What it is
An extract derived from the leaves or stems of Chloranthus japonicus, a perennial herb used in traditional medicine. It contains various plant compounds like flavonoids and phenolic acids.
How it works
The extract is thought to work by providing antioxidant compounds that can neutralize free radicals, which are unstable molecules that can damage skin cells. It may also have mild anti-inflammatory effects, helping to reduce redness or sensitivity when applied topically.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for most skin types, including sensitive skin.
Natural antioxidant
Derived from a plant source, it offers a mild defense against free radicals from pollution and UV exposure.
Cons and cautions
Limited evidence
Most research is lab-based or traditional; there are few human studies confirming its benefits in skincare.
Not a standalone solution
It works best as part of a broader antioxidant blend, not as a primary active ingredient.
Best for

- People with normal to combination skin who want extra environmental protection
Use caution if
- Those with known allergies to Chloranthus or related plants
