What are unsaponifiables and why are they beneficial?

Unsaponifiables are the portion of a fat or oil that does not react with alkali to form soap. In sesame oil, this fraction is concentrated with active compounds like phytosterols, squalene, and tocopherols, which offer enhanced skin benefits such as barrier support, antioxidant activity, and anti-inflammatory effects.

Is this ingredient suitable for sensitive skin?

Sesamum Indicum Oil Unsaponifiables are generally well-tolerated and can be beneficial for sensitive skin due to their soothing and barrier-supporting properties. However, as with any ingredient derived from a known allergen like sesame, individuals with sesame allergies should exercise caution.
