MUST-KNOW: Procerus muscle, corrugator muscle, depressor supercilii muscle; supraorbital and supratrochlear nerves; and arteries and veins.
FILLER INJECTABLE OF CHOICE: Volbella (Allergan), for superficial etched lines.
WHERE TO INJECT AND WHY: “If you’re injecting the glabellar and periorbital area, or the crow’s feet, those muscles will depress or bring down the eyebrows. So, if you want to get a lift, it’s a good idea to inject those muscles. Then, if you don’t inject the opposing forehead muscle, you’ll see a net effect of a lifting of the eyebrow. That’s because the opposing muscles, the forehead or frontalis muscles, will raise the brow,” Dr. Manolakakis says.
WHAT CAN GO WRONG ANATOMY-WISE: “Typically, if you’re injecting a neurotoxin into a blood vessel, the neurotoxin just will not work, and you will most likely get a bruise,” he says. “If you inject filler into one of the vessels, you can potentially get skin necrosis or even blindness, as these vessels connect with the central retinal and ophthalmic retinal arteries and veins.”
