Dimethicone and Silicones
Dimethicone and Silicones — a family of synthetic polymers used in skincare to improve texture, spreadability, and skin feel while forming a breathable, flexible film on the surface. Dimethicone is one of the most common silicones, valued for smoothing skin, softening the appearance of fine lines and pores, and helping reduce moisture loss.
Key points
- Silicones like dimethicone create a smooth, silky slip that improves how products glide and feel on the skin.
- They form a lightweight, semi-occlusive film that can help reduce water loss without a heavy or greasy feel.
- Dimethicone is widely regarded as non-comedogenic and non-irritating, and is used in primers, moisturizers, and barrier products.
- Silicones are cosmetically inert and do not 'suffocate' skin, though preferences vary and some users choose silicone-free formulas.
