Summary

Keratosis pilaris (KP) is a common disorder of keratinization. There are different treatment modalities for KP with variable results. Nd:YAG laser and chemical peels are among these treatment modalities, however, there is no enough evidence in the literature regarding their efficacy. The aim of this study is to assess and compare the efficacy of long pulsed Nd:YAG laser and trichloreacetic acid 20% in treatment of keratosis pilaris.

Description

Keratosis pilaris (KP) is a genetic disorder of keratinization of hair follicles of skin. It's a very common benign condition that manifests as small, rough folliculocentric keratotic papules, often described as chicken bumps, chicken skin or goose-bumps, in characteristic areas of body, particularly the outer upper arms and thighs.

Trichloreacetic acid (TCA) is a type of chemical peels that is derived from acetic acid by the chlorination of 3 hydrogen ions. It can induce coagulative necrosis of proteins and cells. The depth of action depends on various factors e.g the number of layers applied and its combination with substances that potentiate its action.

Nd: YAG laser is a type of hair removing devices that operates at wave length of 1064nm. This wave length allows for less absorption at the epidermis. It is less absorbed by melanin, which leads to lower side effect and better tolerance but less efficacy in dark skinned patients.
