Aestheticians have no medical training and would "never" under any circumstances be able to inject a patient with Botox or any filler. LPN's are not licenced to inject patients.
I agree that it's now "buyer beware" for the public seeking these types of aesthetic procedures. Just remember if it sounds too good to be true...there's a reason.
Go to a plastic and cosmetic surgeon or dermatologist who is experienced so you actually do get what your paying for.
