The recommended time for one session of full-face Plabeau use is 10 minutes. You can use the Plabeau in one section, or you can gently glide the device back and forth across a whole area. If you choose to use the device in one focused section, depending on your skin type you may feel a warming sensation. If the skin does not feel too hot, you can continue to use the device without issue. Should you feel discomfort, please cease using the device on that section.
