Tout savoir sur le squalane

Everything you need to know about squalane.

Squalane is a plant-based lipid that is highly compatible with the skin. Indeed, it is derived from squalene, a molecule naturally present in sebum. Non-greasy, it quickly penetrates the epidermis and softens its touch. Let's focus on this increasingly renowned ingredient in skincare and haircare products.


What is squalane?

Squalane is a vegetable lipid derived from squalene, a substance naturally found in certain plants as well as in humans. Indeed, human sebum contains approximately 15% squalene.

The characterisation of squalene dates back to the beginning of the 20th century. Tsujimoto first isolated this molecule from theshark liver oil, hence the name he attributed to it.

Nevertheless, sharks are listed on the red list of endangered species and the European Union prohibits their capture. Therefore, nowadays, the squalane present in skincare products is of plant origin. It can be extracted from sugarcane, wheat germ, palm trees, as well as olives.

From a chemical perspective, squalane is a branched hydrocarbon with the raw formula C30H62. It is a hydrogenated version of squalene. Unlike squalene, squalane is a so-called saturated molecule: it does not contain a double bond and cannot be degraded by reacting with oxygen.

The benefits of squalane for the skin.

Squalane is a non-greasy oil with a dry touch that quickly penetrates the epidermis. It is often referred to as an active emollient. Not only does it soften the skin, but it also provides it with several benefits.

  • It prevents the epidermis from dehydration. Its biomimetic structure with sebum allows the repair of 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.

  • It stimulates cellular renewal enabling the refinement of skin texture and unclogging of pores, thus preventing the appearance of blemishes.

  • It reduces the appearance of fine lines and wrinkles and improves skin elasticity.

The benefits of squalane for hair.

When applied to hair, squalane provides a thermal protection and strengthens the hair. It also protects them from external aggressions by forming a soft film on the surface. Regarding the scalp, squalane strengthens the skin barrier thus fighting against dehydration, thereby preventing the onset of itching and dandruff.

Squalane, cosmetic indications.

Squalane is a dry oil non-comedogenic ; it is suitable for all skin types but remains particularlywell-suited to dry skin.

There are no contraindications to the cosmetic use of squalane, it can be used without risk by children as well as pregnant and/or breastfeeding women.

This vegetable oil is stable against oxidation. However, it is still best preserved when kept cool and out of direct light.

In which skincare products can one find squalane?

When applied topically, squalane is found in creams, scrubs, oily serums, massage oils, and non-greasy dry body oils. In terms of hair care, this emollient can be found in restorative serums, protective shampoos and conditioners, as well as balms and masks.

Typology has developed several galenic formulations containing this multifunctional ingredient. For the face, the following treatments are enriched with olive squalane:

  • The regenerating facial scrub gently exfoliates and unclogs pores. This gel transforms into an exfoliating oil under the effect of massage, then into a milk upon contact with water. Containing essential oils, it should not be used by pregnant women.
