Pregnancy hormones can make your skin go bonkers! But with a long list of ingredients to avoid until your due date, what are you supposed to do if you get a pimple (or a whole bunch of ’em)? Follow this easy plan for clear skin from Ariel Ostad, M.D., a dermatologist in New York City.

High levels of estrogen increase sebum production. Wash your face with a cleanser containing rosemary extract or tea tree oil, which keep breakouts at bay by killing bacteria. Stay away from well-known acne-fighters, like benzoyl peroxide, retinol and salicylic acid—they’re not safe for pregnant women, even if they come from a natural source.

Complexion-clearing ingredients can dry and irritate skin; sidestep the re-hydrators and your oil glands will kick into overdrive to compensate. An oil-free lotion or cream with glycerin, shea butter, hyaluronic acid or niacinamide (vitamin B3) softens without clogging your pores or giving you blemishes. Apply it on clean skin before bed.

If you’ve been picking, you might see residual dark spots. To fade or prevent acne scars, apply a serum with antioxidant vitamin C on bare skin every morning. Choose a product in an airtight bottle with a pump— vitamin C could lose its potency if exposed to air and light.
