(NewsUSA) - Acne's mortifying when you're a teen, but at least you can take comfort in knowing that, in a few years, you'll never again get a big zit before a big date. Or will you?

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

Adult acne, like teenage acne, is related to hormones. Teens get acne during puberty, and many adult women experience breakouts linked to their menstrual cycle.

But adult acne and teenage acne may require different treatments. Teenage acne typically affects the T-zone, while adult acne afflicts the jaw area.

Adult acne may be harder to treat. "Women have drier skin than teens. It is more sensitive and harder to treat (especially on the jaw), and some women may have difficulty tolerating the more drying over-the-counter topical acne treatments." explains Dr. Hilary Baldwin, associate professor and vice chairman of the Department of Dermatology at SUNY Downstate.

Women should talk with their dermatologists about prescription acne treatments, and be prepared for what may be an open-ended process. ACZONE (dapsone) Gel 5% has been FDA approved for the treatment of acne.

"The combination of moisturizing and anti-acne can be a tall order, so talking with a dermatologist can cut down on the treatment trial and error," adds Dr. Baldwin. "I also tell my adult acne patients to cleanse gently, moisturize when you need to and come and see me so we can find the right treatment."
