Unsaponifiable Fraction of Olive Oil
The Unsaponifiable fraction of olive oil is a part of virgin olive oil (about 2%) that does not turn into soap as it is chemically composed of fatty molecules that do not react with a basic substance. It is a mix of chemical molecules such as sterols (beta-sitosterol, avenasterol, campesterol, stigmasterol), waxes, squalene which stimulates the production of collagen and elastin and it hydrates the skin very well. It also has photoprotective properties, protecting the skin exposed to UV rays and it helps to restore the epidermal barrier of dry or problematic skin (for instance with eczema or psoriasis).
