A novel explanation for the healing effect of the Er:YAG laser during skin rejuvenation

Abstract

The popularity of cutaneous laser resurfacing has soared in recent years. Ablative laser skin rejuvenation with carbon dioxide (CO₂) and erbium:yttrium-aluminum-garnet (Er:YAG) lasers has been popularized and their side effects individually reported. It has been suggested that initial collagen contraction and thermal damage modulate wound healing. Progress in laser technology permits precise tissue removal and minimal thermal damage. However, mechanisms for cosmetic improvement have not yet been completely determined. In the present short communication, we would like to suggest a possible mechanism for the healing effects exerted by the Er:YAG laser.
