The Nu-Derm System penetrates the skin’s surface to transform the skin’s appearance and help correct the damage within…revealing healthy, younger-looking skin. Skin aging is a natural process, but daily sun exposure can contribute to premature aging, slowing down the turnover of skin cells between healthy new cells and old damaged cells. Nu-Derm is ideal if you have age spots, rough skin, erythema(redness), sallowness(yellowish complexion), and hyperpigmentation(discoloration).
