Science

Mechanism of Action

This extract functions primarily through its rich content of antioxidants, including polyphenols like anthocyanins and ellagitannins, as well as vitamins C and E and ellagic acid. These components effectively neutralize free radicals, mitigating oxidative stress and combating premature skin aging. Its anti-inflammatory properties, attributed to ellagic acid, quercetin, and anthocyanins, reduce redness and irritation, promoting a calmer complexion. Rubus Idaeus Fruit also enhances skin hydration by supporting moisture balance and strengthening the skin barrier, which helps diminish fine lines and prevent transepidermal water loss. Additionally, it offers mild keratolytic and purifying effects, promoting smoother skin texture. The vitamin C content stimulates collagen synthesis, improving skin firmness, while also contributing to a brighter, more even skin tone by addressing discoloration. Topical application has been shown to bolster skin's defenses against UVB-induced damage.
