What Is Squalene and What Does It Do for the Skin?
Squalene is a naturally occurring lipid (oil) produced by our own skin cells and is an essential component of sebum—the substance that helps keep skin moisturized, supple, and protected. However, as we age, our natural production of squalene slows down, which can lead to dryness, rough texture, and a weakened skin barrier.
In skincare, squalene is often sourced from plants like olives, sugarcane, rice bran, or wheat germ. It is typically converted into squalane (a more stable, hydrogenated form) to ensure longer shelf life and better absorption. Both squalene and squalane are celebrated for their exceptional hydrating, softening, and skin-repairing properties.
Benefits of Squalene for the Skin
Deeply Moisturizes and Softens
Squalene mimics the skin’s natural oils, allowing it to absorb quickly and deliver long-lasting hydration without leaving a greasy or heavy feeling. It helps improve skin texture, making it feel smooth, soft, and more elastic.
Restores and Strengthens the Skin Barrier
Squalene helps reinforce the skin’s protective barrier, reducing moisture loss and shielding the skin from environmental damage and irritants. A strong barrier is essential for maintaining healthy, resilient skin.
Balances Oil Production
Because it closely resembles the skin’s natural sebum, squalene helps regulate oil levels, making it suitable for both dry and oily skin types. It hydrates without clogging pores or causing breakouts.
Soothes and Calms Sensitive Skin
Squalene has natural anti-inflammatory and antioxidant properties that help calm redness, irritation, and stressed skin. It’s ideal for sensitive, reactive, or inflamed skin conditions, including eczema and rosacea.
Protects Against Premature Aging
As an antioxidant, squalene helps fight free radicals and oxidative stress, two major causes of premature aging. Regular use can help reduce the appearance of fine lines, wrinkles, and dullness over time.
Who Should Use Squalene?
Squalene is gentle, non-comedogenic, and highly compatible with all skin types, including:
-
Dry or dehydrated skin
-
Oily or acne-prone skin
-
Sensitive or reactive skin
-
Mature or aging skin
-
Post-treatment or compromised skin
It’s also suitable for use during pregnancy and for individuals seeking clean, non-irritating skincare options.
How to Use Squalene in Your Skincare Routine
Squalene (or squalane) can be found in facial oils, serums, moisturizers, cleansers, and lip treatments. It can be used both morning and night, either on its own or layered over serums and under moisturizers to lock in hydration.
It pairs well with almost all skincare ingredients, including retinol, vitamin C, hyaluronic acid, niacinamide, and ceramides.
Final Thoughts
Squalene is a highly effective, skin-identical ingredient that delivers intense hydration, barrier support, and antioxidant protection. Whether your skin is dry, oily, sensitive, or aging, squalene offers gentle, science-backed care that leaves your skin feeling nourished, balanced, and radiant.
