What it is
Isomerized sugar is a sweet syrup made by enzymatically converting (isomerizing) some of the glucose in a starch-derived sugar solution into fructose, yielding a glucose-fructose mixture. The resulting sugars are hygroscopic, so in cosmetics the material acts as a humectant that helps attract and hold moisture at the skin surface. It also contributes to a conditioned, supple skin feel.
Safety & warnings
A simple sugar mixture that is generally well tolerated on skin, with no notable irritation or sensitization concerns at cosmetic use levels.
Origin & sourcing
Plant-derived and processed; produced from starch-based sugars by enzymatic isomerization of glucose into a glucose-fructose blend.
