Galactoarabinan
Galactoarabinan is a gentle, plant-derived polysaccharide used in UK skincare and haircare to improve texture, hydration and product feel. It is a natural alternative to synthetic polymers, giving a silky finish without heaviness. You’ll often find it in moisturisers, serums, masks and styling products.
How it works in skincare
In cosmetics galactoarabinan functions as a film-former, humectant and texture enhancer. It helps bind water to the skin’s surface, creating a smooth, invisible veil that improves slip and reduces the tacky feel of many formulations. It also stabilises emulsions and can subtly tighten the skin’s appearance for a refined finish, making it a popular ingredient in both daily moisturisers and premium anti-ageing products across the UK.
