Ingredient review
Methicone Crosspolymer
INCI: Methicone Crosspolymer
A gentle silicone powder that gives a silky feel and helps control shine without clogging pores.
In plain English
Methicone Crosspolymer is a silicone powder that feels silky and smooth on the skin. It helps absorb excess oil and gives products a soft, velvety finish. Because it's a crosspolymer, it forms a very light, breathable film that doesn't feel heavy or greasy. It's often used in primers and powders to blur pores and create a smooth base for makeup.

Quick decision guide
Useful, but context matters
Methicone 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 Methicone 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 that has been crosslinked to form a fine powder. It is chemically related to dimethicone but has a different structure that makes it more absorbent and less occlusive.
How it works
When applied, the powder particles sit on the skin's surface and absorb sebum (natural oil) and moisture, reducing shine. The crosslinked structure prevents the silicone from forming a heavy film, so the skin feels soft and matte rather than slippery or greasy.
Pros
Oil control without dryness
Methicone Crosspolymer absorbs excess oil on the skin's surface, helping to reduce shine throughout the day without stripping moisture or causing flakiness.
Smooth, blurring effect
Its fine powder texture fills in uneven areas and fine lines, creating a soft-focus effect that makes pores and texture less noticeable.
Cons and cautions
Can be hard to remove
Because it's a silicone powder, it may require a double cleanse or an oil-based cleanser to fully remove, especially if used in heavy layers.
Not biodegradable
As a synthetic silicone, it does not break down easily in the environment, which may be a concern for eco-conscious users.
Best for
- People with oily or combination skin who want a matte finish
- Anyone looking for a primer or powder that blurs pores and smooths skin texture
Use caution if
- Those who strictly avoid silicones in their skincare or makeup
Usage tips
Safety summary
Methicone Crosspolymer is considered safe for use in cosmetics. It has low irritation and comedogenic potential, making it suitable for most skin types. No significant safety concerns have been reported in scientific literature.
Research notes
Research on Methicone Crosspolymer is limited, but it is structurally similar to other silicone crosspolymers that have been evaluated for safety. The Cosmetic Ingredient Review (CIR) panel has reviewed related silicones and found them safe for use in cosmetics.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Primers, Foundations, Powders, Sunscreens
- Environmental note
- Methicone Crosspolymer is a synthetic silicone that is not biodegradable. However, its use in rinse-off products is limited, and it is generally considered low risk for aquatic environments at typical concentrations.
Good to know
- Methicone Crosspolymer is often listed alongside other silicones in ingredient lists, but it behaves more like a powder than a liquid silicone.
- It is considered non-comedogenic and safe for most skin types, including sensitive skin.
