What it is
An extract derived from the root of Lychnis cognata, a perennial herb native to East Asia. It contains compounds like triterpenoid saponins and flavonoids that are believed to have antioxidant and anti-inflammatory activity.
How it works
The extract's flavonoids and saponins are thought to neutralize free radicals (unstable molecules that can damage skin cells) and reduce the production of pro-inflammatory signals in the skin. This can help soothe redness and support the skin's natural barrier function.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Antioxidant support
Flavonoids in the extract help defend skin from daily pollution and UV-induced oxidative stress.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human trials confirming its benefits in real-world skincare.
Rare allergy risk
Though uncommon, individuals with plant allergies may experience mild irritation or contact dermatitis.
Best for
- Those with sensitive or easily irritated skin
- Anyone looking for a gentle, plant-based antioxidant
Use caution if
- Individuals with known allergies to plants in the Caryophyllaceae (carnation) family
