Properties and benefits of squalane

Definition of Squalane

Squalane is a saturated and stable lipid derived from squalene, a substance naturally present in human skin. Once extracted from shark liver oil, the squalane used in cosmetics today is mainly plant-based, obtained from oils such as olive oil or sugar cane oil. Odourless and non-comedogenic, squalane is prized for its moisturising and protective properties, blending perfectly into skincare formulations.

Actions and Benefits of Squalane

Property of Squalane: Deep Hydration

Squalane acts as an emollient, softening and smoothing the skin by mimicking the natural lipids of the epidermis. It penetrates quickly to provide intense hydration without leaving a greasy film, helping to restore the lipid barrier, which is essential for dry and sensitive skin.

Squalane Properties: Protection and Anti-Ageing

In addition to its moisturising power, squalane protects the skin from environmental aggressors and free radicals thanks to its antioxidant properties. It helps prevent the signs of ageing, such as wrinkles and loss of elasticity, by keeping the skin smooth and radiant.

Squalane Properties: Lightweight and Non-Comedogenic

Thanks to its lightweight texture, squalane does not clog pores and is suitable for all skin types, including oily or acne-prone skin. It helps balance sebum production, making the skin more harmonious and less prone to imperfections.

Clinical and Scientific Studies on Squalane

A study entitled ‘Squalene – Background and Perspectives in Cosmeceuticals Formulas’ highlighted the multiple roles of squalane in skin care. This study demonstrated that squalane restores the lipid balance on the skin's surface, prevents trans-epidermal water loss, and protects against oxidative damage. Additionally, it acts as a carrier for other active substances, facilitating their penetration into the deeper layers of the skin, making it a versatile and essential ingredient in cosmetic formulations.

Squalane sourcing

Today, squalane is mainly plant-based, sustainably extracted from sources such as olive oil or sugar cane. These environmentally friendly production methods guarantee high-quality, pure and stable squalane, while protecting marine ecosystems that were once threatened by the extraction of squalane from sharks.

Fun facts about squalane

Squalane takes its name from the Latin squalus, meaning shark, in reference to its historical extraction. With advances in biotechnology, squalane is now mainly plant-based, making this ingredient more ethical and accessible while maintaining its exceptional properties.
