We recommend using your handset once a week for the first 12 weeks. You can also use it twice per week for faster results. After this period, use the handset once a month for 3 months or until satisfied. To maintain hairless smooth skin after that, you may need to use the handset once every 2 to 3 months or as needed.It is not necessary to treat the area more than once a week. This is because IPL is most effective in the hair growth phase, and some hairs may be dormant during treatment. This is why it is recommended to do 12 consecutive weeks of treatment.If you are struggling to see results, try a higher intensity and use your handset 2 times per week (never more). Do this until you see some results, then you can reduce your frequency back to once per week.
