The derma roller is a handheld device equipped with fine needles that create micro-injuries in the skin to stimulate collagen production and improve the absorption of skincare products. It is commonly used for microneedling treatments to reduce the appearance of scars, fine lines, and enlarged pores. The derma roller offers a less intense alternative to professional microneedling devices, making it suitable for at-home maintenance between treatments. Clients benefit from the skin’s improved texture and radiance, as well as the enhanced effectiveness of their skincare products when used in conjunction with a derma roller, making it a versatile tool for long-term skin improvement.
