Use of Noninvasive Methods in Evaluating Different Treatments of Psoriasis and the Effects of UV Exposure on Normal Skin

Abstract

In this article I will review and comment on two studies which exemplify the use of different noninvasive methods in clinical dermatology research. In one of the studies we followed the healing of psoriasis and evaluated two slightly different treatments. In the other we followed the effect of a single exposure of ultraviolet light on normal skin. The methods used were evaporimetry, laser-Doppler flowmetry, and optothermal infrared spectrometry (OTIS).
