Treatments may vary from 15 to 35 minutes depending on the size of the area to be treated. First, the treated area is cleansed and a cool gel is applied. When the pulse of light is delivered, the sensation is similar to a snap of a rubber band. After treatment, the gel is removed, the skin cleansed, and a sunscreen is applied. Topical anesthesia can be used for maximum comfort. For sensitive skin, a cool compress is applied following treatment.
