Science
Mechanism of Action
This oil acts by creating a robust lipid barrier on the skin's surface, which demonstrably reduces transepidermal water loss, thereby optimizing hydration and supporting a more youthful, plump appearance. It is rich in critical essential fatty acids, specifically linoleic and alpha-linolenic acids, which integrate into the intercellular lipid bilayers, fostering ceramide synthesis and fortifying skin barrier integrity. Furthermore, its high concentrations of tocopherols (Vitamin E) and carotenoids (Vitamin A) provide potent antioxidant defense against oxidative damage from UV exposure and environmental pollutants, crucial for sustaining collagen structure. The presence of phytosterols and polyphenols also modulates inflammatory pathways, diminishing inflammatory cytokine expression, skin reactivity, and symptoms like itching, swelling, and redness. Additionally, it exhibits inherent antimicrobial properties.

The Formula
Formulation
Stability
Rubus Strigosus Seed oil exhibits high sensitivity to oxidation. For optimal stability, it should be stored in a cool environment, preferably refrigerated, in its original, sealed packaging, away from air and light, ensuring a shelf life of 6-8 months after opening. Formulations incorporating this oil would greatly benefit from the inclusion of synergistic antioxidants and protective packaging to mitigate degradation.
Synergies
- Antioxidants (e.g., Vitamin E, Ferulic Acid) for enhanced stability and free radical scavenging.
- Other emollient oils in sun care formulations to achieve broader SPF contributions.
Safety
Safety Profile
