“The inclusion of UVB filters and the FDA-approved broad-spectrum UVA filter, Parsol 1789, into sun care and skin care products, can provide an excellent protective shield. Unfortunately, even products with high SPFs of 30 plus, cannot completely block the entire spectrum of UV light,” says DSM.
“(Antioxidant vitamins )scavenge reactive oxygen species that are generated by exposure to UV radiation, and are deleterious to healthy cells,” says Gripp. “Antioxidant vitamins such as STAY-C 50 and vitamin E acetate have been shown to be effective in scavenging free radicals.”
She cited a study by Kerry Hanson, et al., in the Journal of the Society of Cosmetic Chemists, November/December 2003 that supports these findings.
Some UV filters, according to DSM, such as its Parsol MCX may be used in combination with UVA filters and other UVB filters for higher SPF values as well as for skin care, color cosmetics and everyday protection—or as a photostabilizer for cosmetic products.
These types of protection and treatment products allow marketers to include value-added options with the desired SPF to a variety of products.
