Our take
Is Glycereth-18 a Good Ingredient?
It's a dependable, water-soluble humectant that boosts surface hydration and improves slip, which earns it a Good rating for proven cosmetic performance and stability. It's low-irritating and works well across formats, but doesn't have the kind of exceptional clinical backing that would move it to Great.
