Of all the news coming from the beauty community, the loudest buzz may be about the power of vitamins, minerals, and other nutrients to give skin a more radiant, healthy, and, yes, youthful glow.
The excitement is focused not only on creams and lotions you put on your skin but what you put into your body as well. Health experts say that vitamins and minerals in all forms play an integral role in a healthy complexion, whether the source is food, supplements, or even a jar of cream.
"Your skin is the fingerprint of what is going on inside your body, and all skin conditions, from psoriasis to acne to aging, are the manifestations of your body's internal needs, including its nutritional needs," says Georgiana Donadio, PhD, DC, MSc, founder and director of the National Institute of Whole Health in Boston.
"There is a lot of important new research showing tremendous power of antioxidants in general, and in some specific nutrients in particular that can make an important difference in the way your skin looks and feels -- and even in how well it ages," says nutritional supplement expert Mary Sullivan, RN, co-founder of Olympian Labs.
So which nutrients do you need to keep your skin healthy and looking its best? According to the experts interviewed by WebMD, plus new information from the American Academy of Dermatology (AAD), the following vitamins, minerals, antioxidants, and other nutrients nourish your skin, whether you take them in supplement form, apply them directly to your skin, or make sure you get enough from the foods you eat.
Studies show that the vitamins C, E, A, K, and B complex all help improve skin health and appearance. Here's how.
Vitamin C. Among the most important new dermatological discoveries is the power of vitamin C to counter the effects of sun exposure. It works by reducing the damage caused by free radicals, a harmful byproduct of sunlight, smoke, and pollution. Free radicals gobble up collagen and elastin, the fibers that support skin structure, causing wrinkles and other signs of aging. Make sure your diet includes plenty of vitamin-C rich foods (citrus and vegetables, among others), which can replace the loss of the vitamin through the skin. You can also take vitamin C supplements, up to 500 to 1,000 milligrams of per day, according to the AAD. Combined with vitamin E (see below), vitamin C supplements can also protect skin from sun exposure.
You can also try a topical vitamin C cream to encourage collagen production, just as your body does naturally when you are young. The trick here is to use a formulation containing the L-ascorbic acid form of vitamin C, the only one that can penetrate skin layers and do the job.
Vitamin E. Research shows that, like vitamin C, this potent antioxidant helps reduce the harmful effects of the sun on the skin. According to studies published by the AAD, taking 400 units of vitamin E daily appeared to reduce the risk of sun damage to cells as well as reduce the production of cancer-causing cells. Some studies show that when vitamins E and A are taken together, people show a 70% reduction in basal cell carcinoma, a common form of skin cancer. Vitamin E can also help reduce wrinkles and make your skin look and feel smoother. (Be aware, though, that some recent research warns that large doses of vitamin E can be harmful. Stay with 400 international units per day or less to be on the safe side.) Used in a cream, lotion, or serum form, vitamin E can soothe dry, rough skin. When combined with vitamin C in a lotion, it's highly protective against sun damage, says the AAD.
Vitamin A. If your vitamin A levels are up to snuff from the foods you eat, adding more probably won't do much more for your skin. That said, if those levels drop even a little below normal, you're likely to see some skin-related symptoms, including a dry, flaky complexion. That's because vitamin A is necessary for the maintenance and repair of skin tissue. Without it, you'll notice the difference. Fruits and vegetables are loaded with vitamin A.
Topical vitamin A is the form that makes a real difference in your skin. Medical studies show a reduction in lines and wrinkles, good acne control, and some psoriasis relief, all from using creams containing this nutrient. The prescription treatment is called Retin A, and it's used primarily as a treatment for acne. The less potent, over-the-counter formulations are sold as retinols and used as anti-aging treatments.
Vitamin B Complex. When it comes to skin, the single most important B vitamin is biotin, a nutrient that forms the basis of skin, nail, and hair cells. Without adequate amounts, you may end up with dermatitis (an itchy, scaly skin reaction) or sometimes even hair loss. Even a mild deficiency causes symptoms. Your body makes plenty of biotin, and the nutrient is also in many foods, including bananas, eggs, oatmeal, and rice.
Creams containing B vitamins can give skin an almost instant healthy glow while hydrating cells and increasing overall tone at the same time. Niacin, a specific B vitamin, helps skin retain moisture, so your complexion looks more plump and younger looking in as little as six days. It also has anti-inflammatory properties to soothe dry, irritated skin. In higher concentrations it can work as a lightening agent to even out blotchy skin tone.
DMAE. Another powerful antioxidant, this nutrient has one of the strongest appetites for free radicals. It works mostly by deactivating their power to harm skin cells. It also helps stabilize the membrane around the outside of each cell so that assaults from sun damage and cigarette smoke are reduced.
Essential Fatty Acids (EFAs). If your skin is dry, prone to inflammation, and frequently dotted with white heads and black heads, you may be lacking essential fatty acids, nutrients that are crucial to the production of skin's natural oil barrier. Without an adequate supply of EFAs, the skin produces a more irritating form of sebum, or oil, which can result in problems.
The solution, say skin experts, may be to balance two of the key EFAs, omega-3 and omega-6. While most folks get plenty of omega-6s (in baked goods, cooking oils, poultry, grains, and many other foods), omega-3s are often lacking. They're found mostly in cold-water fish, including salmon, sardines, and mackerel, flaxseed, and flax and safflower oils. Taking supplements, such as fish oil capsules or evening primrose oil, may also help keep your skin smoother and younger-looking.

Avocado oil is relatively thick and rich oil that may be diluted with other carrier oils to work its consistency.

It is bright and golden in color and is regarded as the most favored in the carrier oil family because of its advanced molecular stability. Also makes a great scalp cleanser for the hair, and is equally wonderful for the skin because it has absorption properties that are similar to our skins own sebum.
Rosehip seed oil. Rosehip seed oil contains Vitamin A, which helps to delay the effects of skin aging, assists with cell regeneration, and promotes collagen and elastin levels to increase. This results in firmer, smoother, and more youthful skin with greater elasticity. Rosehip seed oil also contains a high amount of essential fatty acids and Vitamin E, which further promotes healthy skin. In particular, it is rich in linoleic and linolenic acids, which are important, skin nutrients. Rosehip seed oil has been used successfully to treat the following skin problems: Stretch marks UV damage from overexposure to the sun Scars from surgery, burns, and acne Eczema Psoriasis Wrinkles and premature skin aging Hyper-pigmentation Dermatitis Burns, including hose from radiation and sunburns Age spots Brittle nails Dry and damaged hair.
