Dayse# but comedogenic=1/5, it cause acne
For me this ingredient was very comedogenic. I used it once and the next morning i had a big under the skin painful pimple.
I put Timeless Squalane on my 8 y/o son's cheek because he had a dry patch and the next morning he woke up with a deep pimple. I also broke out with several pimples on my cheeks after using Timeless Squalane, but I thought maybe it was something else in my skin care routine. After what happened to my son, I am sure it was the Squalane.
Squalane is a hydrocarbon derived by hydrogenation of squalene.
In contrast to squalene, due to the complete saturation of squalane, it is not subject to auto-oxidation.
This fact, coupled with lower costs associated with squalane, make it desirable in cosmetics manufacturing, where it is used as an emollient and moisturizer.
The hydrogenation of squalene to produce squalane was first reported in 1916.
