AYour skin's natural sebum is made up of several ingredients including: Triglyceride Oils (Fatty Acids of rather defined amounts: 2% Myristic Acid, 20% Palmitic Acid, 4% Palmitoleic Acid, 11% Stearic Acid, 31% Oleic Acid, 5% Linoleic [Omega 6] Acid, and less than 1% Linolenic [Omega 9] and other fatty acids), Wax Esters, Cholesterol Wax Esters, Squalene, some phytosterols and ceramides. But the major components are Fatty Acids, Wax Esters and Squalene.

Now, Jojoba Oil is the ONLY source on earth of botanical wax esters. And these wax esters have the same composition as skin wax esters. Emu Oil does have a fatty acid composition similar to that of humans, essentially because it is a living creature. But, there are also more polyunsaturated fatty acids in Emu oil which means one thing... it is an inherently unstable oil. It will oxidize, rather quickly into short chain aldehydes and ketones and these molecules smell bad. That is the definition of becoming "rancid". There is just no way that I would formulate with, or put, animal fat on my skin. The FAR better choice is Macadamia oil which has a fatty acid profile extremely close to that of human sebum, and it is an inherently stable oil. It does not go rancid.

So, look for cosmetic products that combine jojoba oil, macadamia oil, squalene, and other inherently stable oils and you will have found a very "skin friendly" cosmetic product that not only will function very well as a moisturizer, but will not disrupt normal skin function like most other creams and lotions on the market today. This is scientific fact, and it is backed up by a study from the University of Sweden that was published last fall.
