This group is composed of highly effective skincare ingredients which are derived from diverse natural sources: plants, grains, fungi, and yeast. The majority of carbohydrates incorporated in beauty formulas are glucans, long chains of glucose molecules that are connected together. Being derived from plants or microorganisms these compounds are pretty familiar to our body cells, so they don’t cause any dermal irritation or sensibilization. Some of the glucans are even utilized in the food industry. Obviously, they are safe in concentrations used in cosmetics.
Glucans are a total win-win for all types of complexions. First, these carbohydrates are exceptional moisturizers. Being applied on the top layer of the epidermis they form a delicate layer on it and, thus, hinder water evaporation from the face surface. On the other hand, due to their chemical structure, they have the ability to bond water molecules and keep them inside dermal layers. The double moisturizing effect of these molecules protects skin from dehydration, consecutive dermal destruction, and wrinkle formation.
Next, they are potent antioxidants and anti-inflammatory agents. These carbohydrates efficiently hunt and neutralize free radicals, which are the main cause of collagen quantity drop and wrinkling. Actively penetrating the epidermis and dermis they also stop the harmful cascade of inflammatory processes and prevents degradation of the skin frame.
Also, these compounds are involved in the inhibition of melanin production. In this way, they battle hyperpigmentation, one of the most common problems of aging skin. And this is not the end. Some carbs are incorporated into beauty formulations to serve as prebiotics (food for dermal microflora). Microorganisms are an essential part of our body's uppermost layer and their bioactivity straightforwardly affect skin integrity. This is why microbiome-friendly beauty formulas are one of the trends of 2021.
Taking into account all these impressive benefits of polymeric carbs many famous beauty experts mention glucans as must-have ingredients of result–delivering skincare products.
Dextran is a polysaccharide (polyglucan) from glucose units composed of α-C1-C6 linked chains of different lengths. Dextrans polymer chain length varies from very short (water-soluble) to very long (insoluble).
Mannose is a simple monosaccharide sugar, a stereoisomer of glucose found in many plants and the human body. It plays an essential role in biological processes in the human body, particularly in protein glycosylation.
Microcrystalline cellulose is purified, isolated colloidal crystalline cellulose derived from fibrous plants. It is a white, free-flowing powder, odorless, and insoluble in water.
