EDGEWORTHIA CHRYSANTHA BARK EXTRACT.

Valuable / SKIN CONDITIONING

Edgeworthia chrysantha bark extract is a botanical ingredient recognized for its potent anti-inflammatory effects, attributed to naturally occurring coumarins. It also shows promising capabilities in skin brightening by inhibiting melanin production, alongside potential antioxidant benefits for overall skin health.

Summary

Skin Conditioning Anti-inflammatory Skin Brightening Antioxidant

Science

Mechanism of Action

This extract works by inhibiting inflammatory pathways through coumarins like edgeworin and edgeworosides A and C, which have demonstrated analgesic effects. Its skin brightening action stems from the inhibition of melanin production and tyrosinase activity. Furthermore, related species exhibit strong antioxidant activity, suggesting Edgeworthia chrysantha may also contribute to neutralizing free radicals, supporting skin resilience.
