The method consists of providing a micro-organism able to produce at least one osidic cleavage lyase enzyme; contact green algae polysaccharides, preferably of the Ulva genus, with said lyase enzyme to induce said cleavage; and to recover said cleaved oligosaccharides. According to the invention, the micro-organism is selected from the bacteria group of the Flavobacteriaceae family consisting of the Jejuia pallidilutea strain, the Flavobacteriaceae bacterium strain, the Gaetbulibacter marinus strain and the strain referenced CNCM I-4797. The mixture of cleaved oligosaccharides obtained has a cosmetic activity on the skin cells, including anti-inflammatory, anti-radical, de-pigmenting effects and effects on molecules of the dermal extracellular matrix (such as collagen 1, collagen 4 and fibronectin), on molecules of the epidermal extracellular matrix (hyaluronic acid). |
