Laser au thulium pour les cicatrices d'acné : fonctionnement de la longueur d'onde de 1 927 nm, preuves cliniques & Guide de traitement
A 1927nm thulium laser treats atrophic acne scars by creating controlled micro-columns of thermal injury in the epidermis and papillary dermis, triggering collagen remodeling with 3-5 days of downtime. Split-face studies show fractional thulium laser results comparable to Er: YAG for acne scars, with less pain and faster recovery — most patients need 3-5 sessions
