Polymethylsilsesquioxane is a silicone ingredient that can be used in many skin care, hair care and cosmetic formulations. It is most commonly used as a film-forming agent to create a silky feel and increase the waterproof ability of skin and hair. It is a “spherical, fine-grained silicone resin” made up of many tiny particles that can be easily evenly distributed in the formula. In a study conducted by cosmetics developer Grant, polymethylsilsesquioxane particles can be no more than 10 microns, giving hair skin anti-caking and slippery properties in addition to lubricity and waterproofing.
The cosmetics database considers polymethylsilsesquioxane as a 100% safe ingredient.
Although a large number of studies have linked silicone to cancer and organ failure, it is generally believed that silicone is a harmful ingredient only when injected into the skin and body, and topical application is harmless. There are also many studies that suggest that silicone (including polymethylsilsesquioxane) is safe for humans, including a study published in the English Medical Journal that studied more than 1000 women with breast implants for more than 14 years. A team of researchers and doctors concluded that “according to the different definitions, signals and symptoms of these diseases” We found no association between silicone breast implants and connective tissue diseases.
According to a Marta post about silicone, it is believed that silicone residue or attachment to the surface of the skin will not cause allergic reactions. Silicone molecules (such as polymethylsilsesquioxane) are too large to penetrate the skin and cell membrane.
So Polydimethylsiloxane is generally harmless to the skin. Polydimethylsiloxane is generally used in skin care products to moisturize the skin, but also can play a lubricating and moisturizing effect, generally will not cause irritation to the skin, and will not cause harm to the skin. It is still recommended to use regular brand skin care products. If you buy inferior skin care products, it may lead to excessive addition, thus causing irritation to the skin。
