Ingredient review
Dimethicone/Polyglycerin-3 Crosspolymer
INCI: Dimethicone/Polyglycerin-3 Crosspolymer
A gentle silicone gel that smooths skin and adds a touch of hydration without feeling heavy or greasy.
In plain English
This ingredient is a special type of silicone that has been chemically linked with a moisturizing compound (polyglycerin). The result is a soft, gel-like substance that spreads easily on the skin, leaving a silky, non-greasy feel. It helps other ingredients stay on the skin longer and can provide a light, cushiony texture in products like primers and moisturizers. Unlike some silicones that only sit on top of the skin, this one also offers a mild hydrating effect because of the polyglycerin part.

Quick decision guide
Useful, but context matters
Dimethicone/Polyglycerin-3 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 Dimethicone/Polyglycerin-3 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 polymer made by crosslinking dimethicone (a common silicone) with polyglycerin-3 (a humectant derived from glycerin). This creates a three-dimensional gel network.
How it works
When applied, it forms a thin, breathable film on the skin's surface. This film smooths out fine lines and uneven texture, helps lock in moisture, and gives a soft-focus effect. The polyglycerin component attracts water to the skin, adding a light hydrating boost.
Pros
Smooth, silky texture
Creates a velvety, non-sticky feel on the skin, making it ideal for primers and lightweight moisturizers.
Light hydration boost
Unlike many silicones, it offers a mild humectant effect, helping to attract and hold a small amount of moisture.
Cons and cautions
May require double cleansing
Because it forms a film, it can be resistant to water-based cleansers. An oil-based cleanser or micellar water may be needed for thorough removal.
Not for silicone-avoiders
If you prefer a silicone-free routine, this ingredient is not a fit, as it is a silicone-based polymer.
Best for
- People with normal to dry skin looking for a smooth, non-greasy moisturizer or primer
- Those who want a lightweight texture that still provides a bit of hydration
Use caution if
- Individuals who strictly avoid silicones in their skincare routine
Usage tips
Safety summary
Dimethicone/Polyglycerin-3 Crosspolymer is considered safe for use in cosmetics. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin. No significant safety concerns have been reported in cosmetic use.
Research notes
Research on this specific crosspolymer is limited, but it is a well-established ingredient in the cosmetics industry. Its safety is supported by the broader safety profile of dimethicone and polyglycerin derivatives, both of which are widely used and considered safe. The Cosmetic Ingredient Review (CIR) has reviewed similar silicone polymers and found them safe for use.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (USA) and the EU Cosmetics Regulation. No known restrictions.
- Common uses
- Moisturizers, Serums, Primers, Sunscreens
- Environmental note
- As a silicone-based polymer, it may not be biodegradable. However, its environmental impact is considered lower than some other silicones due to its crosslinked structure, which reduces bioaccumulation potential.
Good to know
- This ingredient is often used in 'waterless' or anhydrous formulas because it can help stabilize them.
- It is considered non-comedogenic and generally safe for sensitive skin.
