Development of Enzyme-Based Cosmeceuticals: Studies on the Proteolytic Activity of Arthrospira platensis and Its Efficient Incorporation in a Hydrogel Formulation

In the research work, the proteolytic activity of Arthrospira platensis lysate (a type of microalgae that is a valuable source of enzymes and active ingredients in cosmetic applications) was assessed and characterized using kinetics analysis and zymography employing different substrates, pH values and divalent ions. The results showed that incorporation of the Arthrospira platensis extract in the developed hydrogel formulation significantly improved its operational stability over time, which is a significant advantage in enzyme-based product development.
