Ingredient review
Dimethicone Methacrylate
INCI: Dimethicone Methacrylate
A silicone polymer that helps products feel silky and last longer, but it's purely synthetic and not a treatment ingredient.
In plain English
Dimethicone Methacrylate is a man-made silicone ingredient that forms a thin, flexible film on your skin. It's often added to makeup and skincare to make them glide on smoothly, feel silky, and help the product stay put longer. Think of it like a lightweight, breathable shield that doesn't clog pores for most people.

Quick decision guide
Useful, but context matters
Dimethicone Methacrylate 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 Dimethicone Methacrylate.
- 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 derived from dimethicone (a common silicone) and methacrylic acid. It's designed to create a flexible, water-resistant film on the skin.
How it works
When applied, it dries down to form a thin, even film that helps other ingredients (like pigments or sunscreen actives) adhere better and last longer. It also gives a smooth, silky feel and can reduce the appearance of fine lines temporarily by filling them in.
Pros
Long-wear support
Helps makeup and sunscreen stay in place longer, reducing the need for touch-ups.
Smooth texture
Gives products a silky, non-greasy feel that glides on easily and blurs imperfections.
Cons and cautions
Synthetic only
Not naturally derived, which may be a drawback for those seeking plant-based or 'clean' formulations.
Potential pilling
If layered with incompatible products (e.g., water-based gels), it can ball up or pill on the skin.
Best for
- Anyone wanting long-wearing makeup or sunscreen
- People who enjoy a silky, smooth finish in their products
Use caution if
- Those who strictly avoid silicones or synthetic ingredients
- Individuals with very sensitive skin that reacts to film-forming agents
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. Low irritation and comedogenic potential. No major safety concerns reported in regulatory reviews.
Research notes
Limited independent studies on this specific ingredient. Safety is inferred from broader silicone polymer data. The Cosmetic Ingredient Review (CIR) has deemed similar silicones safe as used.
Common label clues
- Typical concentration
- Typically 0.5% to 5% in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Primers, Long-wear foundations, Sunscreens, Water-resistant products
- Environmental note
- As a silicone derivative, it may not biodegrade quickly. Some silicones have raised environmental concerns, though this specific polymer is less studied.
Good to know
- This ingredient is often found in 'transfer-proof' makeup
- It is considered non-comedogenic for most skin types
