Vegetable squalane, a stable derivative of squalene naturally present in our sebum, has established itself as an essential ingredient in cosmetics. This colorless and odorless sensory oil penetrates quickly into the skin with a surprisingly dry feel, making it a valuable ally for our daily beauty routine.
We particularly appreciate the many benefits of squalane for the skin. Indeed, this branched hydrocarbon with formula C30H62 effectively helps reduce skin moisture loss while offering emollient, repairing and softening properties. Its plant origin, mainly derived from olive oil, but also from almond, avocado or sugar cane oil, makes it an ecological and ethical alternative.
In this article, we'll explore together what exactly plant squalane is, its multiple benefits for different skin types, and how to effectively integrate it into your beauty routine. We will also share some homemade recipes to take full advantage of its exceptional properties.
What is vegetable squalane?
You may have already noticed this ingredient on the labels of your favorite cosmetics, but do you really know what plant-based squalane is? This active ingredient with multiple virtues deserves a closer look to understand why it has become so popular in the beauty industry.
Natural origin: olive, sugar cane, amaranth
Plant squalane is obtained by hydrogenation of squalene, a molecule naturally present in several plant sources. Contrary to what many think, there are various origins for this precious oil:
- Olive oil : the most common source, particularly rich in squalene (up to 0.7% of its composition)
- Sugar cane : thanks to biotechnological advances, squalane is now extracted by fermentation of sugar cane
- Amaranth : this South American plant contains an interesting concentration of squalene
- Rice bran oil : a lesser known but effective alternative
Other sources such as wheat germ oil, avocado and almonds complete this plant panorama. Each raw material offers squalane with slightly different, although fundamentally similar, properties.
Difference between squalene and squalane
It is essential to distinguish these two often confused compounds. Squalene (with an "è") is a lipid naturally present in our sebum - approximately 13% of its composition. However, this molecule has a major drawback: it oxidizes easily on contact with air.
To overcome this problem, the cosmetic industry transforms squalene into squalane (with an "a") through a hydrogenation process. This chemical transformation stabilizes the molecule, making it:
- More resistant to oxidation
- More durable over time
- Lighter on the skin
- Less comedogenic
Squalane retains all the qualities of the original squalene while eliminating its defects, which explains its growing popularity.
Why choose plant origin
In the past, the squalane used in cosmetics mainly came from shark liver, which is extremely rich in squalene. However, this practice posed significant ethical and environmental problems. Today, vegetable squalane stands out as a responsible alternative for several reasons:
First, its use preserves shark populations, some species of which are threatened with extinction. Secondly, plant extraction processes prove to be more sustainable and less polluting. Finally, plant-based squalane generally has fewer impurities and a more stable profile.
The evolution of extraction technologies now makes it possible to obtain a vegetable squalane of equal or even higher quality than that of animal origin, with the additional advantage of being compatible with vegan and cruelty-free cosmetics.
The benefits of squalane for the skin
The multiple virtues of vegetable squalane make it a popular active ingredient in the world of modern cosmetics. Let's find out together why this ingredient is becoming essential in our skin care formulations.
Deep hydration without greasy effect
Vegetable squalane excels in its ability to intensely hydrate the skin without leaving a greasy film. Unlike other heavier oils, it penetrates quickly and forms a thin, breathable protective layer that maintains moisture balance. This lightweight oil effectively prevents transepidermal water loss while providing a dry, silky sensation much appreciated in contemporary skincare.
Strengthening the skin barrier
Squalane acts as a caring guardian for our skin. It considerably strengthens the barrier function of the epidermis, a crucial element for healthy skin. By integrating perfectly with epidermal lipids, it fills the spaces between skin cells, thus improving the integrity of this barrier over time. This protective action particularly helps sensitive or weakened skin.
Softening and softening effect
Thanks to its remarkable emollient properties, squalane visibly softens and softens the epidermis from the first application. It improves skin elasticity and provides immediate comfort, particularly to dry skin or dehydrated. In addition, it helps to reduce fine lines and maintain the natural suppleness of the skin.
Protection against external attacks
Plant squalane has antioxidant properties that help protect skin from oxidative stress and UV damage. It forms a protective barrier against pollutants and other environmental aggressions without blocking pores. In addition, its anti-inflammatory effects soothe redness and inflammation, thus relieving skin discomfort.
Biomimetic affinity with human sebum
The major advantage of squalane lies in its structural similarity to our natural lipids. This biomimetic affinity explains its exceptional tolerance by all skin types. Thus, it naturally regulates sebum production without clogging pores, which makes it particularly suitable for combination to oily skin. This remarkable compatibility makes it a universal active ingredient appreciated in dermocosmetics.
How to use vegetable squalane in your beauty routine
Plant squalane fits perfectly into almost every step of our daily beauty routine. Its exceptional versatility makes it a valuable ally for the face, body, hair and even makeup.
Facial serums and treatment oils
To maximize the benefits of squalane on the face, respect the order in which the products are applied. After cleansing and possible exfoliation, apply your water-based serums (like hyaluronic acid) first, then any formulas containing squalane. The latter acts effectively as a protective barrier to prevent moisture from escaping. It can also be used before applying retinol to reduce potential irritation, thanks to its natural anti-inflammatory properties.
Body creams and milks
On the body, vegetable squalane provides hydration and suppleness without feeling greasy. Integrate it into your routine by applying it after showering to slightly damp skin to lock in moisture. Particularly beneficial for dry areas such as elbows, knees and feet, it can also be used as a light massage oil offering a sensory glide without a residual film.
SOSKIN densifying cream
The premium anti-aging treatment smoothes, nourishes and plumps the skin in 4 weeks thanks to biocompatible squalane and native collagen fibers which reactivate skin protection and help the skin regain its balance, while shea butter and apricot kernel oil, with lipid-replenishing properties, provide elasticity and comfort.
Hair care: dry ends, curly hair
For hair, squalane forms a light protective film around the hair fiber. On dry ends, a few drops are enough to add shine and suppleness without weighing it down. Curly and frizzy hair will particularly appreciate its disciplining and moisturizing properties. You can use it as a pre-shampoo treatment (15-30 minutes before washing) or as a leave-in treatment on damp or dry hair.
Makeup: foundation, mascara, gloss
In makeup, squalane provides comfort and hold. Foundations including it offer a natural, luminous finish that does not cling to dry areas. Some mascaras enriched with squalane nourish the eyelashes while applying makeup. For lips, squalane glosses provide up to 12 hours of intense hydration without stickiness.
Recommended dosage according to use
The dosage varies depending on the application: for the face, 2-3 drops are enough for optimal hydration. On hair, start with small amounts (1-2 drops) to avoid greasy effect, gradually increasing if necessary. For body care, the amount depends on the area to be treated - a few drops for targeted areas, up to a teaspoon for a full massage.
