Perhydrosqualene and the Pescatarian Diet

Perhydrosqualene, also known as squalane, is a hydrogenated form of squalene, a natural lipid originally sourced from shark liver oil. It is a stable, saturated fat that is often used in the cosmetics and skincare industry for its moisturizing and emollient properties. Unlike squalene, perhydrosqualene is not susceptible to oxidation, making it a preferred ingredient in formulations that require a long shelf life and stability.
