Science
Mechanism of Action
This ingredient functions as a biomimetic liquid wax ester, remarkably similar to the wax esters comprising 25-30% of human sebum. This allows it to effectively regulate the skin's natural oil production, potentially reducing excess sebum. It establishes a breathable, semi-occlusive barrier on the skin surface, minimizing trans-epidermal water loss, while also permeating hair follicles and pores. Internally, it integrates with existing sebum and delivers essential moisture to the intercellular spaces of the stratum corneum, reinforcing the skin barrier. Its inherent fatty acids, vitamins (A, B complex), and potent antioxidants (Vitamin E, phenolic compounds) provide significant anti-inflammatory, soothing, and regenerative benefits, furthermore assisting in dissolving follicular sebum deposits and clearing comedones.

Stability
Jojoba oil exhibits exceptional stability, attributed to its unique wax ester structure, which imparts high resistance to rancidity and thermal degradation. It boasts an oxidative stability index of approximately 60. Note that refined versions may have reduced oxidative stability due to the absence of inherent antioxidants.
Conflicts
- Oxidizing agents (e.g., nitrates, oxidizing acids, chlorine bleaches) as these combinations may pose an ignition risk.
