Local anesthesia is generally not necessary. The number of injections required depends on each patient's needs and goals. It is estimated that 12 to 20 small injections per session are sufficient for most patients, performed over 2-3 sessions, to achieve optimal results.
Each session is performed, on average, one month apart. Patients with advanced cases of double chin may require up to 50 injections per session, with appointments as often as every two weeks. In these cases, the number of sessions may reach up to six.
