Is there synergy between UVB & UVA filters and Antioxidant Vitamins?
The inclusion of UVB filters and now the FDA approved Broad-spectrum UVA filter, Parsol 1789, into sun care and skin care products, can provide excellent protective shield for both cells and the immune system. Unfortunately, even products with high SPFs of 30 plus, can not completely block the entire spectrum of UV light. Some of the UV radiation which is not blocked penetrates deep into the skin, generating free radicals and negatively impacting on the cells. Recent studies have provided strong evidence that certain vitamins, such as vitamin E and C which are also antioxidants, can augment the performance of UV filters and thus provide the optimum Broad-spectrum protection against Environmental Stress and premature skin aging. Are there currently products in the U.S. market containing PARSOL 1789? The first product containing Parsol 1789 was introduced in 1993 by Schering-Plough under the trade name “Shade UVA Guard” (SPF 30). In 1997, Avon introduced “Age Block Daytime Defense Cream”
