Description: Dimethicone is an excellent skin care product but whether it is right for you depends on what you are looking for. It is a type of silicone oil. Silicone Oils in general add glide and smooth properties to skin care products. Dimethicones are unmodified silicone oils. Unmodified silicone oils stay on the surface of the skin as the molecules are too large to penetrate deeply into the skin. Because it stays on the surface of the skin, dimethicone provides a skin barrier.
Dimethicone is just one of the polymers derived from its mother element, silicon or silica. Silicon dioxide occurs naturally and scientists have made great breakthroughs in combining silica with other natural elements like carbon, oxygen and hydrogen to form a polymer.
