The Science Behind Squalane: The Hydrating Hero in Your Skincare Routine

When it comes to keeping skin soft, plump, and healthy, hydration is key. While there are plenty of ingredients out there that promise dewy, moisturized skin, few have the science—and the results—to back it up quite like squalane.

If you’ve seen this ingredient popping up on skincare labels and wondered what it is, where it comes from, or why it’s suddenly everywhere, you’re not alone. Let’s dive into the science behind squalane, what makes it so effective, and why it deserves a permanent spot in your skincare routine.

What Is Squalane?

Squalane is a lightweight, skin-compatible emollient derived from squalene (with an e), a naturally occurring compound in our skin’s own lipid barrier. Our bodies produce squalene as part of the sebum that keeps skin lubricated and protected. However, like many things our bodies do well in youth, our natural squalene production begins to decrease in our 20s and 30s.

The raw form—squalene—is unstable and prone to oxidation, which is why it’s hydrogenated into squalane, the more stable, shelf-ready version used in skincare products. This subtle chemical change makes it longer-lasting and far less likely to go rancid, while still delivering the same moisturizing power.

Most modern skincare-grade squalane is sustainably derived from plant-based sources, like olives, sugarcane, or rice bran. That means it's safe, ethical, and suitable for all skin types.

What Does Squalane Actually Do?

Squalane’s real magic lies in how closely it mimics your skin’s natural oils. Because it’s biocompatible, your skin recognizes it and soaks it up easily without clogging pores or causing irritation. It works by replenishing lost moisture and reinforcing the skin’s natural barrier. It helps reduce visible signs of aging such as fine lines, wrinkles, and dullness, while helping to maintain soft and supple skin.

Here are a few science-backed benefits of incorporating squalane into your skincare:

• Deep hydration without heaviness – Squalane is incredibly lightweight and non-greasy. It sinks in fast and leaves skin feeling soft, never sticky.
• Strengthens the skin barrier – A healthy lipid barrier helps lock in moisture and keep environmental irritants out.
• Antioxidant properties – Squalane helps defend against oxidative stress, which contributes to premature aging.
• Soothes sensitivity – It’s known for being gentle and calming, making it a great option for those with redness, dryness, or sensitive skin.
• Balancing for all skin types – Yes, even oily or acne-prone skin. Because squalane is so similar to your skin’s own sebum, it can actually help balance overproduction of oil.

Why You Should Care

If you’ve ever battled dry patches, flaky texture, or tight-feeling skin—even after moisturizing—it’s likely that your skin barrier is compromised. Ingredients like squalane don’t just sit on the surface; they nourish the skin at a deeper level, helping restore that essential barrier function.

What sets squalane apart from heavier oils and butters is its universality. Whether you’re 25 or 65, oily or dry, living in a humid climate or battling winter wind, squalane fits seamlessly into just about any routine. It layers beautifully under makeup or sunscreen, and pairs well with actives like retinol, AHAs, or vitamin C.

How to Use It

Squalane is versatile—it can be found in moisturizers, serums, oils, and even cleansers. For best results, apply it as a final step in your routine to lock in hydration, or mix a few drops into your favorite cream. Look for products that list squalane high on the ingredients list, especially if hydration is a primary concern.
