The Simple Sugar Humectant

Glucose is a simple, naturally-occurring sugar used in cosmetics as a gentle humectant and skin-conditioning agent.

Water-loving and skin-friendly, it helps bind moisture at the surface and often serves as a building block in prebiotic and ferment-based systems.

Benefits of Glucose

A gentle, naturally-derived sugar humectant that helps skin hold moisture.

Humectant: Binds water at the skin surface to support hydration.
Skin Conditioning: Leaves skin feeling soft and comfortable.
Prebiotic Building Block: A food source for beneficial microflora in microbiome-friendly systems.
Gentle: Naturally skin-compatible and well tolerated.
Naturally Derived: A simple plant-derived sugar.

How It Works

As a small, highly water-soluble sugar rich in hydroxyl groups, Glucose attracts and holds water at the skin surface (humectancy); it is also readily metabolized by beneficial skin flora, which is why it appears in prebiotic and fermentation systems.

Formulating with Glucose

Glucose is water-soluble and added to the water phase at low levels as a humectant or as a substrate in ferment/prebiotic systems. Observe good manufacturing and preservation practice.

Safety Analysis

Glucose is very well tolerated with an excellent safety profile. As always, substantiate the finished product’s safety (e.g. patch / HRIPT testing) in line with MoCRA requirements.
