In which skincare products can we find squalane?

Squalane is the hydrogenated form of squalene, a lipid that makes up human sebum, a skin-protecting agent that contributes to the formation of the hydrolipidic film. The use of squalane is often preferred over squalene in skin and hair care because this chemical form is more stable (less susceptible to oxidation).

Squalane is perfectly assimilated by skin cells. Non-greasy and non-comedogenic, it does not clog pores and quickly penetrates the epidermis to soften its touch. This lipid contribution combats skin dryness and helps repair the skin's hydrolipidic film, enabling it to perform its primary function: preventing the body's water from evaporating. The skin remains hydrated for longer and the sensations of tightness characteristic of dry skin are reduced. Squalane also helps to prevent dehydration fine lines. Besides the skin, it can be applied to the hair as a heat protective treatment. Squalane makes the hair shiny and reduces split ends due to its moisturising properties.

Regarding its extraction method, squalane has long been a subject of controversy. Indeed, even today, it can still be extracted from shark livers for economic reasons. This is a real ecological disaster as plant-based alternatives have been available for several years: squalane can indeed be extracted from sugarcane, wheat germ, palm trees, and olives. At Typology, we only incorporate plant-based squalane in our skincare products; this comes from the unsaponifiable fraction of olive oil or sugarcane.

Squalane is a particularly versatile ingredient as it easily integrates into any oil phase in formulation. Thus, in skincare, it can be found in creams, scrubs, oily serums, massage oils, non-greasy dry body oils, body lotions, hand and foot creams. Regarding hair care, this emollient can be found in repairing serums, protective shampoos and conditioners, balms and masks. Moreover, it sometimes constitutes an element of the oily phases of makeup formulas such as foundations, lipsticks, eyeshadows, or even mascaras.

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.

• Thehydrating botanical blend with papyrus is a night serum that helps to restore skin hydration and promote cellular regeneration.

• Thetightening botanical blend with nopal is a night serum that helps to firm the skin through the toning and regenerating actions of 7 botanical extracts, including immortelle essential oil.

• The nourishing face cream formulated with hyaluronic acid and shea butter is a treatment enriched with lipid-replenishing and moisturising active ingredients to restore skin suppleness and reduce feelings of tightness.

• The nourishing serum squalane 100% is a treatment recommended for dry skin, with the aim of reducing feelings of tightness and diminishing dehydration fine lines.

• The tinted serums are enriched with vitamin C for a radiant complexion and aloe vera for skin hydration. They provide light coverage and even out the skin tone. Moreover, these 2-in-1 products exclude fragrance, nanoparticles, and silicones, which are often included in the formulation of traditional foundations and can promote the appearance of blemishes. Each tinted serum can match a wide spectrum of skin tones. The six shades of our serums have been developed according to the Fitzpatrick phototype scale.

With regards to the body, the following treatments contain plant-derived squalane:

• Therelipidating shower oil Vitamin E+F 2.5% + Bitter Almond Extract is an antioxidant treatment that restores suppleness to the epidermis and reduces feelings of tightness, while delicately scenting the skin with a light almond fragrance.

• The nourishing body cream restores the lipid barrier, reduces feelings of tightness and protects the skin from external aggressions.

• Therich hair oil with pequi and argan oil nourishes and restructures the hair fibre to protect it from heat. The hair becomes soft, shiny and manageable.
