Many options are available to treat acne, the most common of which are topical medications and antibiotics. Light-based therapies such as pulsed light are newer forms of treatment that reach deep layers of skin without harming the skin's surface.
The Problem
Sebaceous glands in the skin produce an oily substance called sebum. When excessive amounts of oil occur, common in adolescence, it prevents dead skin cells from shedding. The cells accumulate and develop into plugs in the pores. Bacteria cause additional inflammation.
Identification
Pulsed green-yellow light is combined with pulsed heat energy to treat mild to moderate acne, including inflammatory acne.
Function
This combination therapy destroys the bacteria that cause acne and shrinks sebaceous glands, thus decreasing sebum production. The therapy has been approved by the U.S. Food and Drug Administration and shows promise, according to the Mayo Clinic.
Expert Insight
Researchers saw significant improvement as early as four weeks after pulsed light therapy treatments at two per week, according to the American Academy of Dermatology. The treatment is effective for inflammatory and noninflammatory acne.
Side Effects
Side effects of pulsed light acne therapy are mild, with temporary redness in the areas of treated skin.
