Alteromonas ferment extract is an innovative anti-pollution ingredient that chelates heavy metals and has non-toxic anionic polysaccharides, which are used as thickening or structuring agent in tissue engineering, wound management or drug delivery applications. Aging is a physiological process, it is undesirable especially on the skin. Aging leads to weakening of facial muscles and loss of subcutaneous fat and skin laxity, along with wrinkles, prominent lines and sagging skin. Changes in collagen play an important role in reducing skin elasticity. In this case, fibroblast decreases, matrix metalloproteinase increases (responsible for collagen breakdown), and glycosaminoglycans decrease. The objective of the study was to evaluate effects of the anti-aging cosmetic face cream including Alteromonas ferment extract on human dermal fibroblast cells. The outcomes of the characterization analysis have indicated the development of a successful cream formulation with optimum characteristics. No microbial growth was observed. Given the results obtained in the tested conditions, the anti- aging cream is not cytotoxic against fibroblasts 0.5% or less concentration. The dilutions of 0.1% and 0.2% were chosen for evaluation of collagen concentration, because they were the most appropriate concentrations in terms of solubility and lack of cytotoxicity. The treatment with anti-aging cream formulation at 0.1% and 0.2% increased collagen synthesis 57% and 67%, respectively in cell culture.
