There is quite some controversy and confusion regarding who is allowed to perform certain aesthetic procedures such as dermal filler injections. This is due to the absence of global or continental regulations regarding who is entitled to perform non-invasive cosmetic procedures. National guidelines and regulations differ strongly from each other.

Stronger regulations would however make non-invasive cosmetic procedures much safer for the patient. It would create more awareness about the potential dangers of filler injections and other procedures performed by unqualified practitioners. In many regions, illegal injectors and beauticians administer dermal fillers without a license nor any control.
