New light therapy could zap precancerous skin spots on Hard-to-Treat areas
Disease control CompletedThis study tests a gel (Ameluz®) plus red light therapy for actinic keratosis, rough precancerous patches on skin. It includes 172 adults with 4-15 spots on arms, legs, neck, or trunk. The goal is to see if the treatment clears these spots better than a placebo gel.

Can a shorter gel wait time still clear precancerous spots?
Disease control CompletedThis trial tests whether a lower-strength light-activated gel (8% vs. 16%) and a shorter wait time before red light treatment (1 hour vs. 3 hours) can effectively clear actinic keratoses—rough, precancerous spots caused by sun damage—on the face. Participants will receive one of …
