I believe in each to their own and if it is right for you or whomever, then go for it, , just do considerable research into the provider, their record, and results. It can help with self esteem or prolong careers in the case of celebrities, which am sad to say that we are so appearance driven especially in that industry.

Personally, as much as sometimes I see fantastic results, it is the ones that are botched that scare me and keep me from doing it. As much as I would like to take care of certain things in my appearance, I admit, I am too chicken. So I will have to to ascribe, in particular, to the lines in my face as being my 'character/jolly' lines meanwhile.
