Jojoba — a liquid wax which is commonly referred to as an oil. Jojoba's chemical composition is very close to sebum, a natural fluid produced by human skin and a natural protective barrier. It also aids in regulating moisture by reducing trans-epidermal water loss. It contains a significant amount of myristic acid, a fatty acid that is known to act as an anti-inflammatory. Jojoba contains some of the longest-chain fatty acids of any of the carriers and absorbs better than most other carriers. Studies indicate that jojoba oil can penetrate rapidly by absorption via the pores and hair follicles. From these areas, it seems to diffuse into the stratum corneum layer and acts with intercellular lipids to further reduce water loss. Jojoba is derived from plant seeds.
