What this Trial Is About
Keratosis pilaris (KP) is a very common skin condition that affects up to 80% of adolescents and 40% of adults. Clinically, KP causes rough dry patches and tiny spiny bumps around the hair follicles, as well as redness and pigmentation changes, most often on the upper arms, thighs, cheeks, or buttocks. While KP is benign, it can be cosmetically very bothersome. Currently, treatment options for KP are limited, and consist of topical moisturizers and keratolytic agents, but often leads to suboptimal improvements. In literature, many laser treatment modalities for KP have been studied, with varying results. The primary aim of this pilot study is to investigate how KP, a predominantly follicular disorder, responds to treatment with the 1927-nm Thulium laser.
