The number of sessions depends on your skin and hair type. Typically, a minimum of 6 sessions is required.
Depending on your hair, skin type, and body area being treated, you will require treatments at 4-6 weeks intervals. For the facial area, treatments can be done at 2-4 week intervals. Each part of the facial and body area has a different growing cycle, so hair reduction will vary depending on what stage your follicles are in at the time of the treatment.
