100% Plant-Derived Squalane

Single-ingredient products have a quiet elegance. No stabilizers, emulsifiers, fragrance, or preservatives—just squalane derived from sugarcane, bottled in Toronto, at a near-charitable price. The Ordinary’s 100% Plant-Derived Squalane makes skincare straightforward.

Squalane science starts with your body. Squalene—the unsaturated precursor—is a major lipid in human sebum, making up roughly 12% of the oily mixture that keeps skin supple, protected, and functioning as a proper barrier. Squalene production peaks in your teens and twenties, then declines. The drop is noticeable by your thirties and significant by your forties. Topical squalane acts as replenishment therapy—replacing what biology removes.

The plant-derived source matters. Traditional squalane came from shark liver oil, which is ethically problematic and increasingly regulated. This product uses squalane derived from sugarcane fermentation to produce a cleaner, higher-purity molecule. Sourcing also affects performance: sugarcane-derived squalane has fewer trace fatty acid impurities than olive-derived alternatives. This makes it safe for those prone to fungal acne, a distinction olive-sourced squalane products cannot always claim.

On the skin, this oil feels like nothing. While the argan oil in The Ordinary’s lineup has weight, squalane is light. A few drops spread across the face and absorb within a minute or two, leaving a subtle healthy sheen instead of an oily film. It has no scent—not even the faint botanical notes found in most plant oils. It is skincare at its most functional.

The mechanism is simple. Squalane works as an emollient and lightweight occlusive. It fills gaps between corneocytes in the stratum corneum, smoothing the skin surface and reducing microscopic cracks where moisture escapes. A clinical study on a squalane-containing serum showed 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 stronger with consistent use.

Recent research shows squalane is not merely passive. A 2025 study in Molecules found that squalane counteracted UVA-induced inhibition of collagen biosynthesis in human dermal fibroblasts and showed anti-inflammatory activity by reducing NF-kB and COX-2 expression. This suggests squalane does more than lock in moisture; it supports skin repair mechanisms during environmental assault.

This product is highly versatile. It works as a final step over hydrating serums to lock in water that hyaluronic acid draws to the skin surface. It buffers dryness and irritation from retinoids without interfering with their activity. You can mix it into foundation for a more luminous look, or use it on dry cuticles, cracked lips, and frizzy hair ends. Because it is odorless and non-reactive, it works with almost every other product in a routine.

However, squalane is not a moisturizer in the common sense. It does not add water to the skin; it prevents water from leaving. Applying squalane to dry, dehydrated skin without a hydrating product underneath seals in dryness. To use it correctly, layer a humectant first (hyaluronic acid or a glycerin-based serum), then apply squalane to trap it. Correct layering yields impressive results; incorrect layering makes the product seem overrated.

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

At $10.40 for 30 mL, the price follows The Ordinary’s disruptive philosophy. Comparable plant-derived squalane oils from premium brands cost $25-40 for the same volume and single ingredient. ECOCERT approval and USDA Bio-based certification provide third-party quality verification that most competitors at this price point lack.

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

This product does not announce itself. It does not tingle, glow, foam, or transform on contact. It does not photograph well for social media. It is, literally, the oil your skin already makes, delivered from a sugarcane plant instead of your sebaceous glands. For people whose skin produces less than it needs, that biological relevance is the point.
