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

"By your 40s hormonal changes are apparent and your skin may not look as radiant as it did in your 20s and 30s," says Dr. Green. "It's time to add more hydrating lotions and potions to your skincare." She suggests swapping out your cleanser for a cleansing balm to hydrate your skin as it cleanses and making sure to use a toner that will replenish lost moisture, specifically ones made with aloe.

Exfoliation is also a key step at this age. "Your skin needs all the help it can get to stimulate cell turnover and this will help maintain a healthy complexion," says Dr. Green. You'll also want to step up your treatment product in terms of potency. "Your treatment products in this phase should be lightweight and able to penetrate deeper into your skin to repair and replenish," says Dr. Green. "Look for products containing antioxidants and peptides to stimulate collagen regeneration."
