Product details
Tea polyphenols: Their main functions in cosmetics include whitening, anti-oxidation, anti-aging, anti-inflammatory and anti-allergic.
Tea polyphenols can inhibit the activity of tyrosinase, thereby reducing the synthesis of melanin and achieving the effect of whitening the skin. In addition, tea polyphenols can remove free radicals, protect cells from oxidative damage, and delay skin aging. Tea polyphenols also have a certain anti-inflammatory effect, which can reduce inflammatory reactions and relieve symptoms such as skin redness, swelling, and itching. Its anti-allergic effect is reflected in inhibiting the release of histamine by mast cells, thereby alleviating allergic symptoms.
