Science
Mechanism of Action
Hevea Brasiliensis Seed Oil exerts its effects through several pathways. It acts as a potent antioxidant, neutralizing active oxygen free radicals and inhibiting lipid peroxidation, thereby safeguarding skin cells. The oil stimulates cell proliferation and collagen synthesis while suppressing Matrix Metalloproteinase-2 (MMP-2), collectively supporting skin rejuvenation and decelerating aging processes. Its rich profile of linolenic and linoleic acids, essential polyunsaturated fatty acids, improves skin cell membrane fluidity, which may mitigate issues such as skin discoloration, acne, and wrinkles. Additionally, it forms a protective moisture barrier, helps regulate natural hydration, and provides soothing relief through potential anti-inflammatory actions, reducing redness and discomfort. Biochemical mechanisms also include stimulating cellular antioxidant activity in dermal papilla cells and inhibiting 5α-reductase.

Key findings
- 01 In vitro studies demonstrate non-cytotoxicity in HaCaT and human dermal fibroblast cells at concentrations up to 0.1 mg/mL.
- 02 It stimulates cell proliferation, enhances antioxidant activity, promotes collagen production, and suppresses MMP-2, contributing to anti-aging effects.
- 03 Proven safe on human follicle dermal papilla cells and DU-145 human prostate carcinoma cells at concentrations between 0.1-100 µg/mL, showing comparable antioxidant potency to minoxidil and vitamin C.
- 04 Exhibits 5α-reductase inhibitory activity.

The Formula
Formulation
Stability
The oil demonstrates notable stability, maintaining its quality with minimal changes in acid and peroxide values for approximately one year when stored in the dark at room temperature. This is attributed to its natural content of antioxidants like vitamin E, flavones, and phenols. Its fatty acid composition further supports thermal stability and a slow oxidation rate, with polyunsaturated fatty acids remaining stable in samples for 8 weeks.
Conflicts
- Potential saponification when combined with strong alkaline agents (e.g., sodium hydroxide) in high pH formulations, due to its free fatty acid content (up to 23.68%).
Safety
Safety Profile
Comprehensive cytotoxicity assessments confirm that Hevea Brasiliensis Seed Oil is safe for topical application to human skin, showing non-cytotoxicity in HaCaT cells, human dermal fibroblasts, human follicle dermal papilla cells, and DU-145 human prostate carcinoma cells at tested concentrations up to 0.1 mg/mL. Animal toxicological tests over 3 months indicated no toxic potential, and the extracted oil has been verified free of hazardous compounds like linamarin. Official CIR, SCCS, or FDA regulatory statuses are currently unavailable.
