The 4 in 1 Skin Care LED Tool uses microcurrent technology to stimulate the muscles and deeper layers of the skin, helping with signs of aging and promoting smooth, healthy skin. The optimal range of LED red light at 660nm helps deeply rejuvenate the skin and improve the appearance and vibrance of the skin. The low-vibration provides a gentle massage, helping decrease the appearance of puffiness and boosting the skin’s natural radiance. The warming wand head helps to increase the absorption of skin care products, reduce redness, and support healthy, glowing skin.
