Squalane is a stable, colorless, and odorless oil derived from plant sources like olives, sugarcane, and amaranth seeds, or from shark liver oil. It is a hydrogenated version of squalene, a natural component of human sebum (skin oil). Squalane is highly moisturizing, non-comedogenic, and easily absorbed by the skin.In cosmetic formulations, squalane is used for its emollient and moisturizing properties. It helps to improve skin hydration, smoothness, and elasticity, making it suitable for various skin types, including sensitive and acne-prone skin. Squalane can be found in a wide range of products, such as facial serums, creams, lotions, and even makeup products, where it helps to create a smooth and silky texture. Additionally, squalane has antioxidant properties that can protect the skin from environmental stressors and promote a healthy skin barrier.
