Vitamin C plays an important role in internal bodily functions, but it also has additional benefits for the skin. When choosing a vitamin Cmoisturizer, consider your skin type and what results you're looking for from your moisturizer.
Vitamin C is a powerful antioxidant that may help reverse the signs of aging, protect against ultraviolet rays, and lessen the effects of prolonged sun exposure.
Moisturizers containing vitamin C are often good for people with mature skin. The vitamin plays a vital role in the formation of collagen, a structural protein that provides structure to the face by connecting soft tissues with the skeleton. As people age, the production of collagen slows down, resulting in fine lines and wrinkles on the skin. Skin with an insufficient amount of collagen also bruises easily.
When choosing a vitamin C moisturizer, look for "L-ascorbic acid" on the label. L-ascorbic acid is the water soluble form of vitamin C. You might also look for one that contains hyaluronic acid, which increases the formula's penetration into the skin. Hyaluronic acid is especially beneficial for mature or dry skin, as it helps lubricate.
Ascorbyl palmitate, also used in skin care, is a fat-soluble derivative of vitamin C. It is more stable than pure vitamin C, and is less likely to irritate the skin. If you have sensitive skin, ascorbyl palmitate may be a better choice.
If you have mature or dry skin, look for a vitamin C moisturizer in the form of a rich cream with essential fatty acids. Most people with mature skin also have dry skin. Ingredients like grapeseed oil and avocado oil moisturize and nourish the skin. By moisturizing the skin and promoting collagen synthesis, these vitamin C moisturizers will brighten and improve the skin's appearance.
If you have oily or combination skin, choose a light vitamin C moisturizer with an oil-free formula. People with oily or combination skin should use the moisturizer to balance sebum production while improving elasticity and brightening skin. Some products with vitamin C may help acneor burn scars fade.
There is a downside to moisturizers containing vitamin C. The molecules in this vitamin are quite unstable; once the vitamin C moisturizer is exposed to an excessive amount of oxygen, it will not be as effective and may actually increase the formation of free radicals. If you purchase a vitamin C moisturizer, check to make sure that the product is in an air-tight sealed package. If you suspect that your vitamin C moisturizer has oxidized, stop using it.
