Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk

Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A crosslinked silicone polymer made from cetearyl dimethicone, meaning its molecules are linked together in a network. This structure gives it a soft, powder-like texture that feels velvety on skin.
How it works
When applied, it forms a flexible, water-resistant film on the skin's surface. This film helps other ingredients spread evenly, reduces the greasy feel of oils, and can improve the wear time of makeup or sunscreen by resisting sweat and humidity.
Pros
Silky, non-greasy feel
Creates a velvety texture that makes products feel lightweight and luxurious on skin, without the heavy or sticky sensation some emollients cause.
Improves product wear
Helps sunscreen and makeup resist water, sweat, and humidity, so they stay effective and look fresh longer throughout the day.
Cons and cautions
Requires double cleansing
Because it forms a water-resistant film, it may not rinse off with a gentle cleanser alone. You may need an oil-based cleanser or micellar water to fully remove it.
Not biodegradable
Like many silicones, this ingredient is not readily biodegradable in the environment, which may be a concern for eco-conscious users.
Best for
- Anyone who wants a smooth, non-greasy finish from their skincare or makeup
- People with oily or combination skin who dislike heavy textures
Use caution if
- Those who prefer silicone-free routines for personal or environmental reasons
