Dextrin

Dextrin is a plant-derived carbohydrate that plays a versatile and supportive role in cosmetic formulations. Sourced from natural starches like corn, potato, or tapioca, this polysaccharide is primarily used to enhance the texture of skincare products, stabilize complex formulas, and help deliver key benefits to the skin, making it a quiet but crucial component in creating elegant and effective skincare.

Natural Science

Scientifically, dextrin is a polymer of D-glucose units linked by glycosidic bonds. It is created through the hydrolysis of starch, a process that breaks down the large starch molecules into smaller, more soluble fragments. This process can be achieved using heat, acid, or enzymes, resulting in different types of dextrin with varying properties.

Because of its variable molecular size and structure, dextrin can be tailored for specific functions. In skincare, its ability to dissolve in water and form gels or films makes it an invaluable formulation tool. It acts as a binding agent, helping ingredients cohere, and as a suspending agent, keeping particles evenly dispersed throughout a product.

Benefits of Dextrin in Skincare

While often working behind the scenes, dextrin offers several benefits that contribute directly to both product performance and skin health. It functions as a multipurpose ingredient that improves a formula's sensory feel while also providing absorbent and soothing properties that are beneficial for maintaining a balanced complexion.

• Texture and Stability: Dextrin is an excellent stabilizer and viscosity-controlling agent. It helps create smooth, cosmetically elegant textures in creams and serums, preventing them from separating and ensuring a consistent application every time.
• Absorbent Properties: It has the ability to absorb excess oil from the skin's surface. This makes it a useful ingredient in formulations for oily or combination skin types, helping to reduce shine and provide a more matte finish without causing dryness.
• Soothing and Prebiotic Potential: As a polysaccharide, dextrin can have a soothing effect on the skin. Furthermore, certain carbohydrates can serve as a food source for beneficial microorganisms, suggesting a potential role in supporting a healthy and balanced skin microbiome.

How Its Used in Nuebiome Products

At Nuebiome, we utilize dextrin for its unique formulation and skin-supportive benefits. Its ability to stabilize and improve texture allows us to create sophisticated formulas that feel incredible on the skin. You can experience the benefits of this ingredient in our Biome Balancing Creamy Cleanser and Empris-Peony™ Biotic Resurfacing Night Serum.

Research

Recent scientific studies highlight the advanced potential of dextrin in dermatological and cosmetic applications. Research has demonstrated its value in creating sophisticated nanohydrogels for the prolonged topical delivery of active ingredients, enhancing their efficacy on the skin. Other studies explore its use in biocompatible hydrogel adhesives for wound healing, underscoring its compatibility with skin tissue. Furthermore, understanding how skin-related bacteria like Staphylococcus aureus metabolize carbohydrates can inform how ingredients like dextrin may influence the skin's delicate microbiome, paving the way for next-generation, microbiome-friendly skincare.

Frequently Asked Questions about Dextrin

What does dextrin do in skincare?

In skincare, dextrin primarily functions as a texture enhancer, stabilizer, and absorbent. It improves the feel of products, prevents ingredients from separating, and can absorb excess oil from the skin. It may also offer mild skin-soothing benefits.

Is dextrin a safe ingredient?

Yes, dextrin is widely regarded as a safe ingredient for use in cosmetics. The Cosmetic Ingredient Review (CIR) Expert Panel has assessed it and concluded that it is safe in the present practices of use and concentration in cosmetic products.

Is dextran safe for skin?

Yes, dextran, a related but different polysaccharide, is also considered safe for cosmetic use. It is often used in skincare for its excellent hydrating and film-forming properties, helping to lock moisture into the skin.
