We confirmed this ingredient's definition and its registered function in public regulatory databases, but found no published study data on how the ingredient itself acts on the skin (checked by KAIAN, September 2026). We will update this page if new reports appear.

An extract from the leaves of rocket (arugula), a Brassicaceae plant. Used to help keep skin healthy

Contains flavonol glycosides such as quercetin, isorhamnetin and kaempferol. Cell-culture reports describe activation of PPAR-alpha with increased filaggrin expression, increased cornified envelope formation in keratinocytes, and antioxidant activity. CosIng lists its function as SKIN CONDITIONING

Unconfirmed. No public data on human use levels and no use-concentration survey (e.g. CIR) have been found

Unconfirmed. No human study has been found

The evidence remains at the in vitro (cell culture) level; human efficacy and safety data are unconfirmed. Some papers do not clearly state the plant part used, so the material may not match the 'leaf extract' of the labelling name. It is a Brassicaceae plant, and IgE-mediated reactions after ingestion have been reported as case reports (sensitisation data for topical use are unconfirmed)
