Our take
Is Hypericum Perforatum (St. John's Wort) Leaf Extract a Good Ingredient?
Rated Fair because the plant polyphenols may offer soothing and antioxidant support, but the data is limited and extract composition varies. It also contains photosensitizing constituents such as hypericin that can raise irritation and sun-sensitivity risk, which is enough to keep it out of Good territory.
