Dextran

Description

Dextran is a complex polysaccharide composed of glucose molecules, primarily linked by α-1,6 glycosidic bonds. This versatile ingredient, derived from bacterial fermentation of sucrose, has gained significant attention in skincare formulations due to its multifaceted benefits. Dextran functions as a humectant, attracting and retaining moisture in the skin, which helps maintain hydration and improve skin barrier function. Its molecular structure allows it to form a protective film on the skin's surface, reducing transepidermal water loss and enhancing overall skin texture.

In addition to its hydrating properties, dextran exhibits anti-inflammatory and soothing effects, making it suitable for sensitive and irritated skin conditions. It can help mitigate redness and discomfort associated with various dermatological issues. Dextran also demonstrates antioxidant capabilities, potentially protecting skin cells from oxidative stress and environmental damage. Its biocompatibility and low allergenic potential make it a safe choice for a wide range of skin types.

In skincare formulations, dextran is often used in concentrations ranging from 0.5% to 5%, depending on the desired effect and product type. It synergizes well with other hydrating ingredients and can enhance the overall efficacy of skincare products.
