“The majority of acne I see in my practice in women in their 20s, 30s, and 40s is hormonal,” says Meera Sivendran, MD, assistant professor of dermatology at Mount Sinai in New York. These hormonal shifts, such as getting your period, getting pregnant, entering perimenopause, (the transition period before menopause when ovaries gradually make less estrogen), and then menopause increase oil production, says Eric Meinhardt, MD, founder and medical director of California Dermatology Specialists.
The three-piece set doesn’t come with a sun protection treatment, but Paula’s Choice has one in the line, the Clear Ultra-Light Daily Fluid SPF 30+. “Sun protection is really important, especially with acneic skin,” says Townsend. “In many cases, stronger acne products can make the skin photosensitive to the sun.” This isn’t your normal gloppy white sunscreen. Its fluid formula slips over tender skin, doesn’t need a ton of rubbing in, and also leaves a mattifying finish.
Acne products can be irritating, so many women find that a gentle drugstore face cleanser like this one from CeraVe keeps their skin in better balance. The foaming formula is more suitable for normal to oily skin types compared to creamier versions. Plus, it is formulated with hydrating ceramides and hyaluronic acid, so your skin won’t feel stripped at all.
Salicylic acid and azelaic acid. Azelaic acid is a naturally occurring acid found in whole-grain cereals and animal products. It has antibacterial properties. A 20 percent azelaic acid cream seems to be as effective as many conventional acne treatments when used twice a day for at least four weeks. It's even more effective when used in combination with erythromycin. Prescription azelaic acid (Azelex, Finacea) is an option during pregnancy and while breast-feeding. Side effects include skin discoloration and minor skin irritation.
