Ingredient Spotlight: Squalene

  • February 22, 2019

Squalene, to me, represents the perfect natural alternative to the most common ingredient in skincare, “paraffinun liquidum”which is from a chemical point of view a hydrocarbon, same as the squalene, which comes in liquid form due to its unique structure. I use the stable version which is called squalane.

I made it one of the twelve key ingredients because it protects the skin, thanks to the ability to regenerate the lipid film which prevents aggression by external agents. It is also moisturising because it reduces the evaporation of water from the deeper epidermal layers (Trans Epidermal Water Loss) which I mentioned in previous posts. It is all about the TEWL.

Over the years the sebum production of the skin is reduced, this is why, more mature skin usually feels drier. So it is a great addition to your regime in order to avoid dryness and also to provide elasticity.

Squalene is found in the unsaponifiable fraction of various oils (the most precious part of the vegetable oils and butters too) and represents an important content, mainly in olive, rice and pumpkin oil. Once again, quality and the extraction method is paramount, in fact there are studies that show huge differences in the amount of squalene from various suppliers of olive oil. In my opinion is better to choose unrefined versions, as they tend to use alkaline substances when the industry processes oils, which greatly reduces the content.

Just to get a bit skincare geek, below, there is a table where it shows the content of squalene in different oils,so you can get a better idea and make your own choices.
