50 Best Skin-Care Tips of All Time
Master your Retinoids
Vitamin A derivatives are key to anti-aging regimens, yet many women avoid them because they're irritating. Dr. Day recommends building up tolerance by using a pea-size drop every other day. Or for a milder version, try Atralin ($192; by prescription). "It's a gel base and gentler than thicker creams," says San Francisco dermatologist Seth Matarasso. Whichever retinol you opt for, counter redness with an antioxidant-rich moisturizer like Revaléskin night cream with coffeeberry ($72; skinstore.com).
