What it is
A botanical extract derived from the fern Botrychium ternatum, containing flavonoids and other polyphenolic compounds that act as antioxidants.
How it works
It provides antioxidant activity by neutralizing free radicals, which are unstable molecules that can damage skin cells. It also has soothing properties that may help reduce redness and irritation when applied topically.

Soothing potential
May help calm minor redness or irritation, offering a comforting effect for skin that is easily aggravated by environmental factors.
