Ingredient review
Green Tea Leaf Extract
INCI: Camellia sinensis leaf extract
A well-researched antioxidant that helps protect skin from environmental damage and soothes irritation.
In plain English
Green tea leaf extract is a natural ingredient made from the leaves of the Camellia sinensis plant. It's packed with compounds called polyphenols, especially EGCG, which help neutralize free radicals—unstable molecules that can damage skin cells and speed up aging. In skincare, it works like a shield against pollution and UV stress, while also calming redness and inflammation. Think of it as a gentle, protective tonic for your skin.

What it is
Green tea leaf extract is a water-soluble extract derived from unfermented leaves of Camellia sinensis. It contains high levels of catechins, particularly epigallocatechin gallate (EGCG), along with caffeine and vitamins B and E.
How it works
The catechins in green tea act as antioxidants, scavenging free radicals generated by UV exposure and pollution. They also have anti-inflammatory effects by inhibiting certain enzymes (like COX-2) and reducing redness. Additionally, green tea can help regulate sebum production and provide mild antimicrobial activity.
Pros
Strong antioxidant protection
Green tea's catechins neutralize free radicals, helping to prevent premature aging and support skin health.
Calms irritation
Its anti-inflammatory properties can reduce redness and soothe sensitive or reactive skin.
Cons and cautions
Stability concerns
Green tea extract can degrade quickly when exposed to air or light, so it requires careful formulation to remain effective.
Potential for irritation
While generally gentle, high concentrations may cause mild stinging or redness in extremely sensitive skin.
Best for
- Anyone looking to boost antioxidant protection in their routine
- People with dull or stressed skin from pollution or sun exposure
- Those with oily or combination skin seeking balance
Use caution if
- Individuals with a known allergy to green tea or its components
