Lauryl Dimethicone PEG-15 Crosspolymer
INCI: LAURYL DIMETHICONE PEG-15 CROSSPOLYMER
A silicone polymer that improves product feel and spreadability without clogging pores.
In plain English
This is a silicone-based ingredient that helps skincare and makeup products feel silky and spread smoothly on your skin. It works by forming a very thin, flexible film that doesn't feel heavy or greasy. Think of it as a texture helper that makes your creams, sunscreens, or foundations glide on easily and leave a soft, non-sticky finish.

Quick decision guide
Useful, but context matters
Lauryl Dimethicone PEG-15 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 Lauryl Dimethicone PEG-15 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 (a crosslinked version of lauryl dimethicone with PEG-15) designed to control viscosity and improve the sensory feel of cosmetic products.
How it works
It forms a thin, breathable film on the skin that helps other ingredients spread evenly. It also thickens the product slightly, giving it a luxurious, creamy texture without making it sticky or heavy.
Pros
Silky texture without greasiness
It gives products a luxurious, smooth feel that glides onto skin, making it ideal for primers and sunscreens that need to spread evenly.
Low irritation and comedogenic risk
This ingredient is generally well-tolerated and unlikely to clog pores, making it suitable for most skin types, including sensitive and acne-prone skin.
Cons and cautions
Synthetic and not biodegradable
As a silicone-based polymer, it is not naturally derived and does not break down easily in the environment, which may be a concern for eco-conscious users.
May not suit silicone-free routines
If you prefer to avoid all silicones for personal or ethical reasons, this ingredient is not compatible with that preference.
Best for
- Anyone who wants a smooth, non-sticky finish from their moisturizer or primer
- People with normal to combination skin looking for a lightweight texture
Use caution if
- Those who strictly avoid all silicone-based ingredients
