Effects of polysaccharide-based formulations on human skin

Abstract

The polysaccharides, mainly from natural sources, have been widely used in cosmetic area due to their multifunctional properties, playing a large role in the research and development of cosmetics products. The knowledge of the skin biology allows the identification of which active ingredients are important for the maintenance of its integrality and barrier function, essential to skin health. So due to the polysaccharides protective effects on the skin, the development of cosmetic formulations with these ingredients like hyaluronic acid, algae, and others obtained by biotechnology process could improve the efficacy of the formulations, maintaining the skin in good conditions. In addition, some polysaccharides can also improve formulation stability and sensorial properties. The data from clinical studies showed that the polysaccharide-based formulations promoted the transepidermal water loss reduction, protecting the skin barrier function. This way, they are interesting active ingredients to develop effective cosmetic formulations for skin protection and maintenance of its structure integrality.
