Acne is a very common inflammatory reaction in the oil-producing follicles of skin. The problem may affect people of any age and accounts for 25 percent of all visits to dermatologists. Patients with severe acne often have a family history of acne. While there are many factors behind the inflammatory changes in acne, one of the most important is the different levels of bacteria found on the skin. While acne is not a bacterial infection, it's believed that inflammation results from the byproducts released by the bacterium found deep in the hair follicle. Generally CAD physicians treat acne with a topical prescription or oral medication, including antibiotics. Physicians also treat acne with Intense Pulse Light therapy to shrink the sebaceous glands associated with producing excess oils that contribute to acne.
