What is squalane? Mechanism of action simply explained
Squalane is a derivative of squalene, a lipid molecule naturally produced by our body. Our skin spontaneously produces it until our thirties, then production gradually decreases with age—hence the appearance of the first signs of dryness and skin thinning. Cosmetic squalane is obtained by hydrogenating plant-based squalene, mainly from sugarcane or olive oil. This stabilization step makes it non-oxidizable and perfectly stable, unlike raw squalene which quickly goes rancid.
On a molecular level, squalane is a branched-chain saturated hydrocarbon that perfectly mimics the structure of natural skin lipids. It integrates into the epidermal lipid bilayer like a "key in a lock," strengthening the skin barrier and limiting transepidermal water loss (TEWL). Its light molecular weight allows it to penetrate the superficial layers of the epidermis without leaving a greasy film, unlike conventional vegetable oils.
💡 Common misconception
"Squalane is a greasy oil only suitable for dry skin." False! Its ultra-light texture and structure similar to natural sebum make it ideal for combination and even oily skin. By regulating sebum production through feedback, it can paradoxically help mattify excessively shiny skin—because well-hydrated skin produces less compensatory sebum.
The proven benefits of squalane for your skin
Squalane is not an active ingredient of promises: its benefits are documented by numerous clinical studies in dermatology. Here's what it actually does:
Deep and lasting hydration: By reconstituting the hydrolipidic film, squalane acts as a hydration lock. It measurably reduces transepidermal water loss from the first applications. Skin regains a smooth, supple, and comfortable appearance even in aggressive environments (air conditioning, cold, pollution).
Gentle and progressive anti-aging action: By filling the intercellular spaces of the stratum corneum, squalane reduces the appearance of dehydration fine lines and gives the skin an immediate visual bounce. In the long term, it supports natural cell repair mechanisms by maintaining an optimal lipid environment for keratinocytes.
Antioxidant properties: Squalane partially neutralizes free radicals resulting from oxidative stress (pollution, UV, tobacco). It protects cell membranes from lipid oxidation, a mechanism directly involved in premature skin aging.
Soothing and calming effect: Thanks to its perfect skin tolerance, squalane reduces mild inflammation, redness, and feelings of discomfort. It is one of the few active ingredients recommended after aggressive procedures such as chemical peels, laser hair removal, or dermabrasion.
Texture improvement: Regular use visibly smooths the skin texture, reduces the "orange peel" appearance, and gives a "silky skin" effect that is visible and palpable.
🔬 Expert tip
Squalane is one of the few cosmetic active ingredients that works synergistically with almost all other ingredients. It potentiates the action of moisturizing active ingredients like hyaluronic acid (by sealing water into the epidermis after application), improves the penetration of anti-aging active ingredients like peptides, and stabilizes formulas containing vitamin C. In the Lili Margo Floractiv20+® range, plant-based squalane plays precisely this role as a carrier and lipid shield for the 20 patented floral extracts.

What squalane does NOT do: separating fact from fiction
Squalane's popularity has led to its share of confusion. It's important to frame its limitations to avoid disappointment and misuse:
It does not replace sunscreen. Although it has slight antioxidant properties, squalane offers no measurable UV protection. If your morning routine includes squalane, always apply an SPF 30 minimum over it, especially during summer.
It does not exfoliate the skin. Unlike glycolic acid or salicylic acid, squalane does not stimulate cell renewal. If you need deep smoothing or spot correction, combine it with a gentle chemical exfoliant—it will also be excellent for soothing post-exfoliation irritation.
It does not fill deep wrinkles. Squalane acts on superficial fine lines related to dehydration, but it does not replace the action of fillers or signaling peptides for deep expression wrinkles. Use it in combination with firming and plumping active ingredients for optimal results.
It does not treat inflammatory acne. If infected blackheads or red pimples are present, squalane is not a treatment. However, its soothing effect can reduce peri-lesional redness without aggravating inflammation.

📌 To remember
Squalane is a universal, stable, and ultra-tolerated active ingredient that restores the skin's natural lipid film, limits water loss, and potentiates the effectiveness of other active ingredients in your routine. It is suitable for all skin types, morning and evening, and integrates into all steps of a well-constructed anti-aging treatment. At Lili Margo, it acts as a carrier for the 20 Floractiv20+® floral extracts for optimized effectiveness.
Squalane and skin types: who can use it?
🌵
Dry skin
Intense lipid action. Restores depleted hydrolipidic film and reduces tightness. Use morning and evening as a final layer.
✨
Combination to oily skin
Ultra-light and non-comedogenic texture. Regulates compensatory sebum. Ideal for a light finish in the morning.
🌸
Sensitive skin
Perfect tolerance and soothing effect. Reduces redness and discomfort. One of the only active ingredients recommended after peeling or laser.
⏳
Mature skin
Compensates for the natural decrease in squalene produced by the skin after 30 years old. Plumps fine lines and restores radiance to dull complexions.
How to integrate squalane into your routine in 4 steps
Squalane is one of the easiest active ingredients to incorporate into a beauty routine because it adapts to almost all formulations and positions in the application order. Here is the optimal method:
Step 1 — Cleansing: Always start with a perfectly cleansed and makeup-free face. Squalane penetrates better on skin free of excess sebum, makeup residue, and pollution particles. Opt for a gentle, non-stripping cleanser.
Step 2 — Toner and active serum: Apply your toner, then your concentrated serum (hyaluronic acid, peptides, vitamin C depending on your routine). Squalane will then seal these active ingredients into the epidermis.
Step 3 — Application of pure or formulated squalane: If you are using pure squalane, place 2 to 3 drops on your fingertips and warm them slightly before pressing onto your cheeks, forehead, chin, and around the eyes. Use light upward circular motions. If your serum or cream already contains squalane (like Lili Margo's Floractiv20+® Capsule Serum), this step is integrated—no need for an additional layer.
Step 4 — Day or night cream: Finish your routine with your usual moisturizer. In the morning, don't forget your minimum SPF 30 sunscreen. In the evening, allow your skin time to benefit from squalane's nightly repairing action.
FAQ — Your questions about squalane
Is squalane suitable for oily skin?
Yes, squalane is non-comedogenic and its ultra-light texture does not clog pores. It can even reduce excessive sebum production by rebalancing the skin's lipid film. Combination to oily skin types can use it in moderate amounts, preferably in the morning before makeup.
What is the difference between squalane and squalene?
Squalene is a molecule naturally produced by the skin and found in certain vegetable oils (olive, amaranth). Squalane is its hydrogenated and stabilized version, used in cosmetics. Squalane does not go rancid, is more stable to oxidation, and is better tolerated by the skin than raw squalene.
Can squalane be used every day?
Absolutely. Squalane is designed for daily use, morning and evening, on the face and body. Its exceptional skin tolerance makes it suitable for regular use without risk of habituation or irritation, even for reactive skin.
Can squalane replace my moisturizer?
Squalane complements a routine but does not entirely replace a formulated moisturizer. A cream usually contains humectants (glycerin, hyaluronic acid) that draw water into the deeper layers, whereas squalane primarily seals hydration on the surface. The two are complementary for complete hydration.
How does Lili Margo integrate squalane into its Floractiv20+® technology?
At Lili Margo, plant-based squalane (from sugarcane) is used as a lipid carrier for the 20 patented floral extracts of Floractiv20+® technology. It facilitates the penetration of floral active ingredients into the epidermis, strengthens the skin barrier, and amplifies the 15 anti-aging factors of the formula. Its naturality perfectly aligns with the requirement of over 95% natural ingredients and the brand's Ecocert certification.
