What is Squalane?
Squalane is a highly-refined botanical lipid with a molecular structure that is very similar to skin lipids. With a natural affinity to skin, this lightweight lipid absorbs easily without leaving a greasy residue. An effective emollient, Squalane has been traditionally used to help protect skin’s barrier and seal in moisture for softer, smoother skin.
Is Squalane good for your skin?
Not only is Squalane good for your skin–it is actually naturally present in skin. Found plentifully in your skin’s sebum until your early 20s, Squalane begins to deplete with age which can leave skin prone to rough and dry areas. Using lotions, serums and moisturizers with Squalane can help replenish skin for a soft, smooth and healthy appearance.
Squalane vs. Squalene
While they are definitely related, Squalane and Squalene are not identical. Squalane is actually the hydrogenated form of Squalene.
When Squalene was first discovered in skin (it makes up about 13% of skin’s sebum), it began to be explored for use in cosmetics and skincare. However, Squalene is highly unstable and prone to oxidation–meaning it will eventually darken, become viscous and emit an odor.
The first production of Squalane from Squalene was reported in 1916. With many similar benefits for skin, Squalane is stable against heat and oxidation making it ideal for skincare formulations. It also has an imperceptible odor, clear color and is highly compatible with skin.
Overall, the key differences between Squalene and Squalane are:Squalene
- Highly unstable
- Easily oxidizes
- Stable against heat and oxidation
- Imperceptible odor and clear color
