I would say have it done by a registered practitioner, but it doesn't need to be a plastic surgeon. It depends on cost as to how much you need. The nurse I use gives me 2 rows in the forehead, some by each eye and also some in the jaw to reduce the size of the master muscle. I also have some filler in the lips, cheeks and nasolabial lines and all of that comes in well under £1000, most of which is the fillers!
