This would depend on the lines and their formation. If a single line less units. Multiple lines more units. If the wrinkles extend quite a distance from the lateral canthus (outer part of the eye) more units. It is safer to inject the superior lies ( upper wrinkles) than lower ones. Usual for me, like the others, is 8-9 units. Touch up with 2-3 units two weeks later if patient and I feel the need. Fillers (Cosmoderm or Restylane) if patient wants total correction.
