A derma roller is a device that is outfitted with needles and looks painful, but it’s not! Rolling the derma roller over your face three times per week with light pressure literally creates small holes in skin. Why? To allow ingredients to better penetrate and improve the look and feel of skin over time, as well as to stimulate collagen and healing to the affected area/scar.
