Ingredient Spotlight: Squalane – Why It's One of Skincare's Most Loved Oils
Squalane is one of the most versatile emollients used in modern cosmetic formulation. Loved for its exceptionally lightweight feel, excellent stability and elegant skin finish, it helps create moisturisers, serums and facial oils that feel luxurious without being greasy.
Unlike many heavier plant oils, squalane absorbs quickly while leaving skin feeling soft, smooth and conditioned. It is suitable for almost every skin type and is frequently included in premium skincare designed for hydration, barrier support and everyday skin comfort.
Its compatibility with a wide range of cosmetic ingredients makes squalane a favourite among formulators developing lightweight yet nourishing skincare products.
What is squalane?
Squalane is the stable, hydrogenated form of squalene, a lipid that naturally occurs in human sebum. While squalene plays an important role in maintaining the skin's protective barrier, it is relatively unstable and readily oxidises when exposed to air.
Hydrogenation converts squalene into squalane, creating a highly stable cosmetic ingredient that retains its excellent emollient properties while offering significantly improved shelf stability.
Today, cosmetic-grade squalane is commonly produced from renewable plant sources such as olives or sugarcane, making it a popular choice for modern skincare formulations.
Squalane vs Squalene
| Squalene | Squalane |
|---|---|
| Naturally present in human sebum | Hydrogenated cosmetic ingredient |
| Oxidises relatively easily | Highly stable against oxidation |
| Rarely used directly in skincare | Widely used in cosmetic formulations |
| Shorter shelf stability | Excellent shelf stability |
| Natural skin lipid | Lightweight cosmetic emollient |
Why formulators love squalane
1. Lightweight hydration without heaviness
Squalane helps soften and condition the skin without leaving the rich or greasy after-feel associated with many traditional plant oils.
This makes it particularly suitable for lightweight moisturisers, facial oils and daily hydration serums.
2. Creates a luxurious skin feel
One of squalane's biggest advantages is the elegant sensory experience it provides. It spreads easily across the skin, improves slip during application and leaves a silky, smooth finish that consumers often associate with premium skincare.
4. Exceptional formulation stability
Unlike many botanical oils, squalane offers excellent oxidative stability. This makes it particularly attractive for formulators seeking long-lasting, premium products with reliable shelf stability.
5. Compatible with almost every skincare routine
Squalane works beautifully alongside humectants, barrier-support ingredients, antioxidants and active ingredients, making it one of the easiest cosmetic oils to formulate with.
Typical use level
- 1–5% in lightweight lotions
- 3–10% in moisturisers
- 5–20% in facial oils
- Up to 100% as a standalone facial oil
The ideal usage rate depends on the desired skin feel and the overall formulation.
Formulation considerations
Solubility
Squalane is oil-soluble and should be incorporated into the oil phase of emulsions or blended directly into anhydrous formulations.
Heat stability
Its excellent stability allows it to tolerate normal cosmetic manufacturing temperatures.
Texture
Squalane reduces greasiness while improving glide, helping create elegant formulations with a refined skin feel.

Common formulation mistakes
Using too much alongside heavy oils
Although lightweight, combining high levels of squalane with richer oils may create a heavier skin feel than intended.
Forgetting overall oil phase balance
Squalane should complement the formulation rather than dominate it. Balancing esters, botanical oils and emollients often produces a more elegant finished product.
Assuming every skin type needs the same percentage
Lighter facial serums typically benefit from lower use levels, while facial oils may comfortably contain much higher concentrations.
