What it is
An extract derived from the leaves of Coniogramme japonica, a fern native to East Asia. It contains flavonoids and other polyphenolic compounds believed to have antioxidant and anti-inflammatory activity.
How it works
The polyphenols in the extract can neutralize free radicals (unstable molecules that damage skin cells), potentially reducing oxidative stress. Some compounds may also calm inflammatory pathways, helping to reduce redness and sensitivity.
Pros

Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Antioxidant support
Helps protect skin from environmental stressors like pollution and UV-induced free radicals.
Cons and cautions
Limited research
Most evidence comes from lab studies; human clinical trials are scarce, so benefits are not fully proven.
