A Decade by Decade Guide to Healthy Skin, According to Top Derms

"Prevention is key at this age, so you must begin to topically apply products that contain antioxidants and collagen boosting ingredients and remember to wear an SPF every day," says dermatologist and founder of Dr. Dennis Gross Skincare, Dr. Dennis Gross.

Interestingly, modern technology actually poses some risks: "Double chins and sagging above the collarbone from constantly looking down at phones and computers are more visible in the younger demographic," says Dr. Paul Jarrod Frank, cosmetic dermatologist and founder of PFRANKMD & Skin. "Moreover, dehydration from alcohol and excessive amounts of sugar can affect the skin and cause wrinkles down the line, as well as smoking. If you cut these things out in your 20s and 30s, you will look significantly younger in your 40s and 50s."

In other words, it's a good time to start instituting good habits, as well as finding a skin care routine that works for you. "Start with the basics: a cleanser and lukewarm water to remove all traces of makeup and bacteria," advises dermatologist Dr. Michele Green. "If you're acne prone select a gel-based cleanser to get your skin nice and clean." She then recommends applying a toner to prepare the skin for the next step by opening the pores, allowing treatment products to be fully absorbed. "For sensitive skin select a toner with chamomile and green tea that is alcohol-free. If you're acne prone toners with alpha hydroxy, salicylic or glycolic acid are best." Lastly, she recommends a treatment product based on your particular need and a sunscreen (you can also use a treatment product formulated with a sunscreen to cut out one step).
