What does Glucose Oxidase do in skincare?

Glucose Oxidase is an enzyme that, in cosmetic formulas, is often used as part of a system that can help preserve or stabilize a product. It works by acting on glucose, and some formulas use it for its antimicrobial-supporting role. Its function is technical rather than a direct skin-treatment claim.

Is Glucose Oxidase natural or synthetic?

Glucose Oxidase is an enzyme that is typically produced through fermentation by microorganisms such as fungi, so it is biologically derived rather than chemically synthesized. The cosmetic-grade material is purified for use in formulas. It is generally considered a naturally sourced, processed ingredient.

Is Glucose Oxidase safe?

Glucose Oxidase is used as a cosmetic ingredient at low, functional levels and is generally considered well tolerated. As an enzyme, it is handled within formulas designed for stability. People with specific sensitivities may wish to check the full ingredient list and consult a professional if unsure.
