Our serum innovation for youthful radiance - inspired by mother cell research. Mother cells are the origin of all other cells from which cell division creates new cells and reaching the climax of their activity at midnight. This process slows down with age, so the skin is renewed less frequently. The unique antioxidant regeneration formula works exactly there: it stimulates cell renewal at night while protecting the skin from free radicals during the day. This creates millions of new skin cells, night after night. The result: the skin is tightened and looks more radiant as regenerated.
