Why learn additional treatment areas? As an Aesthetics Practitioner, your skill set is basically your product offering. You know how to do anti-wrinkle injections on the forehead, great – that’s already a money making machine but if you want to go for the BIG BAG? You need to continuously extend the range of treatments you offer. It won’t just bring you new customers but serves as the perfect opportunity for the existing clientele of yours that need it.
