Science
Mechanism of Action
This ingredient functions primarily as a gentle physical exfoliant due to its finely textured, fibrous structure. Beyond its abrasive action, it is a rich source of essential fatty acids, including linoleic and alpha-linolenic acids, vital for strengthening and repairing the skin's natural barrier. A potent blend of antioxidants, such as Vitamin E, polyphenols, and carotenoids, neutralizes free radicals, mitigating environmental damage and combating premature signs of aging. Furthermore, it possesses anti-inflammatory properties that help soothe irritation and reduce redness by modulating inflammatory pathways, contributing to overall skin health and resilience.

Key findings
- 01 While specific effective concentrations for RUBUS IDAEUS SEED POWDER in direct skin application studies are not widely available, related Rubus Idaeus Seed Oil is commonly incorporated in cosmetics at concentrations between 0.1% and 5.0%.
- 02 Extracts from Rubus idaeus seeds have demonstrated potent radical-scavenging and antioxidant capabilities in cell-based models, and have shown dose-dependent antiproliferative activity against cancer cell lines.
- 03 A liposoluble extract derived from Rubus idaeus cells was observed to enhance hydration and improve water homeostasis within skin cells, concurrently increasing the synthesis of extracellular matrix components. In vivo studies further confirmed its notable skin-hydrating capacity.
- 04 An ethanol extract of red raspberry offered protection against UVB-induced damage by activating Nrf2 signaling pathways and inhibiting inflammatory responses.

The Formula
Formulation
Stability
The powder itself contains oil-soluble components and is largely insoluble in water. Its associated oil is susceptible to oxidation, suggesting optimal preservation in cool, light-protected conditions (e.g., amber bottles). However, raspberry seed oil generally exhibits good resistance to oxidation and stability during storage.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of Rubus Idaeus (Raspberry) Seed Oil. The seed powder is generally considered non-toxic for cosmetic use. While rare, individuals with known sensitivities to raspberries or related botanical species are advised to perform a patch test prior to widespread application.
