| Résumé : |
Green tea extracted via SWE produces a highly effective botanical active that is responsibly sourced and can provide a new twist on traditional green tea actives. The subcritical water extraction used yields a rich bioactive composition resulting in high biological efficacy. Green Tea supports skin barrier health with the restoration of key skin barrier building blocks, Caspase- 14 and filaggrin, which are important for barrier reinforcement and UV protection. With a healthy and intact skin barrier, skin is able to fight external aggressors and prevent the signs of oxidative stress. It also reduces Sunburn Cells more effectively than vitamin E after UV exposure. This Green Tea extract is a powerful active that can support antioxidation and protection claims and can be marketed as a fresh new take on conventional green tea that outperforms the gold standard, vitamin E. |
