Shunkokan Peel Extract
INCI: Citrus Shunkokan Peel Extract
A gentle citrus peel extract that may help protect skin from environmental stress, though research is still early.
In plain English
This is an extract made from the peel of the Shunkokan, a type of Japanese citrus fruit. In skincare, it's used mainly for its antioxidant content, which can help neutralize free radicals from pollution and UV exposure. Because it comes from citrus peel, it also contains natural oils and flavonoids that may soothe and condition the skin. It's generally considered gentle, but like any plant extract, it can vary in potency depending on how it's processed.
