For anti-photoaging, why not try green tea extract?

Photoaging is one of the main causes of skin aging. The production of reactive oxygen species (ROS), the production of oxidative stress, and the damage of cellular DNA are the three major weapons of photoaging. How to effectively prevent photoaging has become a hot topic in the field of skincare, and a very popular ingredient in the field of skin care is tea extract. These substances can not only have a good antioxidant effect but also have a certain inhibitory effect on the DNA mutation of skin cells induced by ultraviolet rays.

For anti-photoaging, why not try green tea extract?

There are two main categories of tea extracts in the field of skin care: green tea extracts and black tea extracts. For unfermented green tea, fresh green tea extract (GTE) is rich in polyphenols that play a major antioxidant role. In fermented tea such as black tea, the main antioxidants are black tea polyphenols composed of thearubigin, theaflavin and theabrownin. Green tea polyphenols (GTPs) are mixtures with good antioxidant properties and are composed of four major groups of active substances: catechins, procyanidins, phenolic acids and flavonoids.

A study showed that green tea extract-green tea polyphenols have a good inhibitory effect on erythema caused by ultraviolet light, and EGCG in green tea polyphenols has a good inhibitory effect on the activation of green factor NF-κB activity in some animal and human cell studies, which has a certain anti-inflammatory effect, can protect skin cells from the adverse effects of ultraviolet radiation, thereby achieving an anti-photoaging effect.

In daily life, we can not only choose skin care products containing green tea extract to fight against photoaging but also can achieve anti-aging by drinking a certain amount of green tea.
