Dextran is a type of carbohydrate polymer that is commonly used in the cosmetics industry as a humectant and thickening agent. It is derived from natural sources such as starch or sucrose through a process of bacterial fermentation. Dextran has a high molecular weight and is water-soluble.

• Moisturizing: Dextran is a humectant, which means that it helps to attract and retain moisture on the skin. This makes it an ideal ingredient for hydrating skincare products.

• Thickening: Dextran is a thickening agent that can increase the viscosity of formulations. This makes it useful for creating creams, lotions, and other skincare products with a desirable texture.

• Soothing: Dextran has anti-inflammatory properties that can help to soothe and calm irritated skin. This makes it useful for products that are designed to treat skin conditions such as eczema or psoriasis.

• Anti-aging: Dextran has been shown to stimulate collagen production in the skin, which can help to reduce the appearance of fine lines and wrinkles. It can also help to improve skin elasticity, resulting in a more youthful-looking complexion.

Overall, dextran is a versatile ingredient that can be used in a variety of skincare products to provide moisturizing, thickening, soothing, and anti-aging benefits.
