Clinical Protocol: HN20 Transdermal Stamping
Watch the clinical demonstration of the Hydra Needle HN20, highlighting the proper filling of the glass vial and the 90-degree manual stamping technique.

The Physics of Gravity-Assisted Infusion
Traditional droppers waste expensive serums on the dead epidermal surface. The HN20 integrates a sterile glass vial directly above a 20-Pin Titanium Matrix As you stamp the device into the skin, the micro-channels open, and Gravity-Assisted fluid dynamics pull the serum directly down the needles into the active dermis, ensuring 100% product utilization.

FDA-Registered Clinical Safety
Injecting fluids past the skin barrier requires absolute medical sterility. The HN20 is manufactured in an FDA-Registered Facility, holds CE Certification, and is completely EO Sterilized inside its blister pack, guaranteeing a pathogen-free transdermal delivery environment.
Clinical Protocol
Sanitization
Wash face thoroughly. Open the sterile blister pack.
Vial Filling
Unscrew the top and fill the glass vial with pure, watery serum (e.g., Hyaluronic Acid). Screw the needle head back on tightly.
Stamping Technique
Invert the vial so the liquid touches the needles. Press the needles into the skin at a strict 90-degree angle, hold for a split second to allow fluid transfer, and release. Do not drag.
Dispos
The HN20 is a strict single-use device. Discard the entire unit immediately after the session.

FAQs
Please read our FAQs page to find out more.
Q1: How is the HN20 different from an electric Dr. Pen?
A: The HN20 is a manual stamp without a motor. You control the speed and pressure. It is specifically designed to simultaneously dispense serum directly from its attached vial as you stamp.
Q2: Can I reuse the HN20 if I wash it with alcohol?
A: No. Micro-needles become blunt after one use, and blood/biological matter can travel up into the glass vial mechanism. It is a strict single-use clinical device.
Q3: What kind of serums work best in the HN20?
A: You must use low-viscosity (watery) serums. Pure Hyaluronic Acid, Vitamin C serums, and liquid peptides are ideal. Thick creams will clog the needles.
Q4: Should I drag or roll the HN20 on my skin?
A: Never drag or roll. You must "stamp" the device—press it straight down at a 90-degree angle and lift it straight up to prevent jagged micro-tears.
Q5: Is the HN20 painful to use?
A: It is generally less painful than motorized pens because you control the exact pressure, and the needles are ultra-fine titanium, usually set at shallow cosmetic depths.
Q6: Does the liquid flow out automatically?
A: The liquid flows via gravity and the physical tapping motion. As the needles puncture the skin, a tiny vacuum effect helps draw the liquid from the vial into the dermis.
