Over the past few years, lasers have become popular tools for removal of unwanted hair.1- 3 Both patients and physicians have noted the somewhat serendipitous reduction in the intensity and number of pigmented lesions in hair-bearing areas following laser hair removal. Considering that lasers designed for hair reduction use wavelengths that target melanin in the hair shaft, it seems reasonable that superficial pigmented lesions would lighten in color.
