Benzoyl peroxide is an antibacterial ingredient, and it’s very effective at killing the P. acnes bacteria that causes breakouts. But benzoyl isn’t without its downsides. The leave-on creams and cleansing treatments can dry out sensitive skin types and bleach clothing if you aren’t careful. Board-certified dermatologist Eric Meinhardt, M.D., previously told SELF that it's best to stick to formulations that have no more than 2 percent of benzoyl peroxide listed on the active ingredients chart; stronger concentrations are harder on your skin without being any tougher on bacteria.
For years the French have have opted for super moisturizing cold creams. You simply massage this in and then wipe off with a tissue or a warm washcloth and you're left with super soft skin. It removes makeup without leaving skin feeling "tight." Plus, because you aren't using water to rinse the face, you might be saving your skin from the drying effects of water.
That’s why, no matter how uncomfortable your skin may feel while plagued with acne, you must resist the urge to touch your skin. If the irritating sensations become unbearable, there are other methods of treating your skin, such as cooling it with ice packs or aloe vera gel. You can even use medicated creams designed to soothe irritated skin – given that your dermatologist says it’s okay.
Your pimples need TLC, too. The study on acne vulgaris found that, in an attempt to dry out acne lesions, patients often use too many products or apply excessive amounts to problem areas, resulting in further irritation and over drying of the skin. Vigorous scrubbing and using harsh exfoliants can make acne worse by rupturing whiteheads and blackheads, turning them into painful red ones. And remember: no matter how satisfying it is, picking and popping your zits will also increase inflammation and opportunity for infection.
You’d be hard-pressed to find a derm who won’t tell you to run to the drugstore to pick up this retinoid, the only one available OTC. A retinoid (a vitamin A derivative that speeds cell turnover) can treat acne by exfoliating the skin to prevent clogged pores, says Dr. Meinhardt, who recommends Differin to patients. Use a few times per week and then build up to nightly use, he says. (Once you’ve got control of your acne, check out these OTC retinol products for a complete skin overhaul. They’ll ban blemishes, reduce wrinkles, and combat aging.)
Genetics play a big part in who gets acne and how severely, but each blemish can be blamed on some combination of sebum production, a bacteria called Propionibacterium acnes (P. acnes), plugged follicles, and inflammation. Finding a good treatment is really about finding the right combination of ingredients to troubleshoot each of those issues. Some factors that might worsen acne include hormones, certain medications, diet and stress.
Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin). Topical antibiotics alone aren't recommended.
