The DRS Derma Roller 0.5mm is a professional-grade microneedling device featuring a sleek gold-plated handle design and 540 titanium micro-needles. This at-home skincare tool is designed to improve product absorption and stimulate collagen production for healthier, more radiant skin. Since this is a personal care device used for microneedling treatments, it should be properly sanitized before and after each use. The 0.5mm needle length is considered suitable for at-home use but should still be used with caution. The device appears to come in a protective case for safe storage. As with all microneedling tools, users should follow proper hygiene protocols and discontinue use if skin irritation occurs.
