Ingredient review
Methyl Methacrylate Crosspolymer-2
INCI: METHYL METHACRYLATE CROSSPOLYMER-2
A safe, synthetic powder that helps products feel silky and controls shine without clogging pores.
In plain English
Methyl Methacrylate Crosspolymer-2 is a man-made ingredient that looks like tiny, hollow plastic beads. In skincare and makeup, it acts like a sponge to soak up extra oil and gives products a smooth, silky feel. It's often used in powders and foundations to help them glide on easily and leave a matte finish. Think of it as a texture helper that makes your makeup feel lightweight and keeps shine in check.

Quick decision guide
Useful, but context matters
Methyl Methacrylate Crosspolymer-2 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 Methyl Methacrylate Crosspolymer-2.
- 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 crosslinked polymer made from methyl methacrylate monomers. It forms tiny, porous spheres that are added to cosmetic formulas to improve feel and absorb excess oil.
How it works
The microscopic beads create a physical barrier on the skin that absorbs sebum and moisture, reducing shine and helping makeup stay put. They also give a silky, velvety texture to products and can help other ingredients spread evenly.
Pros
Oil control
The porous beads soak up excess sebum, helping to keep your skin shine-free throughout the day without feeling heavy.
Silky texture
It gives products a luxurious, velvety feel that glides on smoothly, making application more pleasant and even.
Cons and cautions
Synthetic source
As a man-made polymer, it may not be suitable for those seeking all-natural or organic skincare routines.
Potential dryness
Because it absorbs oil, it can leave very dry skin feeling tight or flaky if used in high amounts.
Best for
- People with oily or combination skin who want a matte finish
- Anyone who prefers lightweight, non-greasy makeup and skincare
Use caution if
- Those with very dry or dehydrated skin may find it too absorbent and drying
