Home-use laser and light devices for the skin: an update.

Over the past several years, a number of home-use laser and light skin devices have been introduced for various indications, including photorejuvenation, hair growth, hair removal and acne treatment. Although these devices allow for privacy and a significant cost advantage, they are typically underpowered and afford lower efficacy than their in-office counterparts. A number of these devices have recently received FDA clearance. Although large clinical trials are lacking, dermatologists should familiarize themselves with the various options to help patients assess their clinical value.
