How is jojoba oil used?

Jojoba is a tree native to the Mexican deserts, cultivated solely for its oil. At room temperature, jojoba oil is a viscous yellow liquid with a nutty aroma. When cold-pressed, it retains all the active ingredients of the plant. Like most vegetable oils, its composition primarily contains essential fatty acids such as thegadoleic acid, an omega-9.

The biochemical composition of jojoba oil is remarkably similar to that of human sebum, making it highly tolerable and effective in regulating the phenomena ofhyperseborrhea. As such, it purifies skin and hair prone to oiliness. Moreover, it strengthens the hydrolipidic film, the skin's protective layer against external aggressions. By forming an impermeable barrier, the hydrolipidic film prevents the proliferation of harmful bacteria that can cause inflammation. It also maintains the skin's natural hydration, necessary to ensure its suppleness and softness. Like the skin, hair needs a protective layer to prevent dehydration, which leads to split ends and breakage. Therefore, jojoba oil is also used to care for dry and dehydrated hair.

Furthermore, due to the presence of unsaponifiables, namely vitamins and minerals, jojoba oil also acts as a restorative agent. The action of vitamin E and zinc, in particular, helps to combat oxidation reactions by trapping free radicals. As a reminder, these free radicals are responsible for the degradation of certain skin constituents such as collagen and elastin, causing premature ageing. This results in skin sagging and the appearance of wrinkles. Jojoba oil thus helps to prevent skin ageing.
