How to use squalane?

The squalane is the hydrogenated form of squalene, a lipid naturally present in the skin secreted by the sebaceous glands. Squalene is not stable to oxidation due to its double bonds on its carbon chain. Squalane is preferred in cosmetic formulas because of its longer shelf life.

The use of this active emollient in the beauty industry has long been controversial due to its origin: squalene can be extracted in large quantities from shark liver oil. However, with the increasing regulation of fishing for these threatened species, most companies today use plant-derived squalane, most often sourced from olives or sugarcane.

At Typology, we only incorporate plant-derived squalane into our skincare products.

Squalane is often referred to as anactive emollient. Not only does it soften the skin, but it also prevents the epidermis from dehydration. Its biomimetic structure with sebum allows it to repair the hydrolipidic film, thereby strengthening the skin's barrier function and preventing the body's water from evaporating. The skin remains hydrated for a longer period and the feelings of tightness common to dry skin are reduced.

Furthermore, squalene is a major component of sebum, comprising about 15% of its content. However, its natural production by skin cells tends to decrease around the age of 30. This decline contributes to increased dehydration and the skin shows more "signs" of aging. Therefore, a daily intake of squalane helps combat this inevitable loss and slows down the skin dehydration process that intensifies over the years.

Due to its moisturizing and softening properties, this oil is suitable for all skin types but is particularly recommended fordry skin. It is applied directly with the fingers at the end of your routine, on clean and dry skin, using circular motions to ensure its absorption. Squalane can be used every day, evening and morning. Indeed, even though it is an oil, it has a dry touch and quickly penetrates the skin, leaving no greasy residue. Therefore, it is possible to apply your makeup products and sun protection afterwards.
