Tea polyphenols: uv filter. After absorption by the skin, uv can dilate blood vessels, causing acute symptoms such as redness, swelling and blisters. Long-term exposure will cause melanosis in the epidermis and promote skin aging. When uv rays hit the dermis, they dry it out and form small cracks that appear on the outside as tiny wrinkles. Tea polyphenols are known as "uv filters" and are effective skin protectants. Polyphenols are a kind of natural products with strong absorption in ultraviolet light region. Tea polyphenols can directly absorb ultraviolet light and prevent ultraviolet damage to skin.

Free radicals are an important factor in aging, and ultraviolet light is the main source of free radicals in the skin. Radiation can cause biological molecules and water molecules in the body to split, produce a large number of free radicals and damage the skin. Tea polyphenols can remove free radicals induced by ultraviolet radiation, prevent free radicals from damaging cells, and better promote the growth of skin cells. In addition, tea polyphenols have the function of inhibiting lipid peroxidation, thus protecting the normal function of skin collagen and lipids and other biomolecules, delaying the aging of skin and the formation of wrinkles.

Tea polyphenols: Help moisturize. As much as 70 percent of skin cells are made up of water, and the amount of water in the epidermis plays a decisive role in how your skin looks. The loss of water in the skin can affect normal cell metabolism, making the skin dry and dark, and even lack of elasticity and fine lines.

Tea polyphenols are a natural moisturizer. Because it contains a large number of hydrophilic groups, it can easily absorb moisture from the air and keep the skin hydrated. Tea polyphenols also have the inhibitory activity of hyaluronidase, which will promote subcutaneous infusion, local storage of exudate or blood to accelerate the diffusion, so as to achieve deep moisturizing effect. In addition, tea polyphenol and sticky protein, polysaccharide, phospholipid etc. produce compound action, can make bulky pore contractive, make flabby skin convergent, tight send, reduce furrow thereby, make the skin shows exquisite feeling.
