What Is It?
Ablative fractional lasers shine an intense beam of light at the skin in a dot-matrix (imagine tiny polka dots) pattern. The light completely removes (ablates) the epidermis in this dot-matrix pattern, leaving some of the skin intact. It also stimulates the underlying dermis to produce more collagen and elastin over time. Ablative fractional lasers attempt to approximate the efficacy of ablative lasers while not completely removing the entire surface of the skin, thus reducing side effects.
