You cannot just start one regimen and then decide to stop after. Consistency is also needed in order to see great results. This especially true with skin care that aims to prevent the onset of aging. This involves blind faith as you will not be able to see the results of your efforts until after several years when you grow old and everybody around you have wrinkles and you do not. Based on long-term reduction of wrinkles, instant reducing of fine lines, antioxidant protective properties that delay skin cell aging, collagen and skin renewal properties and skin smoothing properties, the most common skin care creams include Rejuvinol, Alpha Derma, Idebenol, Strixderm, Avotone, Strivectin-SD, Rejuvenex, and Hydroderm. Skin care experts still recommend the use of sunscreen for maximum sun protection. Still, vitamin C can be combined with sunscreens for more coverage and longer protection because once this gets into the skin, it cannot be easily washed or rubbed off. Vitamin C as an anti-oxidant Vitamin C is known to play a crucial role in the oxidation process. One way to do this is by using safe and effective sun protection. Studies show that 90 percent of facial aging is cause by the damage brought by UV rays and radiation. You can protect yourself from UV rays by applying sun block or sunscreen daily, wearing clothing that helps protect your skin from the sun's rays such as long sleeves and pants along with wide brimmed hats, and by lessening your exposure to the sun especially in its peak hours-10a. Experts say that aging caused by overexposure to the sun's ultra violet rays is called "photo-aging." In this process, the sun's rays breaks down the collagen and elastin in the person's skin that lead to the development of premature wrinkles and other facial lines. You can protect yourself from the harmful rays of the sun by applying sun blocks and sun screens that has high SPF content. Also look for sunscreen that blocks both UVA and UVB rays, especially those labeled with "broad spectrum protection" or UVA protection for formulation with an SPF of 15 or greater. Select a sunscreen that is labeled "nonacnegenic" or "noncomedogenic" to help keep pores clear and also prevents the skin from having pimples or acne.
