Abstract
Lasers have many applications in dermatology. Recent developments in laser technology have produced significant therapeutic advances in several areas. The introduction of pulsed tunable dye lasers has considerably improved the treatment of vascular lesions, particularly port wine stain malformations in children. A wider range of continuous-wave and quasi-continuous-wave lasers have also become available for treating vascular lesions, and their use in conjunction with automated delivery systems has improved results whilst reducing adverse effects. Increasing interest in treatment of pigmented lesions and tattoos has led to investigation of a range of high-power short-pulse lasers, and early results look very promising. However, further work is needed in all these areas to determine which lesions respond best to each laser system, and which treatment techniques are optimal.
