Treatment length will vary depending on the area being treated. The AY+ is relatively fast and able to complete a large area in under 15 minutes. The number of sessions required to eliminate hair completely depends on the individual. A typical laser hair removal regimen is 5-6 sessions spaced one month apart and then maintenance treatments as needed. Given the efficacy of the AY+, you may need fewer sessions and could go longer before needing a touch-up treatment.
