Aloe Barbadensis Leaf Polysaccharides

What is Aloe Barbadensis Leaf Polysaccharides?

Aloe Barbadensis Leaf Polysaccharides consist of large carbohydrate polymers extracted from the mucilaginous gel within Aloe barbadensis (aloe vera) leaves. These bioactive molecules, mainly long-chain mannans and hemicelluloses, originate from a succulent plant native to arid regions. In cosmetic products like lotions, gels, and serums, they function by absorbing water to swell and create a flexible, breathable layer on the skin's surface. This mechanism enhances product spreadability and provides a barrier that minimizes transepidermal water loss without greasiness. Their gentle, plant-based nature suits water-based formulations, contributing to a lightweight feel while supporting overall skin comfort in daily routines.
