The natural Euglenia Gracilis (pseudo-microalgae) often lives in fresh water and is provided with vegetable and animal characteristics. The microalgae has a high survivability even in extreme situations and is able to feed and to metabolize itself in various ways. Biotechnologically recreated, we use exactly this function in order to stimulate the important factors of the metabolic process of the skin and to strengthen its regenerative abilities. The cell metabolism is activated through stimulation of the release of calcium and increase of energy balance. Signs of tiredness are visibly reduced, the skin is fresher and gets more resilience.
