Squalane

Squalane: what it is, how it works, and why your skin loves it

Squalane is a silky, skin-friendly oil derived from squalene, a lipid naturally found in your skin’s sebum.

Understanding squalane and where it comes from

Through hydrogenation, squalene becomes squalane, a more stable and long-lasting ingredient perfect for skincare.

While shark liver oil was once a source, modern squalane is now mainly plant-based, extracted from olives, sugarcane, rice bran, or wheat germ. The result is a clean, cruelty-free ingredient that feels weightless but delivers lasting hydration (1).

Because it mimics your skin’s own oils, squalane works for virtually everyone. It moisturises without clogging pores, making it a favourite for both dry and oily skin types.

Key benefits for skin and hair

Squalane helps skin hold onto moisture, leaving it smooth, soft, and supple. Its natural antioxidant qualities may also protect against environmental stress, pollution, and early signs of ageing such as dullness or fine lines.

It supports the skin’s barrier, soothes dryness, and enhances natural radiance. With consistent use, skin may appear plumper and more balanced.

For hair, squalane adds shine and softness while helping prevent breakage. A small amount can smooth frizz and restore moisture without leaving residue (2).

Squalane and eczema

Squalane may be a helpful ingredient for people with eczema-prone skin. Because it closely resembles the skin’s natural oils, it helps strengthen the moisture barrier and reduce water loss, which are key concerns for dry or irritated skin. Its lightweight texture makes it suitable for sensitive complexions, offering hydration without heaviness or residue (3).

How to use squalane in your routine

Squalane is easy to add to any routine. Apply a few drops to clean, slightly damp skin to help lock in hydration. It layers beautifully under moisturiser, sunscreen, or makeup.

For hair, use a small amount through the mid-lengths or ends to add shine and protection, especially after washing or before heat styling.

Is squalane safe for all skin types?

Yes, squalane is generally considered safe and well tolerated. It is non-comedogenic (4), meaning it does not clog pores, and its lightweight texture suits every skin type, including sensitive or acne-prone skin (5).

Still, it is wise to do a patch test the first time you use it. Opt for 100 percent plant-derived squalane for a cruelty-free option.

Things to keep in mind before using

Although rare, some people may experience mild redness or irritation. If this happens, stop using the product and consult a skincare professional.

Those with chronic skin concerns such as eczema, psoriasis, or rosacea should check with a dermatologist before introducing new products.

The bottom line

This simple yet effective oil has earned its place as a skincare staple.

Squalane is a multitasking hydrator that feels light, absorbs quickly, and leaves skin beautifully soft. It helps strengthen the skin’s barrier, smooth texture, and boost glow while also working wonders for dry or frizzy hair.
