When it comes to skin care, most of us fall into one of two camps. There are those of us who never change our routine, using the same harsh face wash and lightweight moisturizer from our high school days. Then there's the other group, who embrace treatments like Botox and acid peels before there's even a wrinkle in sight.

Neither situation is ideal. But with a few simple updates, it's easy to find the happy medium. To help, we talked to New York dermatologist Heidi Waldorf, MD, and Olga Lorencin, esthetician and co-owner of Kinara Spa in Los Angeles. They gave us the scoop on what products are ideal for you in your 20s, 30s, 40s, and 50s. Follow their advice for your best possible complexion at every age.
