RUBUS IDAEUS BUD EXTRACT.

This extract, though primarily studied from fruit and leaf, is understood to deliver its benefits through a rich profile of bioactive compounds including polyphenols, flavonoids, vitamin C, ellagic acid, and anthocyanins. These components collectively combat oxidative stress by neutralizing free radicals, which in turn helps to mitigate signs of aging and enhance skin brightness. Its anti-inflammatory properties soothe irritation, reduce redness, and calm inflammation. Furthermore, certain constituents like fatty acids contribute to maintaining skin hydration and reinforcing the natural skin barrier. Research on an oil-soluble Rubus idaeus leaf cell extract indicates its capacity to upregulate genes crucial for skin hydration (aquaporin 3, filaggrin, involucrin, hyaluronic acid synthase) and stimulate ceramide production via glucocerebrosidase, leading to improved skin hydration and elasticity. The extract also demonstrates potential to inhibit enzymes contributing to skin discoloration and firmness loss, offer protection against UVB-induced damage, and, due to its vitamin C content, provide mild exfoliating and purifying effects for a smoother complexion.
