CLEANSE Life in your 20s may equal late nights out, but it’s critical to wash your face before bed, no matter how tired you are. Riley suggests a gentle foaming formula like Benefit Foaming Cleanser ($21, sephora.com).
WEAR "Don’t rely on the SPF factor in your makeup,” says Riley, who suggests an SPF 30 for everyday use. "Those chemical sunscreens don’t have a lot of photostability." We like L'Occitane Angelica UV Shield SPF40 ($34, usa.loccitane.com), a lightweight fluid that absorbs almost instantly.
REPAIR The problems that plague 20-somethingsuneven skintone, the beginnings of fine lines and occasional breakoutsare all easy issues to address. We love Good Genes Treatment ($105, barneys.com), a cult favorite of Riley’s celebrity clientele. It prevents long-term collagen damage and blocks the causes of acne.Read MoreLess
