What it does
- Provides antioxidant protection against environmental and UV stress.
- Soothes and helps calm redness.
- Helps balance oily and blemish-prone skin.
How it works
Green tea's benefits come mainly from catechin polyphenols, especially epigallocatechin gallate (EGCG), which are widely documented for antioxidant, soothing and sebum-balancing activity. Potency depends on the extract's standardised polyphenol/EGCG content.
Use level
- Typical use level
- typically 0.5–5% (extract)
Whole extracts are commonly used at 0.5–5% depending on standardisation. Standardised polyphenol content matters more than raw extract percentage.
Formulation considerations
- Choose a grade matched to your phase; check standardised polyphenol content.
- Polyphenols can oxidise and darken; antioxidants and suitable packaging help.
- Generally robust and broadly compatible.
What it pairs with & what to avoid
Pairs well with
- Niacinamide
- Centella and allantoin (soothing)
- Antioxidant networks
Use with care / avoid
- Assuming all green tea extracts are equivalent — potency varies
Regulatory status
Camellia sinensis leaf extract is listed in the EU CosIng database and is a well-established botanical ingredient.
