Winter Skin Care

A. Vitamin A
It’s hard to find a derm who doesn’t love vitamin A in the form of topical retinol, one of the most effective weapons in the antiaging arsenal. When converted by the skin into retinoic acid, vitamin A boosts collagen production, stimulates cell turnover, and reduces the size and secretion of sebaceous glands, making it a potent cure-all for wrinkles, uneven skin tone, and acne. While stronger retinoic acids are available only by prescription, retinol—a milder form of vitamin A—is widely available over the counter.
B. Butter
Derived from the nut of the African karate tree, shea is one type of butter you can pile on guilt-free. It mimics skin’s own lipids, protecting it from irritation and speeding up its repair process.
C. Coffee
Talk about a wake-up call: Applied topically, vasoconstricting caffeine reduces redness and deflates undereye puffiness. Plus, the extract of the coffeeberry has 10 times the antioxidant power of other polyphenols such as green tea and pomegranate.
D. Vitamin D
Just a few minutes of sun exposure is enough to soak up a hefty dose of UVB rays, which help skin synthesize vitamin D, a proven deterrent to osteoporosis and heart disease. There’s no excuse for a bake-off, though—salmon and milk restock the nutrient without the risk of that other D: sun damage.
