tea is one of the most popular tea beverages in the world, particularly in
Asian countries. Green tea is derived from the leaves of the plant Camellia

green tea, its extract also offers skincare benefits.

- Has anti-inflammatory and soothing properties which help lessen redness and itching associated with irritated skin.
- Has astringent properties which help tone the skin to reduce the appearance of pores and regulate sebum production.
- Has anti-cellulite properties (due to its 2 to 4% caffeine content) which help reduce the appearance of cellulite by improving the skin tone.

Formulation
Tips
- Typical usage rate is 1 – 5% (for liquid extract), up to 6% (for oil extract) and 0.5 – 1% (for powdered extract).
- Add to the cool down phase of the formulation because high temperature can reduce the antioxidant activity of green tea extract.
- For powdered green tea extract, dissolve it first in slightly warm water before adding to the cool down phase.
- Maintain the final pH of the formulation between 4 and 6. Extremely low or extremely high pH can degrade the catechins in green tea extract.
