Emu oil is one of those ingredients that those looking for anti-inflammatory effects in their products may seek.
Emu oil is high in fats, particularly long chained triglyceride esters, such as Oleic acid and Linoleic acid. It also contains saturated fatty acids like palmitic acid. It is thought to derive its anti inflammatory and antioxidant effects from its carotenoids and tocoferols.
It has been used in wound healing and and the relief of minor arthritis or pain. There are some studies evaluating its benefits in the context of managing burns and other wounds. The results of these studies may show some modest benefit with little adverse reaction seen.
I would not think of this as an everyday skin care ingredient to seek, necessarily, however it may be of some slight benefit in the context of healing although I have not seen any studies evaluating it compared to other wound care options.
