Mesotherapy results may vary according to the skin type of the person and the problem treated. They are usually permanent for 3-6 months. However, depending on the person's lifestyle, skin care and eating habits, the results may last even longer. In some cases, maintenance sessions may be needed at regular intervals after the completion of the treatment period. For lasting results, it is important to maintain a healthy lifestyle following treatment. Also, like any medical procedure, mesotherapy may involve risks and side effects and should be carefully evaluated before being performed.
