Ingredient review
Polysilicone-14
INCI: POLYSILICONE-14
Polysilicone-14 is a gentle film-forming silicone that helps products last longer and feel smooth, but it may not suit everyone who prefers silicone-free routines.
In plain English
Polysilicone-14 is a synthetic silicone ingredient that forms a thin, flexible film on your skin or hair. Think of it like a very lightweight, invisible shield that helps other ingredients stay put and makes the surface feel silky. It is commonly found in sunscreens to improve water resistance and in makeup to help it last all day without smudging. Because it is a large molecule, it sits on top of the skin rather than sinking in, so it is generally non-irritating and unlikely to clog pores.

Quick decision guide
Useful, but context matters
Polysilicone-14 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-14.
- 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-14 is a high-molecular-weight silicone polymer. It is a synthetic ingredient created by linking silicone units into a chain, which gives it film-forming and water-repellent properties. It is a clear, viscous liquid that dries to a flexible, breathable film.
How it works
When applied, Polysilicone-14 spreads into a thin, even layer that dries to form a flexible film. This film acts as a barrier that reduces water loss from the skin and helps other ingredients (like UV filters or pigments) stay in place longer. It also imparts a smooth, silky feel and can reduce the greasy or sticky sensation of other ingredients.
Pros
Boosts wear and water resistance
Polysilicone-14 forms a flexible film that helps sunscreens and makeup stay effective longer, even in humid conditions or during swimming.
Silky, non-greasy feel
It gives products a smooth, velvety texture without adding oiliness, making it pleasant for everyday use on skin and hair.
Cons and cautions
Requires thorough removal
Because it forms a film, Polysilicone-14 can be stubborn to wash off with just water or a gentle cleanser. A double cleanse (oil-based cleanser followed by water-based) is often needed to avoid buildup.
Not for silicone-free routines
If you avoid silicones for personal or environmental reasons, Polysilicone-14 is one to skip, as it is a synthetic silicone polymer.
Best for
- Anyone looking for long-wearing makeup or water-resistant sunscreen
- People with normal to oily skin who want a smooth, non-greasy finish
Use caution if
- Those who prefer silicone-free or minimalist skincare routines
Usage tips
Safety summary
Polysilicone-14 is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and no significant toxicity concerns have been identified at typical concentrations. As with any ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Research on Polysilicone-14 specifically is limited, but it belongs to a well-studied class of silicone film-formers. Studies on similar silicones show they are safe, non-irritating, and effective at improving water resistance and wear. The Cosmetic Ingredient Review has reviewed related silicone polymers and found them safe.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar silicone polymers and found them safe at typical use levels.
- Common uses
- Sunscreens, Long-wear makeup, Primers, Hair styling products
- Environmental note
- Silicones like Polysilicone-14 are synthetic and not biodegradable. However, they are generally considered low in toxicity to aquatic life. Some consumers choose silicone-free products for environmental reasons.
Good to know
- Polysilicone-14 is often combined with other silicones or film-formers to enhance its water-repelling properties.
- It is considered safe by major regulatory bodies when used in typical cosmetic concentrations.
