Camellia sinensis leaf extract comes from the green tea plant and is an abundant source of bioactive compounds that have been shown to offer significant benefits to our skin.

In the outermost layer of skin, the stratum corneum, tea extracts provide strong antioxidant activity by strengthening blood vessels and increasing microcirculation.

In the deeper skin layers, tea polyphenols provide UV radiation protection by absorbing UVB light and acting on various enzymes. These effects can delay skin ageing by downregulating enzymes responsible for degrading hyaluronic acid, lipids, collagen, and elastin.

Tea polyphenols and catechins (EGCG being the most bioactive), also display antioxidant activity due to their free radical scavenging ability, decelerating the inflammatory process.
