The time it takes to complete a given procedure relies largely on the procedure being preformed and on the competency of the technician performing it. Usually, appointments are scheduled for one-and-a-half to two-and-a-half hours. Time for applying design guides and topical anesthetics will also factor into the time allotted for the chosen procedure. Considering that the numbing agents (if used by the technician), take anywhere from fifteen to forty-five minutes to become effective, the time spent applying the permanent cosmetic procedure consumes only a minimal portion of the time set aside for the entire appointment. The completion and review of forms, the taking of photographs and discussions regarding aftercare maintenance requirements are also tasks that require time allotment.
