Light therapy for moderate to severe acne
Part of Skin clinical trials.
This trial tests a light-activated therapy (called photodynamic therapy) using a special gel that is put on the skin and then activated with a light to treat moderate to severe acne. It may help people who have not responded well to other treatments.
