Abstract
Summary Classical, ablative laser resurfacing has proven to be very effective for skin rejuvenation, but ablative treatments are associated with significant side effects and down-time. The introduction of newer non-ablative optical methods has generated much interest during the last few years due to very few side effects and low post-operative morbidity. Non-ablative skin rejuvenation is a series of different optical treatment modalities, which operate through different biological pathways to achieve the following objectives: 1) reduction of visible vessels, 2) reduction of uneven pigmentation, and 3) increased synthesis rate and remodeling of collagen in the upper dermis leading to reduced wrinkling of the skin surface. This paper describes different non-ablative laser-, intense pulsed light and LED technologies for non-ablative treatments of photo-aged skin.
