Many products on the market now focus on green tea extracts, but due to the complexity of tea itself, tea from different sources and extraction methods will affect its function, and tea concept products on the market are also mixed. The core components of tea extract are catechins, the main components include catechin (Catechin, (+)-C), EC, EGC, ECG, GCG, EGCG, etc., of which EGCG has the highest content.
Catechins contain multiple polyphenol structures and have strong antioxidant capacity. In addition, catechins also have whitening, moisturizing and anti-aging effects.
As a reducing agent, tea polyphenols can inhibit the activities of tyrosinase and peroxidase in skin melanosis, freckles, brown spots, and age spots, thereby effectively inhibiting the production of pigment. Therefore, green tea extract has an obvious effect on skin whitening. At the same time, tea polyphenols in tea extracts are natural products with a moisturizing effect.
Green tea extract can endow daily terminal products with multiple functions such as antioxidant, anti-radiation, moisturizing and repairing, and anti-aging. It is a functional ingredient worthy of consideration in many cosmetics.
