Ingredient review
Phosphorylcholine Glycol Methacrylate Crosspolymer
INCI: PHOSPHORYLCHOLINE GLYCOL METHACRYLATE/PEG-10 DIMETHACRYLATE CROSSPOLYMER
A gentle, biomimetic film-former that helps lock in moisture and improve skin feel without clogging pores.
In plain English
This ingredient is a synthetic polymer that creates a thin, flexible film on your skin. It's designed to mimic the structure of natural cell membranes, so it feels very compatible with your skin. The film helps reduce water loss (keeping your skin hydrated) and gives a smooth, silky finish. Because it's large and doesn't penetrate deeply, it sits on the surface and is unlikely to cause irritation or breakouts.

Quick decision guide
Easy yes for most routines
Phosphorylcholine Glycol Methacrylate 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 Phosphorylcholine Glycol Methacrylate 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 crosspolymer made from phosphorylcholine (a component of cell membranes) and methacrylate groups. It forms a hydrogel-like network when applied to the skin.
How it works
When applied, it spreads into a thin, flexible film that adheres to the skin's surface. The phosphorylcholine groups attract and hold water, providing a moisturizing effect, while the crosslinked structure prevents the film from washing away easily. This helps reduce transepidermal water loss (TEWL) and leaves skin feeling smooth and hydrated.
Pros
Mimics natural skin structure
The phosphorylcholine group is similar to components in your cell membranes, making the ingredient feel very compatible and less likely to cause irritation.
Lightweight hydration
Unlike heavy oils or waxes, this polymer forms a breathable film that hydrates without feeling greasy or heavy on the skin.
Cons and cautions
Synthetic origin
It is made in a lab, which may be a turn-off for those seeking all-natural or organic skincare products.
Limited independent research
Most studies are funded by manufacturers, so there is less independent data on long-term effects compared to classic humectants like glycerin.
Best for
- People with dry or dehydrated skin looking for extra hydration
- Those with sensitive skin who want a gentle film-former
Use caution if
- Individuals who strictly avoid synthetic ingredients in their routine
Usage tips
Safety summary
Generally recognized as safe for topical use. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic concentrations.
Research notes
Studies show it effectively reduces water loss and improves skin hydration. Most evidence comes from manufacturer-sponsored research, but the mechanism is well-understood and consistent with other film-forming polymers.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions.
- Common uses
- Moisturizers, Serums, Sunscreens, Primers
- Environmental note
- As a synthetic polymer, it may not be biodegradable. However, it is used in low concentrations and is not known to accumulate in the environment.
Good to know
- This ingredient is often used in 'biomimetic' skincare that aims to copy the skin's natural chemistry.
- It is considered non-comedogenic and safe for most skin types.
