Science

Mechanism of Action

This extract is rich in phenolic acids and coumarins, including fraxin and aesculetin, which collectively drive its antioxidant and anti-inflammatory actions. It effectively scavenges free radicals and inhibits key enzymes such as tyrosinase, elastase, and collagenase, contributing to anti-aging and skin tone balancing effects. Its draining and stimulating action on skin microcirculation specifically helps reduce the appearance of dark circles and puffiness under the eyes.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

A direct safety assessment by CIR or SCCS is not available. However, independent reviews indicate a low irritancy profile, with SkinSAFE classifying it as 'Irritant Free'. While an acute oral toxicity study on a related seed extract showed a high LD50 greater than 2500 mg/kg in rats, this specific data does not directly apply to topical bark extract. Dermal toxicity for the bark extract remains largely undetermined by some sources.
