Abstract: Jojoba oil is a natural oil derived from the seed of the Chinensis plant, which is a drought-resistant shrub native to southern Arizona, California, and Mexico. While its popularity in beauty products is a relatively new phenomenon, it has been used for centuries.
It is one of the few plants that produce wax esters that are nearly identical to those found in our skin. Our skin is composed of natural wax esters (known as sebum), which lock in moisture to keep our skin looking healthy and hydrated. As we age, our sebum production decreases, resulting in fine lines, dry skin, and sagging. The Jojoba plant produces wax esters that are identical to our sebum and is high in omega 6 and 9 fatty acids, as well as vitamins A, D, and E.
The significant increase in serum fatty acid levels after topical application of jojoba oil sheds new light on the oil's potential uses in promoting neonatal growth, improving geriatric nutrition, enhancing athletes' endurance during exercises, treating acne, its anti-inflammatory properties that help soothe skin; skin hydration; antioxidant protection; and skin softness. There are no significant disadvantages to using this ingredient in general.
A study was conducted to investigate the effect of transdermal administration of jojoba oil on blood biochemical parameters in mice, and the study raises the question of whether the fatty acids constituting the wax ester (jojoba oil) are percutaneously absorbed into the blood. Furthermore, confocal microscopic studies on the penetration of jojoba oil into human skin show that jojoba oil only penetrates the stratum corneum's outermost layers. More research is needed to determine which jojoba oil constituents can be absorbed transdermally.
