Evaluation of the response and healing effect after laser hair removal using a multi-spectral dermatoscope

A multi-spectral dermatoscope was used to investigate the effect of laser hair removal. Ten volunteers underwent three laser treatments, 6 weeks apart. In a subsequent trial, three volunteers received one laser treatment after which the skin region was imaged at short intervals. Practical solutions were developed to re-locate the investigated skin area. After exact matching using rigid and elastic registration software, the images showed acute and delayed effects on the hairs, pigment and vasculature after laser hair removal and subsequent healing response. The multi-spectral dermatoscope provides a perfect tool to study the efficacy and side effects of laser hair removal procedures and can be used to optimize the treatment plan.
