Kojyl Glucoside

Kojyl glucoside is a modified form of kojic acid, a naturally derived compound traditionally used in skincare. It functions as an antioxidant, meaning it helps neutralise free radicals — unstable molecules that can damage skin cells and contribute to visible ageing and inflammation.This ingredient is created by combining kojic acid with glucose, a modification that aims to improve stability and reduce irritation potential compared to kojic acid alone. It is typically incorporated into formulations as a protective and soothing agent.

Kojyl glucoside works by donating electrons to free radicals, effectively stabilising them and preventing them from causing cellular damage. This antioxidant action helps protect skin proteins and lipids from oxidative degradation, which can otherwise contribute to loss of elasticity and visible ageing.The ingredient is thought to function primarily as a protective agent rather than an active transformer of the skin, making it well-suited to supportive skincare regimens.

Kojyl glucoside is typically found in serums, moisturisers, and essences. Use as directed by the specific product formulation — usually as part of a daily or twice-daily routine. It pairs well with other antioxidants and hydrating ingredients, and can be layered with vitamin C serums or niacinamide-based products.

Kojyl glucoside is generally well-tolerated across most skin types. As with any antioxidant ingredient, patch test if you have known sensitivities to kojic acid or similar compounds.
