Best For
All skin types, including oily & acne-prone
Comedogenic Rating
0–1 out of 5 — won’t clog pores
Typical Concentration
2–8% in daily moisturizers
Squalane is a lightweight, stable oil that closely mimics squalene — a lipid your skin naturally produces as part of its own protective barrier. Because it’s chemically so similar to what skin already makes, it integrates into the skin’s lipid matrix rather than just sitting on top, and it’s earned a reputation as one of the gentlest, most broadly tolerated facial oils available.
What squalane does for skin
- Hydrates deeply without heaviness — research shows it can increase skin moisture significantly while reducing transepidermal water loss
- Won’t clog pores — squalane has one of the lowest comedogenic ratings of any facial oil (0-1 on a 0-5 scale), making it suitable even for oily and acne-prone skin
- Supports the skin barrier — integrates into the skin’s own lipid structure rather than sitting purely on the surface
- Offers antioxidant protection — emerging research shows it helps protect against UV-induced damage to collagen production
- Acts as a carrier for other ingredients — can help improve how well other actives in a formula are retained by the skin
What percentage of squalane should you use
In formulated products, squalane is effective from as low as 1%, with 2-8% typical for daily moisturizer use. Pure squalane facial oil is, naturally, 100% squalane — apply a few drops as the final step in your routine.
| Concentration | Where It’s Used | Notes |
|---|---|---|
| 1% | Formulated products | Minimum effective concentration |
| 2–8% | Daily moisturizers | Typical range for everyday use |
| 100% | Pure squalane facial oil | Apply a few drops as the final step in your routine |
Who should use squalane
Genuinely suitable for every skin type, including oily and acne-prone skin that might otherwise avoid facial oils. Particularly useful for chronically dry skin, mature skin, and those in harsh, low-humidity climates.
A practical sourcing note
Squalane can be derived from plants (sugarcane, olives, rice bran) or, historically, from shark liver — modern skincare has largely shifted to plant-based sourcing, which is worth checking for if sourcing matters to you.
Olive-derived squalane can occasionally contain trace impurities that some people with fungal acne (malassezia) find aggravating — sugarcane-derived squalane is generally considered the safer choice if that’s a concern for you.
What to pair squalane with
Squalane layers well with virtually every other ingredient, or use it alone as a simple, effective moisturizer.
Frequently asked questions
Is squalane good for oily skin?
Yes — despite being an oil, its non-comedogenic nature means it won’t clog pores, and providing adequate hydration can actually help regulate excess oil production.
What’s the difference between squalane and squalene?
Squalene (with an “e”) is the naturally occurring, less stable form found in your skin’s sebum; squalane (with an “a”) is the hydrogenated, shelf-stable version used in skincare.
Can squalane be used every day?
Yes, it’s gentle enough for daily morning and evening use.
