The Derma Roller is a microneedling skincare device designed for at-home use. It features fine needles that create micro-channels in the skin to enhance product absorption and stimulate collagen production. The system comes with clear instructions for proper sanitization and application technique. The product packaging includes detailed step-by-step instructions with illustrations showing proper usage technique. Users should first disinfect the roller with medical alcohol, then roll it over the treatment area 4-5 times in multiple directions (horizontal, vertical, and diagonal). The instructions emphasize maintaining consistent speed and pressure during application. For best results, skincare products should be applied immediately after treatment. As this is a personal hygiene device, proper cleaning and sanitization before and after each use is essential.
