Yes, the Hydra Pen H6 is a professional-grade microneedling device and can be used in a spa by a properly trained and licensed practitioner, subject to local regulations. It features adjustable needle depth from 0–2.0 mm, six speed levels, adjustable serum flow, red and blue LED light, and multiple cartridge options. For professional use, always follow strict hygiene procedures and use a new sterile cartridge for each client and each treatment.  

Hi, for microneedling, we recommend using it once every 4–6 weeks to give your skin enough time to recover. If you are using the non-invasive nano needling cartridges, they can usually be used once a week or between microneedling sessions. Please always use a new sterile cartridge each time and avoid using it on irritated skin, active acne, or open wounds.
