Karin Maier has been joyfully and proudly running her successful medical beauty institute in the centre of Stuttgart for many years. Her customers often leave the studio saying: “Once you’ve tried Belter, you never go back!”. Her entrepreneurial autonomy is not just a profession; it is pure passion. “When you’re self-employed, downtime is a step backwards – so you must be more than willing to respond constantly to industry innovations yourself to maintain the satisfaction of the customers who make your new cosmetics studio a success.”
