Concern level

High concern

A silicone polymer used in cosmetics as an emollient, skin protectant, slip agent, and texture modifier. The term "100% medical-grade silicone" is not a standard INCI name; in skincare it most often corresponds to dimethicone or related polydimethylsiloxane silicone materials. It forms a breathable, water-repellent film that helps reduce transepidermal water loss and improve product spreadability and skin feel.

Interactions

incompatible with: No clinically important direct ingredient interactions are established for topical dimethicone. In very occlusive formulas, it may alter the feel or spread of highly water-based actives rather than chemically inactivating them.

Risks & Warnings

Generally very low irritation potential. Main concerns are product-specific rather than the silicone itself: possible occlusion in very heavy formulas, and rare sensitivity to additives or impurities in a blended silicone product. Injectable silicone is not the same as topical cosmetic silicone and carries different medical risks.
