I am not saying go get the stuff and practice in your bedroom and for the benefit of younger board members DO NOT try and do that it could be very dangerous.
But in the U.K. at least you don’t need to be a dr to administer it. It’s very easy for anyone to set themselves up as a aesthetic clinic and offer non invasive procedures like this. So on theory you must be able to go on a course and learn how to administer it correctly and safely. Over the long term that’s a big saving in cash when you compare costs of the base product with clinic costs.
