Light Emollient / Solvent Hydration & Barrier

What it is & what it does

Isohexadecane is a very lightweight emollient and solvent with a dry finish.
WHAT IT IS: Isohexadecane is a very lightweight emollient and solvent with a dry finish.

HOW IT WORKS: It helps dissolve oil-soluble materials, improves spread and reduces greasy residue. The direct skin benefit is a smoother, lighter feel.

WHY ITS ROLE MATTERS: Emollients soften dry or rough-feeling skin by improving the surface lipid phase and how the formula spreads. Some also form a light film that helps limit moisture loss; this is different from humectants that bind water. The benefit depends on the final mix of oils, waxes, lipids and water-based moisturizers.

A REALISTIC EXPECTATION: A useful emollient can make a routine more comfortable without being a direct acne, pigmentation or wrinkle-treatment active.
