Squalene
Ingredient Info
Squalene is a natural oil found in human skin sebum (about 13% of it) and in certain fish and plant oils. In skincare products, it works as a moisturizer and emollient to hydrate and soften your skin.
Benefits
- Hydrates and moisturizes skin
- Softens and smooths skin texture
- Antioxidant properties may help protect skin from damage
- Naturally present in skin, so generally well-tolerated
Science: The Cosmetic Ingredient Review Expert Panel confirmed in 2023 that squalene is safe for use in cosmetics at standard concentrations. Research indicates antioxidant and skin-hydrating properties, with potential benefits for photoaging repair, though most clinical evidence comes from animal models and lab studies rather than large human trials.
