Dimethicone is a silicone-based substance commonly used in various skincare and cosmetic products, as well as in over-the-counter medications. It belongs to a class of compounds known as silicone oils.

Dimethicone works as an emollient, which means it helps to soften and moisturize the skin by forming a protective barrier on its surface. It is often found in skincare products such as moisturizers, lotions, and creams, where it helps to improve the skin’s hydration and smoothness.
