Red-light therapy in recalcitrant acne - a case series

The use of various light sources is being increasingly tried in various dermatological conditions like acne, skin rejuvenation, and chronic ulcers to name a few. Red-led light therapy (633nm) is a cost-effective and simple procedure that gives promising results, especially for the inflammatory type of acne vulgaris. In this case series, we present three patients with inflammatory acne who were non-responsive to most of the anti-acne therapy but responded dramatically with red-led light therapy.
