What is Jojoba?
Jojoba is a shrub native to North America. Its oil, which is extracted from the seeds, is quite unique because it is not actually an oil but a wax ester. An oil is a triglyceride, which means it is a molecule of glycerin + 3 fatty acids attached to it. This structure easily breaks down through hydrolysis. On the other hand, a wax ester is a long molecule composed of a fatty acid + a fatty alcohol. Wax esters are designed to form a protective and moisturizing barrier, for example, on plant leaves to protect them.
Properties of Jojoba Oil
Jojoba oil, being the most similar to human sebum (both are wax esters), blends with it and forms a thin, non-greasy, and semi-occlusive layer. This layer is then absorbed into the skin and diffuses into the intercellular spaces, making the skin softer and more flexible. It has anti-inflammatory and regenerative properties and helps alleviate dryness, flakiness, and itching while regulating the skin's oil levels.
