Dimethicone Skin Benefits:
Astringent
Moisturizing
Soothing

Dimethicone is a man-made, silicone molecule that possesses excellent emollient properties. Topical application of dimethicone can form a protective barrier that can help to improve moisture-retention, thus increasing skin-hydration. Dimethicone skin benefits may also include skin-soothing and astringent properties. 1 Furthermore, due to its large chemical structure, certain forms of dimethicone, such as dimethicone PEG or PPG, are used as emulsifiers to provide skincare products with a uniformly smooth, silky texture. When paired with certain slip agents, dimethicone (PEG or PPG) can serve as a viable solution stabilizer.  For this reason, cosmetic formulas frequently infuse dimethicone for skin spreadability purposes. 2
