Microneedling with SkinPen can help to improve your skin’s appearance, making it the market standard. SkinPen is different from traditional microneedling derma-rollers that can bend, break or even rust, resulting in possible infection or scarring with reuse. SkinPen uses adjustable length, disposable straight needles to penetrate at a 90-degree angle. This adjustability allows for differences in skin thickness and skin types. The vertical technology allows for extra precision.
