The ZGTS Derma Roller is a professional-grade microneedling device featuring 0.50mm needles. This skincare tool is designed for at-home use to help improve skin texture, reduce fine lines, and enhance product absorption through controlled micro-injuries to the skin surface. Since this is a personal skincare/hygiene device, it should be properly sanitized before and after each use. The 0.50mm needle length is considered suitable for at-home use but should still be used with caution. The gold-tinted roller head and ergonomic handle design allow for comfortable and precise application. As with any microneedling device, results typically require consistent use over time and proper aftercare protocols should be followed.
