The Derma Roller with 1.0mm needle size is a professional-grade microneedling tool featuring stainless steel needles and an ergonomic rose gold handle. This skincare device is designed for at-home microneedling treatments to improve skin texture and promote collagen production. As this is a personal care device that penetrates the skin, proper sterilization and careful usage are essential. The 1.0mm needle length is considered a medium depth that should be used with caution. Users should thoroughly clean and disinfect the roller before and after each use. This device should not be shared with others and should be replaced every few months depending on frequency of use.
