What it is

A crosslinked polymer made from lauryl methacrylate and glycol dimethacrylate, creating a network of tiny beads that absorb oil and provide a smooth, matte finish.

How it works

When applied to skin, the crosspolymer forms a thin, flexible film that helps other ingredients adhere evenly. It also absorbs excess sebum, reducing shine and giving a soft-focus effect that blurs pores and fine lines.

Pros

Silky texture

Creates a smooth, velvety feel on skin that makes makeup and sunscreen more pleasant to apply.

Oil control

Absorbs excess sebum, helping to reduce shine and keep makeup looking fresh longer.

Cons and cautions

Synthetic origin

Made from petrochemicals, which may not align with clean-beauty or eco-conscious preferences.

Limited long-term data

While generally considered safe, there is less independent research on this specific polymer compared to more common ingredients.

Best for

  • People with oily or combination skin looking for a matte finish
  • Anyone who wants a lightweight, non-greasy foundation or sunscreen

Use caution if

  • Those who prefer 100% natural or plant-based ingredients
  • Individuals with known allergies to acrylates (rare)

Usage tips

Look for this ingredient in primers and mattifying moisturizers for best oil-control results.
Shake products containing this polymer well before use to ensure even distribution.
