Abstract
Skin as principal barrier protects our body from the inside and outside environmental aggressions represented principally from air pollution and the pathogenic microorganisms.The fundamental protective parts of the skin are the Stratum Corneum and the dermal compartment largely composed of dense collagen-rich fibrils which, embedded into the Extracellular matrix, provide structural and mechanical support.This complex structure degrades during the aging processes due to genetic factors and the environmental polluted environment .To protect and try to rejuvenate the skin both women and men are looking for cosmetic products made by natural ingredients,produced by sustainable technologies and packed by containers able to safeguard human health and the environment. Polysaccharides seem to be the best ingredients to make natural-based active ingredients and carriers for Pharmaceutical and Cosmetic use, being skin- and environmentally-friendly,and obtainable at low cost from the food waste. At this purpose, a new category of biocosmetic products has been proposed, which are made by smart non-woven tissue-carriers, embedded by micro-nanoparticles of nanochitin-nanolignin, encapsulating different active ingredients. Natural polysaccharides used as carriers and active ingredients characterize the different activities of these innovative cosmeceutical-tissues. So doing it could be possible to reduce part of the food waste, safeguarding natural raw materials and biodiversity of our planet for the future generations.
