Dimethicone/Vinyl Dimethicone Crosspolymer

Dimethicone/Vinyl Dimethicone Crosspolymer is a crosslinked silicone elastomer, often used as a fine white powder or gel in skincare and makeup. Think of it as a texture-improver: it helps formulas feel silky, soft, and more cushiony on the skin. It can also blur the look of pores and fine lines by creating a smooth, even surface, which is why it shows up in primers, foundations, sunscreens, moisturizers, and some hair products.

For skin, this ingredient is especially useful in products meant to feel lightweight but still elegant and refined. It can absorb some excess oil and sebum, so it’s often appreciated by people with combination or oily skin, or anyone who likes a more matte, powdery finish. In hair care, it can help reduce a rough feel and improve slip, making strands feel smoother and easier to manage.

Caveat: while it’s generally valued for comfort and texture, it doesn’t provide hydration or treatment benefits on its own. In very rich formulas, its smoothing effect may feel a bit too “silicone-y” for those who prefer a more natural finish. As with any ingredient, the overall formula matters more than the ingredient alone.
