Vexum.SL is clinically proven to radically reduce the thickness, volume and appearance of a double chin, while restoring normal contour to the upper neck. The active ingredients in Vexum.SL, polymannuronate and prolamins, work by tightening the skin on contact as well as other ingredients that work over the long term to produce lasting effects. The proven science behind Vexum.SL means that we can now reduce the volume and thickness of a double chin and stave off indications for a looming face lift. Bringing back the natural curve of our neck is now easy and accessible by simply applying a topical cream twice daily.
