JAPANESE GREEN TEA

Camellia Sinensis Leaf Extract

Japanese Green Tea, Camellia Sinensis Leaf Extract

Green Tea has been treasured in Japan for centuries, but within its delicate leaves is some remarkably sophisticated skin chemistry. Green Tea is exceptionally rich in polyphenols called catechins, including its most celebrated compound, EGCG—epigallocatechin gallate—one of the most extensively studied botanical antioxidants in skincare.

EGCG helps neutralize free radicals generated by UV exposure, pollution and other environmental stressors. This matters because the visible effects of environmental damage are cumulative. Day after day, oxidative stress can contribute to the breakdown of collagen and elastin and interfere with healthy skin function. Years later, that accumulated damage can become visible as fine lines, wrinkles, loss of firmness and elasticity, rougher texture, uneven tone and dullness. Green Tea has been studied directly on human skin in relation to UV-induced damage, while laboratory research has examined EGCG's effects on inflammatory pathways and enzymes involved in collagen degradation. Its value isn't that it suddenly creates younger skin; it's that it helps defend against some of the processes that gradually make skin look older.

With consistent use, antioxidant protection becomes a long-game strategy. By helping limit repeated oxidative stress, Green Tea supports skin in maintaining a smoother, firmer, more resilient and more even-looking appearance over time. Its anti-inflammatory activity also helps calm environmental stress that can leave skin looking irritated, tired or depleted. That is what makes EGCG so valuable in body care. We moisturize because we can immediately feel dryness, but we don't necessarily see oxidative damage accumulating while it's happening. Green Tea adds a protective dimension to The Signature Body Butter™—caring not only for how the skin feels today, but for how beautifully it can age.

In The Signature Body Butter™, Japanese Green Tea provides EGCG-rich antioxidant defense against cumulative environmental stress, complementing the deep nourishment of Shea, carotenoid-rich Buriti, Pomegranate's visible-aging story and the barrier support of Ceramides.
