A powerful antioxidant from green tea that helps protect skin from environmental damage and soothes irritation.
In plain English
Epigallocatechin gallate (EGCG) is a natural compound found in green tea. In skincare, it acts as a strong antioxidant, meaning it helps neutralize unstable molecules called free radicals that can damage skin cells and speed up aging.

What it is
EGCG is a type of catechin, a natural polyphenol abundant in green tea leaves. It is the most studied and active antioxidant in green tea, known for its ability to scavenge free radicals and reduce oxidative stress.
How it works
In a cosmetic product, EGCG works by donating electrons to neutralize free radicals before they can damage skin cells. It also inhibits certain enzymes that break down collagen and elastin, helping to maintain skin firmness. Additionally, it calms inflammation by reducing the production of pro-inflammatory molecules.
Pros
Strong antioxidant protection
EGCG is one of the most potent natural antioxidants, helping to defend skin against pollution, UV rays, and other environmental aggressors that cause premature aging.
Soothes irritation
Its anti-inflammatory properties make it helpful for calming redness and sensitivity, making it a good option for reactive skin types.
Cons and cautions
Stability challenges
EGCG can degrade quickly when exposed to air, light, or high pH, so it requires careful formulation to remain effective on the shelf.
Potential for mild stinging
In high concentrations or on very compromised skin, some users report a slight tingling or stinging sensation, though this is rare.
Best for
- Anyone looking to boost antioxidant protection
- People with oily or combination skin who want a lightweight antioxidant
- Those concerned with environmental aging
Use caution if
- Individuals with known allergy to green tea or catechins
Usage tips
Safety summary
EGCG is considered safe for topical use at typical cosmetic concentrations. It has low irritation and comedogenic potential. As with any ingredient, patch test if you have very sensitive skin.
Research notes
Numerous peer-reviewed studies support EGCG's antioxidant and anti-inflammatory effects on skin. Research also suggests it may help protect against UV damage and support collagen health, though more human trials are needed for some claims.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in most regions including the EU and US. Not regulated as a drug.
