The Dr.Pen Hydra Needle collection features the HN20 and HN30 — refillable derma stamps designed to deliver serums directly into the skin through 20 or 30 fine titanium pins. Unlike motorized microneedling pens, Hydra Needles work with gentle manual pressure, making them an easy addition to any at-home skincare routine.

Each stamp includes a refillable vial that holds your preferred serum, essence, or toner, allowing simultaneous micro-channeling and product infusion in a single step. Choose between the HN20 for targeted areas or the HN30 for broader coverage.
