Ingredient review
Polysilicone-20
INCI: POLYSILICONE-20
Polysilicone-20 is a gentle silicone that helps products spread smoothly and leaves skin feeling soft without clogging pores.
In plain English
Polysilicone-20 is a type of silicone that forms a thin, breathable film on your skin. This film helps other ingredients spread more easily and gives your skin a smooth, silky feel. It's often used in moisturizers and primers to improve texture and reduce tackiness. Because it's non-comedogenic, it's unlikely to clog pores, making it suitable for many skin types, including oily and acne-prone skin.

Quick decision guide
Useful, but context matters
Polysilicone-20 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 Polysilicone-20.
- 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
Polysilicone-20 is a synthetic silicone polymer. It is a clear, viscous liquid that is designed to create a flexible, water-resistant film on the skin or hair. It is part of a family of silicones known for their smooth feel and stability.
How it works
When applied, Polysilicone-20 spreads into a thin, even layer that fills in fine lines and uneven texture. This film helps lock in moisture, reduces friction, and creates a barrier that can protect the skin from environmental stressors. It also improves the sensory feel of a product, making it glide on smoothly without a greasy residue.
Pros
Smooth texture
Polysilicone-20 gives products a silky, non-greasy feel, making them pleasant to apply and helping makeup glide on smoothly.
Pore-friendly
It has a low comedogenic rating, meaning it is unlikely to clog pores, which is great for acne-prone or oily skin types.
Cons and cautions
Silicone sensitivity
Some people prefer to avoid silicones due to personal preference or concerns about buildup, though Polysilicone-20 is generally well-tolerated.
Limited research
Compared to more common silicones like Dimethicone, there is less published research specifically on Polysilicone-20, though it is considered safe based on its chemical class.
Best for
- People with normal to oily skin looking for a smooth, matte finish
- Those who want a primer-like effect from their moisturizer
Use caution if
- Individuals who strictly avoid silicones in their skincare routine
Usage tips
Safety summary
Polysilicone-20 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. As with all silicones, it is well-tolerated by most skin types, though individuals with very sensitive skin may want to patch test first.
Research notes
While specific studies on Polysilicone-20 are limited, it belongs to a well-studied class of silicone polymers. These are generally recognized as safe by cosmetic ingredient review panels. Research supports their use as effective film-formers and skin conditioners with minimal risk.
Common label clues
- Typical concentration
- Typically 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. It is not classified as a hazardous substance under normal use conditions.
