Bacterial cellulose (BC) is a natural homopolysaccharide made of repeating with B‐(1→4) linkages [57]. Bacterial cellulose shares all the properties shown by plant cellulose. The plant cellulose complexes with other natural polymers like hemicellulose and lignin, but BC is produced and obtained in relatively pure form. BC can be from several groups of bacteria like Gluconacetobacter xylinus, Gluconacetobacter hansenii, Glucoacetobacter pasteurianus [58, 59]. BC is used to make biomembranes that can be used in medicine and cosmetics and to its high degree of hydration has enhanced its uses in moisturizing creams [60]. BC shows skin regeneration activity, and its biopolymer has been projected for the development of skin moisturizers and skin repair [61]. In a study carried out on 30 volunteers, BC masks have been checked for the treatment of dry skin and improving skin hydration, and its in vivo efficacy was checked after single applications [61].
