Silicone Film Former Blend
INCI: Vinyldimethyl/Trimethylsiloxysilicate Stearyl Dimethicone Crosspolymer
A silicone polymer that helps makeup last longer and feel smooth, but may not suit those avoiding silicones.
In plain English
This is a silicone-based ingredient that forms a thin, flexible film on the skin. It helps makeup stay in place longer, resists water and sweat, and gives a silky, non-greasy feel. Think of it like a clear, breathable shield that helps your foundation or sunscreen stay put without feeling heavy.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic silicone polymer created by crosslinking silicone chains. It is a solid or waxy powder that is often dispersed in oils or silicones for use in formulas.
How it works
When applied, it spreads into a uniform, flexible film that adheres to the skin. This film helps lock in pigments and active ingredients, reduces transfer to clothes or masks, and provides a smooth, velvety finish. It also improves water resistance in sunscreens and long-wear products.
Pros
Long-wear performance
Helps foundation and concealer stay put for hours without fading or transferring to masks or clothes.
Smooth, silky feel
Creates a velvety, non-greasy texture that makes skin feel soft and primed for makeup.
Cons and cautions
Synthetic origin
Made from petrochemicals, which may not align with natural or eco-conscious beauty preferences.
Potential for buildup
Can feel heavy or occlusive on very oily or acne-prone skin, potentially contributing to clogged pores in some individuals.
Best for
- People who want long-wearing makeup or water-resistant sunscreen
- Those with normal to dry skin who enjoy a smooth, velvety finish
Use caution if
- Those strictly avoiding all silicones
- Very oily or acne-prone skin types if they find silicones clogging
Usage tips
Safety summary
Generally considered safe for topical use in cosmetics. Low irritation and comedogenic risk. However, as a synthetic silicone, it may not be suitable for those with very sensitive or acne-prone skin, and its environmental persistence is a concern.
Research notes
Limited peer-reviewed studies specifically on this polymer, but silicones as a class have a long history of safe use in cosmetics. The Cosmetic Ingredient Review (CIR) panel has reviewed similar silicone polymers and found them safe as used.
Common label clues
