If you are having Botox, this needs to be prescribed by either a prescribing nurse, dentist, GP or pharmacist. They MUST have a one-to-one consultation with you in person, not remotely as that is illegal. They can then write out a prescription with your name on it to be filled at the pharmacy. The beautician can then inject you.
If you are going to a beautician BE VERY AWARE that they are performing illegal Botox injections if the above has not been followed. I don't care if they produce beautiful results, the fact that they have injected you with illegal products (probably from Korea) means that if something goes wrong, their insurance won't cover them or you so you could not sue if you wanted to because you should have done your homework to make sure they were a Prescriber. Ignorance of the law is no excuse and it will be your own fault.
Also fillers, do not go to someone who is also not a prescriber as yes the beautician can inject you but if it goes wrong and you want the filler dissolved, the dissolver is a prescription only medicine.
So many people are unaware of the law when it comes to Prescription Only Medicines. Another thing, if you go to a beautician who says "I can perform Botox now" they again are acting illegally as they are NOT allowed to keep stocks of Botox and may only inject you with the only that has been prescribed to you.
Too many back street Beauticians/Aesthetics Clinicians (probably those who claim to be medical professionals because they have done a 2 day phlebotomy course) are happy to do it all illegally as they will take their chances as they are making so much money from their clients.
Check the person you are going to see if either registered with CQC or SaveFace.
