Science

Mechanism of Action

RUBUS HIRSUTUS FRUIT/LEAF EXTRACT functions via its high concentration of polyphenols, vitamins C and E, and various minerals. These compounds confer robust antioxidant defense against environmental aggressors like UV radiation and pollution, alongside potent anti-inflammatory properties. The extract contributes to reducing hyperpigmentation, improving skin luminosity, and refining skin texture. It also supports barrier function through hydrating effects, modulates sebum production via an astringent action, and offers gentle keratolytic and purifying properties to minimize redness and irritation. Additionally, its ellagic acid content may attenuate collagen degradation, contributing to anti-aging benefits.
