Ingredient review
Vinyl Dimethicone/Laureth Dimethicone Crosspolymer
INCI: VINYL DIMETHICONE/LAURYL DIMETHICONE CROSSPOLYMER
A silicone polymer that gives products a silky, smooth feel and helps ingredients spread evenly without clogging pores.
In plain English
This is a type of silicone that forms a very thin, breathable film on your skin. It's what makes many creams and primers feel silky and glide on smoothly. It doesn't absorb into the skin but sits on top, helping other ingredients spread evenly and giving a soft-focus effect. It's generally considered safe and non-irritating.

Quick decision guide
Useful, but context matters
Vinyl Dimethicone/Laureth Dimethicone Crosspolymer is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Vinyl Dimethicone/Laureth Dimethicone Crosspolymer.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 made by crosslinking vinyl dimethicone and lauryl dimethicone, creating a flexible network that improves product texture and stability.
How it works
It forms a flexible, breathable film on the skin's surface that smooths out fine lines and uneven texture. It also helps control the viscosity of a product, making it easier to apply and giving a non-greasy, velvety finish.
Pros
Silky texture
Creates a luxurious, velvety feel on the skin that makes products pleasant to apply and wear.
Non-comedogenic
Does not clog pores, making it suitable for acne-prone skin when used in appropriate formulations.
Cons and cautions
Silicone concerns
Some people prefer to avoid silicones due to environmental persistence or personal preference, though this type is not considered harmful.
Layering issues
If applied before water-based serums, it can create a barrier that reduces their absorption, so order of application matters.
Best for
- People who want a smooth, primer-like finish
- Those with oily or combination skin looking for a matte effect
Use caution if
- Individuals who avoid silicones for personal or environmental reasons
- Those with very dry skin who prefer richer, oil-based textures
Usage tips
Safety summary
Vinyl Dimethicone/Laureth Dimethicone Crosspolymer is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and no significant safety concerns have been identified in current research.
Research notes
Research on silicone crosspolymers focuses on their sensory and formulation benefits. They are well-tolerated in clinical patch tests and are not associated with skin sensitization. Long-term environmental impact is a topic of ongoing discussion, but human safety data is robust.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar silicone polymers and found them safe as used.
- Common uses
- Primers, Foundations, Moisturizers, Sunscreens, Serums
- Environmental note
- Silicones are generally not biodegradable, but this crosspolymer form is less likely to be released into waterways compared to volatile silicones. Some brands are moving toward biodegradable alternatives.
Good to know
- Silicone crosspolymers like this one are often used in 'blurring' primers and long-wear foundations.
- They are considered safe by major regulatory bodies and are widely used in cosmetics.
