Thanks very much for your question. If you are someone who has no concerning skin conditions (such as acne, rosacea, sensitivity or Post inflammatory Hyperpigmentation), and the device is used correctly, ie not too harshly or aggressively, then it can certainly be used to improve skin cell turn over. However, if you do have any of those skin concerns, and if you are already using very active ingredient that promote skin cell turn over (such as retinol and acids with a low pH), then you may actually cause unnecessary sensitivity, inflammation and in the long run, this can cause pigmentation or more break outs or prolonged sensitivity. So it really comes down to being wise in the treatment of your skin.
