Green Tea Leaf Extract

Green tea leaf extract, sourced for iS Clinical formulas from Japanese green tea, is rich in catechins such as EGCG. These antioxidants support the skin's defences against pollution and other everyday stressors, while the extract's calming character suits skin prone to redness or sensitivity. It also helps oily areas look more balanced without leaving skin feeling stripped.

Three iS Clinical products include it, each at a point in the routine where comfort matters. Warming Honey Cleanser uses it at the Cleanse step. Moisturizing Complex, a daily moisturiser, carries it into the Hydrate step. Hydra-Intensive Cooling Mask offers a more concentrated Hydrate moment when skin feels dry, tight or warm.
