Zinc Dimethicone PEG-8 Succinate
INCI: ZINC DIMETHICONE PEG-8 SUCCINATE
A silicone-based ingredient that helps products spread smoothly and leaves a soft, matte finish on skin.
In plain English
Zinc Dimethicone PEG-8 Succinate is a modified silicone that combines the smoothing, water-resistant properties of silicones with the oil-absorbing benefits of zinc. It forms a thin, breathable film on the skin that helps makeup last longer and reduces shine without feeling heavy or greasy. The 'PEG-8' part makes it slightly water-soluble, so it rinses off more easily than traditional silicones.

Quick decision guide
Useful, but context matters
Zinc Dimethicone PEG-8 Succinate 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 Zinc Dimethicone PEG-8 Succinate.
- 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 semi-synthetic polymer created by chemically linking dimethicone (a silicone) with zinc and PEG-8 succinate. It appears as a white to off-white powder or waxy solid in its raw form.
How it works
When applied, it spreads into an even, flexible film that sits on the skin's surface. This film helps other ingredients stay in place, reduces water loss from the skin, and gives a soft-focus effect that blurs pores and fine lines. The zinc component provides mild oil absorption and a matte appearance.
Pros
Smooth, silky texture
Creates a velvety feel on skin that helps makeup glide on evenly and reduces the appearance of pores.
Matte finish without dryness
Absorbs excess oil and reduces shine, but the silicone film helps maintain skin comfort, unlike some powders that can feel chalky.
Cons and cautions
May be drying for some
The matte effect can leave very dry or dehydrated skin feeling tight or flaky, especially if used in high concentrations.
Requires double cleansing
Because it forms a water-resistant film, it may not rinse off with a gentle cleanser alone, requiring an oil-based cleanser or micellar water first.
Best for
- People with oily or combination skin looking for a matte finish
- Anyone who wants makeup to stay put longer
Use caution if
- Those with very dry or dehydrated skin may find it too mattifying
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The PEG component is well-tolerated, and zinc levels are low enough to avoid irritation. Rare reports of sensitivity in very reactive skin.
Research notes
Limited independent studies on this specific compound, but its components (dimethicone, PEG, zinc) have a long history of safe use in cosmetics. The Cosmetic Ingredient Review (CIR) panel has reviewed similar silicone polymers and found them safe as used.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and most other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Primers, Foundations, Sunscreens, Moisturizers
- Environmental note
- As a silicone derivative, it is not readily biodegradable. However, its PEG modification may improve its environmental profile compared to unmodified silicones. Look for brands that address silicone sustainability.
Good to know
- This ingredient is often used in 'long-wear' and 'transfer-resistant' makeup formulas.
- The PEG-8 modification makes it less occlusive than pure dimethicone, so it feels lighter on the skin.
- Zinc in this form is not the same as zinc oxide used in sunscreens; it does not provide UV protection.
