title: Update dermatologic laser therapy.
abstract: New trends in dermatological laser therapy during the last years are based on new wavelengths, concepts and treatment combinations resulting in a variety of new dermatologic indications. Fractional laser therapy of chronic actinic damage of the skin has been introduced and already represents a standard technique. The concept of fractional non-ablative and ablative laser treatment has been shown to be safe and effective. Also pigmented and vascular skin changes can be treated by this method. New, very promising concepts for laser epilation include linear scanned as well as low fluence laser systems. The first enable very short treatment times for large areas; the latter are the basis for the growing market of laser epilation devices for home use. Nevertheless, the potential of low fluence laser devices for long-term hair reduction has not been tested so far. Furthermore, no data exist on side effects resulting from repetitive application of laser light to melanocytic lesions. Laser lipolysis has been introduced as the latest, minimally invasive way of removing small localised fat deposits. The new procedure may have a great potential for liposculpture; its further development should be thoughtfully observed. The latest innovations for precise ablation are ultra-short pulsed laser systems. Femtosecond lasers avoid thermal damage at the border areas of ablation zones.
