has been awarded a patent for a skin smoothing composition that comprises sodium silicate, polyvalent silicate which is a hydrated magnesium aluminum silicate, and water carrier. The composition forms a film (with thickness of five microns to about 50 microns) when applied to an area of skin having wrinkles. It is comprised of sodium silicate, a polyvalent silicate which is a hydrated magnesium aluminum silicate, water; and a plasticizer. The ratio of the weight of the sodium silicate to the polyvalent silicate is approximately 1.0 to about 3.0 and the ratio of total silicate to plasticizer is equal to or less than 1.8. The composition is in the form of a gel or o/w emulsion and the pH is greater than 10.
