Apply a liquid skin care product that contains 3 to 10 percent vitamin C onto your face in the morning after exfoliating, instructs The Dr. Oz Show. If the vitamin C causes dry skin, apply a moisturizer after using it. It is best to use vitamin C in the morning because it blocks some of the damaging effects of the sun.
It's safe to pair products that contain vitamin C with any other skin care products, according to The Dr. Oz Show. If you want to combat the signs of aging, try combining products that contain vitamin C with vitamin E skin care products. When purchasing vitamin C skin care products, look for products in opaque, airtight containers, which protect the vitamin C from degradation due to exposure to light and air.
Vitamin C is an antioxidant that can help increase the collagen production in the skin and fight wrinkles, states The Dr. Oz Show. It can also treat sun damage and reverse visible signs of damage, such as sun spots and fine lines.
Be prepared to wait at least six to eight weeks to see any results from adding vitamin C to your skin care regimen, notes The Dr. Oz Show. The maximum benefit of this antioxidant is usually apparent after approximately six months of continuous use.
