Review

Full Review

There's a quiet elegance to a product that contains exactly one ingredient. No stabilizers, no emulsifiers, no fragrance, no preservatives — just squalane derived from sugarcane, bottled in Toronto, and sold for a price that borders on charitable. The Ordinary's 100% Plant-Derived Squalane is the kind of product that makes skincare feel refreshingly straightforward.

The science behind squalane starts with your own body. Squalene — the unsaturated precursor — is one of the most abundant lipids in human sebum, constituting roughly 12% of the oily mixture that keeps your skin supple, protected, and functioning as a proper barrier. The problem is that squalene production peaks in your teens and twenties, then declines steadily. By your thirties, the drop is noticeable. By your forties, it's significant. Topical squalane is essentially replenishment therapy — putting back what biology is taking away.

The plant-derived part matters more than you might think. Traditional squalane was sourced from shark liver oil, which is both ethically problematic and increasingly regulated. This product uses squalane derived from sugarcane fermentation, which produces a cleaner, higher-purity molecule. But the sourcing distinction goes beyond ethics: sugarcane-derived squalane contains fewer trace fatty acid impurities than olive-derived alternatives, which makes it safe for those prone to fungal acne — a distinction that olive-sourced squalane products can't always claim.

On the skin, this oil feels almost like nothing. Where the argan oil in The Ordinary's lineup has weight and presence, squalane is ghostly in its lightness. A few drops spread across the face and absorb within a minute or two, leaving behind a subtle healthy sheen rather than an oily film. There's no scent whatsoever — not even the faint botanical notes you'd find in most plant oils. It's skincare stripped to its most functional essence.

The mechanism of action is elegantly simple. Squalane functions primarily as an emollient and lightweight occlusive. It fills the gaps between corneocytes in the stratum corneum, smoothing the skin's surface and reducing the microscopic cracks through which moisture escapes. A clinical study on a squalane-containing serum documented statistically significant TEWL reductions of 2.61, 3.39, and 3.76 g/h/m² at 7, 14, and 28 days respectively — meaning the barrier gets progressively stronger with consistent use.

More recent research has revealed that squalane isn't merely passive. A 2025 study published in Molecules found that squalane counteracted UVA-induced inhibition of collagen biosynthesis in human dermal fibroblasts and demonstrated anti-inflammatory activity by reducing NF-kB and COX-2 expression. This suggests squalane isn't just locking moisture in — it's actively supporting the skin's repair mechanisms when under environmental assault.

The versatility of this product is one of its strongest selling points. It works beautifully as a final step over hydrating serums, locking in the water that hyaluronic acid draws to the skin's surface. It buffers the dryness and irritation that retinoids can cause without interfering with their activity. It can be mixed into foundation for a more luminous application. It works on dry cuticles, cracked lips, and frizzy hair ends. The fact that it's odorless and non-reactive makes it compatible with essentially every other product in your routine.

But — and this is an important but — squalane is not a moisturizer in the way most people understand the word. It doesn't add water to the skin. It prevents water from leaving. If you apply squalane to dry, dehydrated skin without any hydrating product underneath, you'll seal in the dryness and wonder what all the fuss was about. The key to getting this product right is layering: humectant first (hyaluronic acid, glycerin-based serum), then squalane to trap it. Get this order right and the results are genuinely impressive. Get it wrong and you'll dismiss it as overrated.

The packaging is standard Ordinary — functional, minimal, and decidedly unglamorous. The amber glass protects the oil from light, though squalane is considerably more photo-stable than its unsaturated precursor squalene. The dropper dispenses a reasonable amount per squeeze, though it can be slightly messy on the bottle neck after repeated use.

At $10.40 for 30 mL, the pricing follows The Ordinary's disruptive philosophy. Comparable plant-derived squalane oils from premium brands cost $25-40 for the same volume and the same single ingredient. The ECOCERT approval and USDA Bio-based certification provide third-party quality verification that most competitors at this price point don't offer.

The six-month PAO is worth noting — shorter than many skincare products, though squalane's hydrogenated structure makes it inherently more stable than unsaturated oils. Wiping the dropper neck clean after each use helps prevent the slight gumminess that some users report over time.

This isn't a product that announces itself. It doesn't tingle, glow, foam, or transform on contact. It doesn't photograph well for social media. It is, in the most literal sense, the oil your skin already makes, delivered from a sugarcane plant instead of your own sebaceous glands. For the many people whose skin has started producing less of it than it needs, that quiet biological relevance is exactly the point.

Ingredient	Function	Evidence
Squalane (Plant-Derived) (100%)	The sole ingredient in this formula, this sugarcane-derived squalane mimics the squalene that constitutes approximately 12% of human sebum. As a fully hydrogenated form, it's oxidatively stable and won't turn rancid like its precursor squalene, while retaining the same skin-identical emolliency and lightweight barrier-reinforcing properties.	Established mechanism for Dryness · established mechanism
Squalane (Barrier Support) (100%)	Functions as a lightweight occlusive that reduces transepidermal water loss without the heavy, greasy feel of petrolatum or mineral oil. Because this is 100% squalane with no emulsifiers or diluents, the barrier-reinforcing effect is maximized — clinical studies have documented TEWL reductions within the first week of daily use.

Evidence

Science & Expert Perspective

The Science

Squalane's biological relevance is well established. Human sebum contains approximately 12% squalene, its unsaturated precursor, making exogenous squalane one of the most skin-compatible lipids available in topical skincare. The hydrogenation that converts squalene to squalane eliminates the double bonds that make squalene susceptible to oxidation, producing a shelf-stable molecule with identical emollient properties.

A comprehensive review by Huang et al., published in Molecules (2009), documented squalene and squalane's roles as efficient singlet oxygen quenchers and lipid peroxidation inhibitors. The review noted that squalene constitutes a significant portion of the skin surface lipid film and plays a critical role in protecting deeper skin layers from UV-induced oxidative damage.

More recent research has expanded understanding of squalane's active properties. A 2025 study published in Molecules by investigators studying human dermal fibroblasts found that squalane at concentrations as low as 0.005-0.015% counteracted UVA-induced inhibition of collagen biosynthesis. The same study demonstrated that squalane stimulated fibroblast migration — relevant to wound healing — and showed anti-inflammatory activity by counteracting UVA-induced NF-kB and COX-2 expression. These findings suggest squalane is not merely a passive occlusive but actively participates in skin repair pathways.

Clinical data on barrier function supports the TEWL-reducing properties. A paper published in CosmoDerma (2023) documented statistically significant TEWL reductions at 7, 14, and 28 days of daily squalane serum use, with progressive improvement over time — indicating cumulative barrier strengthening rather than a purely surface-level effect. The Cosmetic Ingredient Review (CIR) expert panel has reviewed squalane's safety profile and concluded it is safe for use in cosmetic products at current concentrations.

Dermatologist Perspective

Dermatologists frequently recommend squalane as one of the safest and most universally tolerated facial oils available. Dermatology professionals often emphasize that its skin-identical structure — mimicking the squalene naturally present in human sebum — gives it an exceptionally low risk of irritation or allergic reaction. It is commonly suggested for patients with compromised barriers, post-procedure skin, or those experiencing irritation from retinoids and other active treatments. Dermatologists also highlight that sugarcane-derived squalane, as used in this product, is the preferred source for patients prone to Malassezia folliculitis (fungal acne), as it avoids the trace fatty acid impurities that can be present in olive-derived alternatives.

Guidance

Usage & Recommendations

How to Use

Apply 2-3 drops to clean skin as the final step of your skincare routine. For best results, layer over a hydrating serum (hyaluronic acid or glycerin-based) to seal in moisture — squalane is an occlusive, not a humectant, so it locks in hydration rather than providing it. Can be used morning and evening. In the AM, allow a minute to absorb before applying sunscreen. Can also be mixed into moisturizer or foundation, or applied directly to dry cuticles, lips, and hair ends. Wipe the dropper neck clean after each use to prevent gumminess.

Value Assessment

At $10.40 for 30 mL of ECOCERT-approved, USDA Certified Bio-based squalane, this is among the most affordable pure squalane oils on the market from a reputable brand. Comparable products from premium skincare lines cost $25-40 for the same volume and identical ingredient. Only one size is available, so there's no bulk discount option, but the base price is already low enough that this feels like a non-issue. The Ordinary's established brand credibility and third-party certifications provide reassurance that the low price reflects efficient business practices rather than compromised ingredient quality.

Who Should Buy

Anyone looking for a lightweight, universally compatible facial oil to seal in hydration and buffer active treatments. Particularly valuable for those with fungal-acne-prone skin who can't use most plant oils, post-procedure skin needing gentle barrier support, and retinoid users experiencing dryness and irritation.

Who Should Skip

Those who want a standalone moisturizer — squalane won't hydrate dry skin without a humectant underneath. Users who prefer completely matte finishes may find even small amounts too dewy. If you're looking for active anti-aging or brightening benefits, a multi-active serum will serve you better than this single-ingredient oil.

Background

The Story Behind This Product

Squalane was one of the earliest products in The Ordinary's lineup, reflecting the brand's philosophy that effective skincare doesn't need complex formulations or luxury pricing. Human skin naturally produces squalene (the unsaturated precursor), but production declines significantly after age 30 — this product replenishes that loss with a stable, plant-derived alternative sourced from sugarcane fermentation.

About The Ordinary Established Brand (5–20 years)

The Ordinary launched in 2016 under DECIEM and rapidly became one of the most recognized clinical skincare brands globally. Its ingredient-first, transparency-driven approach is backed by formulation science, though the brand does not conduct proprietary clinical trials on most products.

Myth vs. Reality

Common Myths

Myth

Squalane and squalene are the same thing.

Reality

Squalene (with an 'e') is the unsaturated form naturally produced by human sebaceous glands but is oxidatively unstable. This product contains squalane (with an 'a'), the fully hydrogenated, shelf-stable version that provides the same emollient benefits without the risk of oxidation or rancidity.

Myth

Facial oils like squalane will clog pores and cause breakouts.

Reality

Squalane has a comedogenicity rating of 1 (very low) and an irritancy rating of 0. Its molecular structure closely mimics the skin's own lipids, which means it integrates into the stratum corneum rather than sitting on top and blocking pores. This particular formulation is also fungal acne safe.

FAQ

Frequently Asked Questions

Is The Ordinary Squalane good for oily skin?

Yes, in small amounts. Squalane is lightweight and non-comedogenic with a comedogenicity rating of 1. Its molecular structure mimics human sebum, so oily skin types can use 1-2 drops as a final PM step without the heavy feel of traditional face oils. Reduce the amount or skip it entirely if your skin feels sufficiently moisturized.

Is The Ordinary Squalane safe for fungal acne?

Yes. This squalane is derived from sugarcane, not olive oil, which is important because olive-derived squalane can contain trace fatty acid impurities that feed Malassezia yeast. Sugarcane-derived squalane contains zero fatty acids, polysorbates, or esters that could exacerbate fungal acne.

Can I use The Ordinary Squalane with retinol?

Absolutely — this is one of the best pairings for squalane. Applied after retinol or retinoid treatments, it acts as a lightweight occlusive that buffers irritation and dryness without diluting or interfering with the retinoid's activity. It's a staple recommendation from dermatologists for retinoid users.

Should I apply squalane before or after moisturizer?

After. Squalane is an emollient and lightweight occlusive — it seals in moisture rather than providing it. Apply your hydrating serum and moisturizer first, then use 2-3 drops of squalane as the final step to lock everything in. Applying it to bare, dry skin without hydration underneath won't deliver the results you're looking for.

What's the difference between squalane and squalene?

Squalene (with an 'e') is the unsaturated form naturally produced by human skin, but it oxidizes rapidly and goes rancid when exposed to air. Squalane (with an 'a') is the hydrogenated, shelf-stable version that provides identical emollient benefits without the oxidation risk. This product contains squalane for maximum stability and a 6-month PAO.

Can I use The Ordinary Squalane on my hair?

Yes. A few drops smoothed onto dry hair ends helps tame frizz and add shine without weighing hair down. Because this squalane is completely odorless and lightweight, it won't leave the greasy, heavy residue that thicker oils like argan or coconut oil can. Start with 1-2 drops and add more if needed.

Is The Ordinary Squalane safe during pregnancy?

Yes. Squalane is a naturally occurring component of human sebum and contains no retinoids, chemical sunscreen filters, or any other pregnancy-flagged ingredients. It's widely considered one of the safest skincare ingredients for use during pregnancy and breastfeeding.
