For safety, always start and end treatments with the intensity and frequency at zero. The light will not fire at these settings. Avoid touching power button when adjusting settings.


1.Start with lowest settings of 1 intensity and 1 frequency. Perform a test spot on desired treatment area. Expect to feel a hot snapping sensation. This sensation becomes more intense with increase in settings. Immediately check area after test spot then wait 30 seconds to visualize any redness or change in color over time. Stop treatment if intolerable.do not have light pulse repeatedly on one spot. Allow 
breaks between pulses and keep light moving around treatment area. For smaller spots, pause between pulses.
2.Turn up settings gradually until desired reaction occurs.
3.Stop treatment as soon as desired reaction for entire area occurs. Aggressive treatments can cause burns and scarring. Less is better for overall outcome.


After each treatment, apply the skin repair solution and wait for 15-30 days before performing the second treatment until the treatment is clean.
