otMicroneedling and derma rolling are similar in concept but differ in their application. Microneedling involves the use of a professional device with fine needles to create controlled micro-injuries, while derma rolling uses a handheld device with a roller covered in needles. Microneedling is typically performed by a skincare professional and offers more precise control and customization, while derma rolling is a more affordable at-home option but may provide less targeted results.
