Drink plenty of water, don't smoke, and wash your face and body each day with a gentle hypoallergenic soap for healthy-looking skin, says Dr. Dawn Davis, a Mayo Clinic dermatologist.

And, after bathing, moisturize with a hypoallergenic, fragrance-free moisturizer when you're done to help the skin hydrate.

With so many products from which to choose, how do you pick the right moisturizer? Dr. Davis says hypoallergenic is the key.

"Unscented doesn't necessarily mean that it doesn't have fragrance. Oftentimes unscented just means more chemicals," says Dr. Davis.

What ingredient should you look for?

The most inert natural hypoallergenic product that you can find in a moisturizer is petrolatum as in petroleum jelly.

Dr. Davis has another important tip for healthy skin care that could potentially save your life: "Please remember to wear your sunscreen."
