Science
Mechanism of Action
This ingredient operates through several key pathways: it significantly inhibits pro-inflammatory cytokines and enzymes, notably modulating IFN-γ signaling, due to its content of flavonols and anthocyanins. Its potent antioxidant capacity combats free radical damage and oxidative stress, thereby preserving structural skin proteins like collagen and elastin and mitigating signs of premature aging. Natural alpha hydroxy acids (AHAs) present within the leaf water provide mild exfoliation, stimulating cellular renewal. Furthermore, it supports the skin's Natural Moisturizing Factor (NMF) for enhanced hydration, and its vitamin C content contributes to collagen synthesis. It also demonstrates potential for limiting sebum oxidation, beneficial for oily skin, and exhibits antimicrobial activity against Gram-positive bacteria and Candida albicans.

Safety Profile
While Ribes Nigrum Fruit Extract is reported as a safe, non-comedogenic ingredient approved for use without restrictions, specific comprehensive toxicity data (oral, dermal, inhalation) for 'Ribes Nigrum Leaf Water' itself are not yet fully determined by regulatory bodies like CIR. It is not currently listed in the FDA's Voluntary Cosmetics Reporting Program requiring further action. Patch testing is advised for individuals with extremely sensitive skin to ensure optimal tolerance.
