With age your skin becomes slower at creating new cells. Thus, the skin begins to sag, which affects the structure of the skin and makes it less firm. Therefore, we\'ve created a 50+ Serum, for the 50+ series, filled with stem cells. Stem Cells are small miracle workers when it comes to renewing the skin: They both repair and develop new cells, which provide you with more and better skin cells - and at the same time, they reduce skin aging. In this way, the stem cells improve your skin\'s elasticity and make your skin smoother. Additionally, 50+ Serum contains two types of hyaluronic acid that work effectively on the skin from the inside out. One of the hyaluronic acids has a low molecular weight, which makes it penetrate the skin easily and it also binds moisture to the skin. The other type of hyaluronic acid has a high molecular weight and nourishes and softens the surface layer of the skin. So, with the 50+ Serum your skin will receive luxurious care and a proper moisture boost that minimize wrinkles and make skin appear younger. AllergyCertified, vegan, dermatologically tested, and fragrance free.
