Dextran
Dextran
Dextran is a naturally derived polysaccharide produced through the fermentation of sugars by certain bacteria. In skincare, it is used as a film-forming and moisturising ingredient that helps improve skin hydration and leave the skin feeling smoother and more comfortable. It is also valued for its ability to stabilise formulations and enhance the delivery or performance of certain active ingredients, particularly peptides. Dextran is commonly found in serums, eye creams, and anti-ageing formulations where it contributes to both product performance and skin conditioning.
🛡️
Safety: Generally well tolerated by most skin types, including sensitive skin. Allergic reactions are rare, although individuals with known sensitivities to fermentation-derived ingredients should discontinue use if irritation occurs.
