For oily skin, a mild toner or astringent may be helpful. According to Dr. Amiya Prasad, a cosmetic surgeon in New York who also spoke to ABCNews, "There is some role in using toners to help even out the areas that are oily and to make your skin look more uniform."

Visit the skin care department in your local grocery store or pharmacy and you’re sure to see a wall of creams, ointments, gels and sprays for a variety of skin conditions. Don’t think that you have to stock up on a cream for every situation - a general moisturizer or toner is enough to keep up a basic, healthy skin regimen. If you do have specific skin concerns, talk to a dermatologist before shelling out for unnecessary products. Also, pay attention to natural ways to make sure your skin (and body) are hydrated like making sure you’re drinking enough water every day.

Clear Skin Starts from the Inside

Besides the requisite 8 glasses of water a day, or more, you can nourish your skin from the inside with the right foods and vitamins.

Add these to your grocery list so you can feed your skin what it needs to glow:

• cocoa - hydrates skin, making it firmer and more supple;
• yogurt - firms skin which in turn helps prevent lines from developing;
• pomegranates - regulate skin’s blood flow to keep your cheeks rosy pink;
• walnuts - essential fatty acids in these and other nuts help your skin keep its elasticity and avoid that “crepe-y” look that happens as we age; and
• yellow and orange peppers - contain carotenoids that help block out the sun.
