SkinPen micro-needling resets your skin and is as simple as a 30-minute treatment. SkinPen creates micro-channels (microscopic holes) at a rate of 1600 per second. These wounds stimulate your skin, kicking its healing process into high gear. Best of all, SkinPen doesn’t rely on heat or chemicals, so the results are natural and safe for all skin tones and types. SkinPen targets neck wrinkles and acne scarring. There is little to no downtime."
