A4 NIGHT WATCH BOOSTER is a highly effective and fast active system for the night. The anti-aging booster works with an innovative Probiotic Technology Complex and 100 percent plant-based ARGAN STEM CELL EXTRACT to transport the smoothing active ingredients exactly where the skin needs them - into the cells. Natural repair mechanisms are stimulated and the skin's protective function is strengthened. The complex supports the production of essential proteins and enzymes with which the skin renews itself, revitalizes itself and regains its radiant appearance. With such intensive moisture, the care booster not only counteracts the loss of cell energy, but also skin damage caused by UV radiation. Unevenness is evened out and the skin can once again react to environmental influences with optimal cell function.
