Sag-proof your skin

Start with the basics
Slather on SPF 30 every day and reapply throughout the day. Then use a topical antioxidant to quench harmful free radicals.

Mind the don'ts
"Smoking cuts off oxygen to the skin, wrecks collagen and elastin, and lowers your levels of estrogen, which are essential for keeping skin firm," says New York City dermatologist Joshua Zeichner, MD. If you consume alcohol, limit drinking to one or two drinks only once or twice a week, Dr. Zeichner adds. "Alcohol increases insulin levels, which creates low-grade inflammation and can hasten sagging."
