Moiturizers and sunscreens use Vitamin C, which protects the skin from UV damage and vitamin E, which repairs rough skin. But dermatological studies led by American specialist Dr. Sheldon Pinnell show that, when coupled with ferulic acid(a discovered by-product of plants), vitamins C and E become more stable and far more effective. The result: Skin gets double the protection from the sun-screens.

Chemists working for the U.S. Department of Agriculture (USDA) developed a biodegradable, non-toxic sunscreen called SoyScreen. SoyScreen could lead to a new class of cosmetic ingredients. It was developed by using an enzyme-based method to make an all-natural sunscreen from soy oil and ferulic acid, a natural antioxidant that filters out UVA and UVB sunlight. In February 2007, a variation of SoyScreen developed by Illinois-based iSoy Technologies started to be sold as a key active ingredient in a wrinkle-prevention skincare product. This soybean-based ingredient should soon appear in cleansers, haircare products, anti-aging and protective soaps.
