Jojoba oil is actually a liquid wax extracted from the seeds of the jojoba plant (Simmondsia chinensis), a shrub native to the arid regions of North America. Its composition, mainly wax esters, closely resembles the skin's hydrolipidic film, making it a cosmetic vegetable oil of particular interest.
Its biomimetic structure allows skin integration without greasy effect, with good documented tolerance for all skin types. It is associated, according to available data, with a natural affinity for the skin's sebum film, a property that helps its adaptation to dry skin as well as combination or blemish-prone skin.
Its humectant profile is documented to contribute to preserving skin hydration comfort and limiting water loss. Jojoba oil is also documented for its richness in vitamin E and antioxidants, linked to protection against oxidative stress, one of the factors contributing to visible signs of aging.
It is recognized for contributing to skin comfort, visible suppleness, and documented soothing properties, for softer, more comfortable-looking skin daily.
Its natural stability against oxidation, higher than many vegetable oils, also makes it an ingredient of interest in cosmetic formulation for formula stability.
In summary, a naturally derived liquid wax, well tolerated and widely documented, associated with skin comfort, visible suppleness, and antioxidant protection.
