abstract

Fractional ablative lasers create columns of ablated tissue separated by zones of intact tissue, resulting in rapid re-epithelialization and induction of new collagen production. Fractional ablation provides a greater margin of safety compared to conventional laser ablation by avoiding the production of open wounds. Fractional ablative lasers improve photodamage and scars in one to two treatment sessions. © 2011 Springer-Verlag Berlin Heidelberg.
