Biosurfactants as determinants of the quality anti-aging products

Analysing the possibilities of obtaining biosurfactants and using waste materials as substrates for their production allows us to emphasize that biosurfactants are in line with the ideas of sustainable development and the protection of non-renewable resources. These ideas also apply to the engineering and technology of cosmetic products. For this reason, and because of the multi-functionality of biosurfactants, their role and widespread use in cosmetic formulations is likely to increase. Biosurfactants tend to have good surface properties. Their structural diversity results in differences in biological, antioxidant or biocidal activity. The paper presents the potential of biosurfactants that could be used in the composition of products dedicated to the fight against the problems of ageing skin. Particularly important in the skin ageing process is the fight against radicals and the prevention of collagen loss in the skin. The overall appearance of the skin also depends on the level of hydration and roughness. Biosurfactants also have an effect on the melanogenesis process, controlling hyperpigmentation. A relatively new approach to the fight against skin ageing emphasizes the role of the microbiome, and available research also points to the correlation of biosurfactants with maintaining the correct structure of the microbiome.
