If you look at the ingredient list of your shampoo, conditioner, moisturizer or sunscreen, you are likely to come across "polydimethylsiloxane" or "Dimethicone". This is precisely the "manifestation" of dimethicone in the field of personal care. It has become one of the most widely used ingredients in modern cosmetics, thanks to its ability to bring unique texture and excellent performance to the products. 
Among hair care products, dimethylsilicone oil plays a particularly significant role. It has excellent spreading and adsorption properties, and can form a thin and breathable protective film on the surface of the hair. This film can effectively smooth the hair cuticles, significantly reduce the friction between the hairs, thereby providing an instant feeling of smoothness and shine, and preventing damage caused by combing. It makes the "combing through to the end" experience possible. 
In skincare products and makeup, it also plays a significant role. It can give the cream a smooth and silky texture, making it easy to apply. It forms a breathable film on the skin, which can lock in moisture without causing a greasy or heavy feeling, providing a refreshing "silky" sensation. In sunscreen products, it helps to form a film, enhancing the waterproof and sweat-resistant properties of the formula. 
Although there were once disputes about its "clogging pores" effect, numerous studies and long-term practices have shown that cosmetic-grade high-purity dimethylsilicone oil is stable, inert, and has extremely low allergenicity. It is a safe and effective ingredient. Through technological means, it transforms the excellent properties of industrial materials into the magic power to enhance the personal care experience.
