What it is
Glycosyl Trehalose is a carbohydrate composed of glucose units attached to trehalose, a stable disaccharide found in many plants and microorganisms. In skincare it serves as a humectant, drawing and holding moisture at the skin surface to help maintain hydration and a comfortable feel. It is often paired with hydrogenated starch hydrolysate in moisture-retaining complexes.
Safety & warnings
Sugar-based humectants like glycosyl trehalose are generally very well tolerated and gentle, with a low likelihood of irritation. It is not considered comedogenic.
Origin & sourcing
Produced enzymatically from starch and trehalose, both of which originate from plant or microbial carbohydrate sources.
