Skin anti-aging—Either in the morning or at the end of the day. Use the light (assuming you have either the Red Rush360 or Platinum device) from about 24”-36” away for 5-10 minutes. (E.g. 5-10 minutes on the whole front of your body and then 5-10 minutes on the whole back of your body.) If you get the Joovv, a more ideal range would be from 24” away for about the same amount of time (but with less broad body coverage area), or from 36” away for several minutes longer (roughly double the time) than you’d use the other lights.
