You may sometimes notice tanning after treatment. The cause of this tan is the exposure to infrared light/warmth. This effect is harmless and fades away by itself after a number of weeks and sometimes after a few months. Postpone the treatment until the tan has disappeared.
To prevent tanning, resume treatment in a lower mode (only for HP3641) and/or increase the distance between the body and infrared lamp and/or reduce the treatment time.
