So I would use a dentist due to the fact that they spend a long time studying faces to become dentists!
That being said I have also heard from various sources that some, due to the fact that it's a sideline don't actually do a particularly good job.
My own aesthetics practitioner is actually a GP. That being said I know that he keeps up with all the latest techniques and procedures ( I follow his Instagram page and I see all of the conventions that he goes to ) I would also make sure that I see plenty of before and afters of the things that I wanted doing.
I used a few nurses before I found my practitioner and I wasn't that happy with their work.
When I was researching my neck and face surgery I knew that I wanted a surgeon that would do my work under a local. There aren't many in the U.K. that will do a neck and lower facelift under a local so it was quite difficult to find hom.
He does about 5 of these particular procedures a week along with other operations such as tummy tucks and breast augmentations that do require a general - there were lots of photos of his work online and he is an accredited plastic surgeon that answers questions on the 'real self' website ) this is a starting place for a lot of people who are considering surgery ).
I think the main thing is to make sure that they are a member of 'save face' and that you have examples of their work that you have looked at and are happy with. It's your face after all!
Do make sure that you research what you want and what they are able to deliver.
Good luck, it's not for everyone but it's one of the best things in conjunction with losing a lot of weight that I have ever done for myself.
@billingsuran wow thank you, that's a really kind thing to say - I've never seen it but I've just googled her and I'd be happy to beat a passing resemblance
