Using Light to Treat Acne

Have you heard about photodynamic therapy? It has been getting a lot of press lately regarding its success as an acne treatment. Although it's not a brand new procedure, there have been great advances in the past few years making it a viable treatment option for acne.

Photodynamic therapy (PDT) isn't a laser treatment, but rather uses ultraviolet light to help clear acne blemishes. It's thought to shrink oil glands, reduce acne-causing bacteria, and can also improve the texture of the skin.

While the procedure isn't cheap, and unfortunately isn't often picked up by insurance, more adults are turning to photodynamic therapy especially after getting lackluster results with topical treatments. As an added bonus, PDT may also diminish surface acne scars and age spots.
