From your early 20s (think prevention and protection) and into your 40s (think repair and replenish), your skin care needs will change. We’ve done the research and have you covered with these great, hardworking skin care products.

Throughout each decade of life, our skin asks something different of us. Putting forth extra effort for the care of our skin is important, whether we're in our 20s, when our biggest concern is prevention of future skin troubles; in our 30s, when we're starting to see signs of aging; or in our 40s, when we're working diligently to keep our skin as healthy and youthful as possible.

Here's our decade-by-decade guide to caring for your skin, and some product recommendations to help slow the signs of aging and keep your skin healthy and glowing.

In your 20s

Dr. Michel McDonald, assistant professor of medicine (dermatology) at Vanderbilt University Medical Center, stresses that the best thing that women in their 20s can do for their skin is to establish a great skin care regime early on and follow it faithfully. A great cleanser, a skin-appropriate moisturizer and sunscreen with SPF 15 or higher (in your moisturizer or as a separate product), are all you really need in your 20s.

In your 30s

By the time we're in our 30s, fine lines and wrinkles begin to appear, and it's time to add a few products to the great skin care regime we established in our 20s. Incorporating an antioxidant-rich moisturizer to help combat free radicals, a daily eye cream and a night cream with retinol will help keep our skin looking as healthy as can be.

In your 40s

Once we're in our 40s, we begin to see cumulative sun damage in the form of blotchiness, red spots and ruddiness. Lines and wrinkles also begin to deepen with each passing year as we lose collagen and moisture. This is when it's a great idea to add a retinoid to our routine a few times a week, which will help reduce fine lines and wrinkles, smooth rough patches and address hyper-pigmentation. But with these improvements comes drier skin, so adding moisture back in is a must. Face oils are a great way to restore lost moisture and impart a glow to your skin.

Products we love: Philosophy Miracle Worker Miraculous Anti-aging Pads and Solution, and Calme Face Oil Concentre.

Taking age-appropriate care of your skin for a few minutes each day will help keep you looking good for decades to come.
