If you have oily/breakout-prone skin, we'll start with the good news: The excessive oil production of your earlier years might have stabilized, leaving you with just a few breakouts around the time of your period. The bad news, though, is that deep cysts, usually along your mouth, chin, jawline, and neck, show up more frequently. Hormonal fluctuations and stress can sometimes result in severe acne, in which case you should consult a dermatologist for a more targeted regimen.
What helps: Try Vichy Reti-C Intensive Corrective Care SPF 15 a moisturizer with retinol and vitamin C. And Jeanine B. Downie, MD, a Montclair, New Jersey-based dermatologist, often prescribes Differin, a retinoid that helps normalize pores.
What hurts: Don't touch your face with your hands. And stress raises levels of cortisol, the hormone that triggers excess oil production -- so relax!
