Fig. 37From: Diagnosis and Treatment of Keloids and Hypertrophic Scars—Japan Scar Workshop Consensus Document 2018The ideal irradiation method of lasers. When performing laser therapy, the laser beam (arrows) should be held perpendicularly to the scar surface.

When irradiating the boundary of the scar (dashed arrows), it is permissible to irradiate some of the adjacent normal skinBack to article page
