What it is

Bidens tripartita extract is a natural ingredient derived from the flowers, leaves, and stems of the bur marigold plant. It contains compounds like flavonoids and polyphenols that are known for their antioxidant and anti-inflammatory activities.

How it works

In a cosmetic product, Bidens tripartita extract works by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells). This helps reduce oxidative stress, which can lead to premature aging. Its anti-inflammatory properties may also help soothe redness and irritation when applied topically.
