The purpose of mesotherapy application sessions varies according to the application area, gender and age. There are cases where it is not recommended to do more than just 2 or 3 sessions a year, and there are also applications where 5-6 sessions are done with 10-day intervals and then a repeat dose is recommended in certain months of the year. The effect begins to be observed with the first session, and the effectiveness varies according to the structure of the person and the substances applied.
