Science
Mechanism of Action
This extract operates through several distinct mechanisms: its richness in oenothein B specifically inhibits 5α-reductase, an enzyme central to sebum synthesis, thereby regulating oiliness. It actively modulates the skin's microbiota, promoting beneficial commensals and reducing porphyrins associated with C. acnes, leading to a healthier skin environment. Furthermore, it demonstrates senolytic activity on dermal fibroblasts, aiding in the reduction of aging signs, while its flavonoids and phenolic acids provide antioxidant and anti-inflammatory effects that soothe irritation and reduce redness. It also functions as a skin conditioning agent, helping prevent dehydration.

Dusting Analysis
Clinical studies validate efficacy at concentrations as low as 0.001% for anti-aging benefits, with significant sebum regulation observed at 3%. These effective percentages are within typical cosmetic formulation ranges, indicating that the ingredient is not commonly used at sub-efficacious "dusting" levels.
