A nurse can inject filler or toxins in a beauty clinic or medspa, as long as he/she has a physician medical director at that facility. My overall recommendations, however, would be to seek the services of an experienced plastic surgeon for the following reasons. I think the key with injectables lies in truly understanding the anatomy of the injected area, and more importantly the variability in the anatomy between patients -- for brows, eyelids, cheeks, lips, and anywhere else you plan on receiving a filler or toxin. This includes having a firm understanding of the origin, insertion, and action of each muscle around which filler will be injected, the vascular (blood vessel) network in the region, the underlying bone anatomy, and the patient variability therein. As an Aesthetic Fellowship-trained Plastic Surgeon, I feel that I have an advantage when injecting since I operate in the face for cosmetic browlifts, facelifts, and eyelid surgeries and also when repairing those areas following injury. I feel this allows a unique perspective to the anatomy since I commonly dissect under the skin and see the underlying structures directly. For me, this helps guide where to inject and where not to. Good luck. Mark K Markarian, MD, MSPH Harvard-trained Aesthetic Plastic Surgeon
