Fructan

Description

Fructan is a naturally occurring polysaccharide found in various plants, serving as a storage carbohydrate. It consists of linear or branched chains of fructose molecules linked by β(2→1) or β(2→6) glycosidic bonds. Fructans are classified into different types based on their chain length, including inulin, levan, and graminan. In skincare formulations, fructans, particularly inulin, have gained attention for their potential benefits.

Fructans exhibit prebiotic properties, supporting the growth of beneficial skin microbiota and potentially improving the skin's barrier function. They demonstrate humectant capabilities, attracting and retaining moisture in the skin, which can enhance hydration and reduce transepidermal water loss. Some studies suggest fructans may have anti-inflammatory and antioxidant effects, potentially aiding in soothing irritated skin and combating oxidative stress.

When incorporated into skincare products, fructans can improve texture and provide a smooth, silky feel. They are generally well-tolerated and suitable for various skin types. However, as with any ingredient, individual sensitivities may occur. Fructans are often derived from sources such as chicory root, Jerusalem artichoke, and agave, making them appealing for natural and plant-based formulations.
