Blemishes aren't just for One Direction fans. Stress, a poor diet, and hormones can wreak havoc on an adult complexion.
The RX: You may be tempted to pile on the zit zappers. Don't. "Your skin isn't as oily as it was during your teenage years," says Nicholas Perricone, M.D., author of The Acne Prescription. "Drying products can just cause more problems." Swap salicylic-acid cleansers for gentle options like Cetaphil or CeraVe, and ask your derm to write you a prescription for Retin-A to decrease and prevent blemishes. (A pea-size amount coats your entire face.) Finish with a light gel moisturizer—yes, we said moisturizer. (Dry skin can trigger more pore-clogging oil.) Stubborn blemishes around the mouth may signal a hormonal imbalance and require oral antibiotics such as doxycycline or spironolactone.
Lifestyle Fixes: Two weeks before the big day, cut coffee, dairy, sugar, booze, and processed foods, and switch to a diet of salmon, organic lean meat, whole grains, fruit, veggies, and green tea. Top it off with 30 minutes of exercise per day, which helps cut stress. "What you eat makes all the difference," says Perricone. "An anti-inflammatory diet clears acne and decreases fine lines, pores, and puffiness so you ll look your best."
