The GTS Derma Roller is a professional microneedling device featuring 192 titanium needles at 1.00mm length. This derma roller is designed for advanced skin treatments, helping improve skin texture and appearance through controlled micro-injuries that stimulate natural collagen production. Since this is a personal care/cosmetic device that penetrates the skin, proper sterilization before and after each use is essential. The 1.00mm needle length is considered a professional grade and should be used with caution. It's recommended to consult with a skincare professional before using this needle length, as improper use could cause injury. The device comes in sterile packaging with a protective case for safe storage between treatments.
