Is photodynamic therapy effective for acne?

PDT tends to be more effective for inflammatory, rather than non-inflammatory, acne. Another important benefit of photodynamic therapy is that it does not involve the use of antibiotics or oral retinoids, such as Accutane. This makes PDT a viable treatment for people who cannot take those medications.

PDT may be especially beneficial for people with severe acne or those whose acne has not responded well to other treatments.
