According to the American Association of Dermatology (AAD), acne is the most common skin condition in the United States, affecting up to 50 million Americans annually with a nontrivial percentage suffering from a chronic form of the condition. Fortunately, for people suffering from persistent acne, Paul M. Friedman, MD et al. showed in 2004 that near-infrared laser light could be used to damage the sebaceous glands causing them to shrink or in some cases be destroyed without damaging the skin. This particular gland is the one responsible for producing the oil which is metabolized by the bacteria during the inflammation process. While this procedure is not painless, the only side effects shown were temporary redness and swelling, which lead to the FDA approving the first commercially available acne treatment laser, the Smoothbeam by Candela a 1450 nm wavelength diode laser. Since then many other lasers in the 1400nm – 1500nm range have been approved by the FDA for the treatment of acne. In this blog post, we are going to take a look at the clinical requirements for laser acne treatment and how the current state of the art high power laser diode technology are utilized for treatment.
