Ingredient review
Dimethicone/Vinyl Dimethicone Crosspolymer
INCI: Dimethicone/Vinyl Dimethicone Crosspolymer
A silicone powder that blurs pores and controls shine without feeling heavy or greasy.
In plain English
This is a silicone-based ingredient that forms a soft, powdery film on the skin. It feels silky and smooth, helps absorb excess oil, and can make makeup last longer. Because it's a crosspolymer (a network of silicone chains), it doesn't sink into pores or feel sticky. It's often used in primers and powders to give a matte, blurred finish.

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 that has been crosslinked to create a three-dimensional network. In cosmetics, it appears as a fine powder or a gel-like substance that provides a velvety texture.
How it works
When applied, it spreads into a thin, breathable film that sits on the skin's surface. This film absorbs sebum and sweat, reduces the appearance of pores and fine lines, and helps other ingredients (like pigments) stay in place. It does not penetrate the skin.
Pros
Silky, non-greasy feel
Leaves skin feeling velvety smooth without any sticky or oily residue, making it ideal for primers and powders.
Shine control
Absorbs excess sebum and sweat, helping to keep skin looking matte and fresh throughout the day.
Cons and cautions
Can be drying for some
Because it absorbs oil, people with naturally dry or dehydrated skin may find it makes their skin feel tight or flaky.
Requires thorough removal
Silicone crosspolymers can cling to the skin and may not rinse off with a gentle cleanser alone; double cleansing is often needed.
Best for
- People with oily or combination skin who want a matte finish
- Anyone looking for a primer or powder that blurs pores and smooths texture
Use caution if
- Those with very dry or dehydrated skin may find it too mattifying or drying
