What is the role of green tea extract in skin care products?

Green tea extract in skin care products has anti-oxidative and anti-inflammatory effects, which can not only delay aging and prevent dullness, but also repair inflammation to a certain extent, making the skin fair and clear all day.

The anti-aging effect of green tea extract mainly comes from the powerful antioxidant effect of tea polyphenols. The aging of our daily bodily functions or skin is an oxidative process. A large number of free radicals are produced in our metabolism, and these free radicals not only damage cells but also make us age. The tea polyphenols rich in green tea can improve the body's ability to fight free radicals and slow down the speed of aging.

As a reducing agent, tea polyphenols can also inhibit the activities of tyrosinase and catalase that cause skin blackening, freckles, brown spots and age spots, thereby effectively inhibiting the production of pigment. Therefore, green tea has an obvious effect on skin whitening.

In addition to its role in skin care products, green tea extract can also be used in health care products:

Tea polyphenols can significantly reduce serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels in hyperlipidemia, and at the same time have the effect of restoring and protecting vascular endothelial function. The hypolipidemic effect of tea polyphenols is also one of the main reasons why tea can make obese people lose weight without rebounding.

Alcohol-induced liver damage is mainly caused by free radical damage caused by ethanol. As a free radical scavenger, tea polyphenols can inhibit alcohol-induced liver damage.

Serious environmental pollution has obvious toxic effects on human health. Tea polyphenols have a strong adsorption effect on heavy metals, and can form complexes with heavy metals to produce precipitation, which is beneficial to reduce the toxic effects of heavy metals on the human body. In addition, tea polyphenols also have the effect of improving liver function and diuresis, so they have a good anti-solution effect on alkaloid poisoning.

By increasing the total amount of human immunoglobulin and maintaining it at a high level, tea polyphenols stimulate changes in antibody activity, thereby improving the overall immune capacity of the human body and promoting the body's self-conditioning function.
