Science

Mechanism of Action

Ribes Nigrum Fruit Extract is a potent source of vitamins, minerals, essential fatty acids, and a diverse array of antioxidants including vitamin C, flavonoids, polyphenols, and anthocyanosides. Its action on the skin is multifaceted: it provides robust antioxidant defense by neutralizing free radicals and shielding cells from UV and environmental damage, thereby mitigating signs of premature aging. Its anti-inflammatory properties help soothe irritation and reduce redness by modulating specific pro-inflammatory cytokines, notably interfering with IFN-γ signaling. Furthermore, its amino acids and essential fatty acids reinforce the skin's natural barrier, enhancing hydration. Natural AHAs contribute to gentle exfoliation and stimulate cellular turnover, revealing a smoother, more radiant complexion, while its significant vitamin C content supports collagen synthesis and aids in diminishing hyperpigmentation.
