Although acne traditionally has been considered a disease of teenagers, it is also extremely common in adult women. Studies show that acne affects more than 50 percent of women between the ages of 20-29 and more than 25 percent of women between the ages of 40-49 (1). In fact, after age 20, women are far more likely to report having acne than men. While there is no cure for acne, dermatologists are finding that hormonal therapies can help some women fight bothersome acne that occurs in adulthood.
