Squalane and Squalene in skin care. Same thing? Or not? Yes and No.

Both are a natural component of human sebum. Sebum is the natural oil found in your own skin. Both are also found in rice bran, wheat germ, olive oil and yuck, shark liver (what do you want to put on your skin, hmm?).

Squalene is often derived from sharks for cosmetic use. Particularly in Japanese products.  Squalane is derived from squalene.  Both do exactly the same thing on and in your skin. So other than the fact that you may not want to use oil derived from a shark, why choose squalane derived from plant sources?

Still reading? Guess you do want to know…

Squalene is highly unstable as a cosmetic ingredient. No matter what it is derived from. Shark, rice bran, olive oil, etc. This is because it is a double bond molecule.  Meaning a very short shelf life and quick to oxidize or spoil. Squalane is not a double bond molecule, so it is much more stable as a cosmetic ingredient. Squalane has a shelf life of over 2 years and does not oxidize quickly with exposure to air. That’s all I’m saying on that. It’s boring and I am not going there. I want to talk skin care.

So, squalane is a derivative of squalene. Squalane has all the great qualities of squalene. And when derived from olive oil is environment and animal friendly. I absolutely prefer to put something on my face that is plant derived rather than animal. How about you?

Since plant derived squalane is so similar to the natural squalane in our own skins sebum, our bodies “identify” it as being “our own”.  Our naturally occurring moisture. Squalane is also responsible for the synthesis of cholesterol, steroids and vitamin D. And since it is a derivative it is more saturated with the good stuff we want, leaving behind components that we don’t need.

Did you know that squalane as a natural oil lipid composes up to 15% of skin fats in the teenage years? Once we enter our 20’s it begins to decline. This can mean pre-mature aging in your 30’s and 40’s. Read the rest of this entry »
