Introduction
SQL100 contains 100% plant-based squalane, which is a saturated form of squalene where the double bonds have been eliminated by hydrogenation. Thus, squalane is chemically less susceptible to oxidation than squalene. It is also a non-comedogenic moisturiser that is safe for sensitive skin.
Mechanism
Squalene is one of the most abundant lipids produced by human skin cells and is a component of human sebum (13%). It acts as a singlet oxygen receiver, protecting the skin surface from lipid peroxidation due to exposure to UV and other sources of ionising radiation.[1]
