Ingredient review
Ethyl Gallate
INCI: ETHYL GALLATE
Ethyl Gallate is a gentle antioxidant that helps protect skin from free radicals, but it is less studied than more common antioxidants like vitamin C or E.
In plain English
Ethyl Gallate is a molecule made from gallic acid, a natural compound found in plants like oak bark and tea leaves. In skincare, it works as an antioxidant, meaning it helps neutralize unstable molecules called free radicals that can damage skin cells and speed up aging. It is often added to products to boost their protective power against pollution and UV exposure, though it is not a sunscreen itself. Think of it as a helper ingredient that supports your skin's defense system.

Quick decision guide
Useful, but context matters
Ethyl Gallate 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 Ethyl Gallate.
- 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
Ethyl Gallate is the ethyl ester of gallic acid, a polyphenol found in many plants. It is produced semi-synthetically for use in cosmetics as a stable antioxidant.
How it works
Ethyl Gallate works by donating electrons to neutralize free radicals, preventing them from oxidizing and damaging skin lipids, proteins, and DNA. This helps reduce oxidative stress and supports the skin's natural repair processes.
Pros
Gentle antioxidant
Ethyl Gallate is well-tolerated by most skin types and provides a mild boost in protection against free radicals without causing irritation.
Stable in formulations
Unlike some antioxidants that degrade quickly, Ethyl Gallate remains stable in many cosmetic formulas, ensuring longer shelf life and consistent efficacy.
Cons and cautions
Less researched
Compared to antioxidants like vitamin C or niacinamide, Ethyl Gallate has fewer human studies supporting its benefits for skin aging or brightening.
Potential for mild irritation
In high concentrations or for very sensitive skin, it may cause slight redness or stinging, though this is rare.
Best for
- People looking for extra antioxidant protection in their routine
- Those with normal to dry skin who want a gentle protective ingredient
Use caution if
- Individuals with known allergies to gallic acid derivatives or plant polyphenols
Usage tips
Safety summary
Ethyl Gallate is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, but individuals with very sensitive skin or allergies to polyphenols should patch test first.
Research notes
Research on Ethyl Gallate in skincare is limited but promising. Studies show it has antioxidant and anti-inflammatory properties in lab settings, but more human clinical trials are needed to confirm its efficacy for anti-aging or skin protection.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has not issued a specific safety assessment for Ethyl Gallate, but it is generally recognized as safe at low concentrations.
- Common uses
- Serums, Moisturizers, Anti-aging creams
- Environmental note
- Ethyl Gallate is semi-synthetic, derived from natural gallic acid, and is considered biodegradable. Its production has a moderate environmental footprint compared to fully synthetic antioxidants.
Good to know
- Ethyl Gallate is often listed near the end of ingredient lists, indicating it is used in low concentrations.
- It is sometimes used as a preservative booster in cosmetics, though its primary role is antioxidant.
