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 now 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 longer and the feelings of tightness characteristic of dry skin are reduced.

Furthermore, squalene is a major component of sebum, comprising approximately 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 becomes more "marked". Therefore, a daily intake of squalane helps to combat this inevitable loss and slows down the skin dehydration process that intensifies over the years.

Due to its moisturising and softening virtues, 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 the routine, on clean and dry skin, making circular movements to enhance its penetration. Squalane can be used every day, in the evening as well as in the morning. Indeed, even though it is an oil, its texture is dry and it quickly penetrates the skin, leaving no greasy residue. Therefore, it is possible to apply one's makeup products and sun protection afterwards.
