Skin care products can be expensive. Fortunately, it is possible to treat many of the conditions associated with rough, aging or acne-prone skin with vitamins. An additional benefit to adding these supplements to your diet is that boosting your intake of vitamins may have a long-term benefit for your heath. While a quality multivitamin may add adequate levels of each skin-clearing vitamin, you may prefer to supplement with each nutrient separately, so that you can control your intake.

Vitamin A

According to the Mayo Clinic, vitamin A is responsible for cellular growth. This is one reason why topical vitamin A, in the form of retinoid, is popular as a moisturizer. The enhanced cellular turnover leads to younger looking skin. Vitamin A is a fat-soluble vitamin considered safe to supplement.

Vitamins B5 and B6

Vitamins B5, also known as pantothenic acid, and B6, or pyridoxine, are part of the group of B vitamins known as B complex vitamins. These vitamins are vital for the development and maintenance of healthy eyes, skin and hair according to the University of Maryland Medical Center. Vitamins B5 and B6 are considered safe to supplement, however, the entire B range of vitamins work together, so it makes sense to choose a complete B complex supplement, to avoid changing the ratios of the different B vitamins in the body.

Vitamin C

Vitamin C is important in many functions of the body, including the development of collagen, a key component of skin. Vitamin C supplementation is generally safe, even in high doses; however, according to the National Institutes of Health, vitamin C can interact with a variety of medications. If you regularly take any prescription or over-the-counter medications, speak with your doctor before supplementing with vitamin C.

Vitamin E

Vitamin E is not only a vitamin, but also an antioxidant. It may reduce the damage of free radicals to certain systems of the body, including the skin. Like vitamin A, vitamin E is common in topical skin creams. According to the American Dietetic Association, vitamin E is one of the vitamins that Americans typically do not get enough of in their diet. They recommend 15mg a day of vitamin E, an amount not typically found in the average diet.
