The Dr. Pen Hydra Needle HN20 is a manual 20-pin microneedling derma stamp with an integrated 5 mL glass serum vial. It combines a stamping head and topical serum application in one compact skincare tool, without a motor, battery, charging cable, or electronic speed controls.
Available in multiple fixed needle-length options, the HN20 is designed for users looking for a straightforward Hydra Needle derma stamp rather than an electric microneedling pen.
Unlike an electronic microneedling pen, the HN20 uses a simple manual stamping design. Its compact construction combines the needle head and serum vial in one unit, making it easy to understand, carry, and integrate into a cosmetic skincare routine.
The Dr. Pen HN20 is available in different fixed needle lengths. Unlike adjustable microneedling pens, the needle length is determined by the HN20 version selected at the time of purchase.
| 0.25 mm | Fixed 0.25 mm HN20 configuration. |
|---|---|
| 0.5 mm | Fixed 0.5 mm HN20 configuration. |
| 0.6 mm | Fixed 0.6 mm HN20 configuration. |
| 1.0 mm | Fixed 1.0 mm HN20 configuration. |
| 1.5 mm | Fixed 1.5 mm HN20 configuration. |
Always check the selected variant before ordering. Follow the supplied product instructions and seek professional guidance if you are unsure which needle length is appropriate for you.

The HN20 combines a manual 20-pin stamping head with a refillable serum vial. During use, the tool is manually pressed against the intended cosmetic skincare area while the vial holds a compatible topical product.
Because the HN20 is manually operated, it does not use adjustable speed levels or electronically controlled needle movement.
