If there are multiple ice pick scars, acne scar treatment devices that use radiofrequency energy are Dr. Hellman’s first choice. “These treatments help build collagen from the inside out, and collagen helps to fill the scars from within,” she says. Several treatments are usually needed. The procedures are done using local anesthesia, and it’s effective in all skin types, she says. In one study, published in a 2015 issue of the Journal of Cosmetics, Dermatological Sciences and Applications, Dr. Hellman found that approximately four treatments with a radiofrequency device produced significant improvement in the depth of the scars. A follow-up study in a 2016 issue of the same journal showed that these results held for up to two years, although some people had touch-ups.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
