Essential fatty acids.
The major part of emu oil is oleic acid (± 40%) which acts as a carrier to penetrate the active ingredients deeply into the skin layers. Besides that the unsaturated fatty acids contain an considerable amount of linoleic and alpha linoleic acid, the so-called essential fatty acids. These fatty acids are not being produced by the human body itself, but play an important role by the regeneration of new skin cells.
According to Dr. Leigh Hopkins, Pharm. D. in the US all cells produce hormones which are coming from these fatty acids. These hormones affect all aspects of the activities of a specific cell. They play a role in inflammations, the healing process and the dying of a cell. If you don’t consume sufficient of these “good” fatty acids, your body cannot work efficiently. The oil supplies through it’s essential fatty acids the need to have the cells function normal. If you see the skin as the largest cell wall there is, you can say that a dry, raw skin is a sign of a lack of essential fatty acids
Emu oil contains for more than 70% of unsaturated fatty acids, of which 20% essential fatty acids. The remarkable aspect of emu oil is the ratio between the saturated, unsaturated and essential fatty acids which matches closely the ratio of the fatty acids in the human skin.
