CellBeauté begins to work from Day 1 with the full visible impact developing over 90 days. Why 90 days? Skin regeneration comes from a sequence of steps and the coordination of different cell types, signalling molecules and synthesis of extracellular components. Each step takes time, with more benefits becoming visible month after month. Almost everyone will see the impact of CellBeauté within 90 days. With ongoing use, your skin renewal will continue and be maintained. The following are some of the visible differences that you can expect to see.
