Ablative Laser Therapy of Skin.

Laser skin rejuvenation was introduced in the mid-1990s. Early ablative laser devices relied on scanner technology that provided significant ablation and longer time on tissue treatments. These early treatments provided significant improvement in the appearance of the skin, but because of the longer treatment times and in some cases excessive treatment, complications such as scarring and hypopigmentation were significant. More recent advances in skin resurfacing technology have now minimized these risks providing certain key principles are observed. These parameters are reviewed in detail to improve the reader's ability to propose and execute proper skin resurfacing treatments.
