The DRS Derma Roller 0.25mm is a professional-grade microneedling tool designed for at-home skincare treatments. This derma roller features ultra-fine 0.25mm needles that create microscopic channels in the skin to enhance product absorption and stimulate natural collagen production. As this is a personal hygiene/skincare device, proper sanitization and careful handling is essential. The 0.25mm needle length is considered gentle enough for beginners and suitable for regular use. For best results, the device should be used in conjunction with appropriate skincare serums and products. Always follow proper cleaning protocols before and after each use. Due to the nature of this product, it should not be shared between users.
