Liquid-Containment Flow Dynamics
Gravity-fed auto-infusion requires perfect pressure. Fake or reused cartridges suffer from micro-clogging. The official H3/H5 cartridges are engineered with precise Liquid-Containment Flow Dynamics, ensuring that even viscous serums like Hyaluronic Acid flow seamlessly down the needles directly into the dermis without spilling or backing up.

The Danger of Serum Residue
You cannot wash out a Hydra Pen cartridge. Microscopic serum proteins and blood remain trapped inside the internal containment reservoir after a single use. At room temperature, this becomes a massive breeding ground for staph bacteria within 12 hours. Strict single-use protocol is non-negotiable.
Clinical Protocol & Disposal
Filling
Inject your chosen serum into the sterile cartridge reservoir.
Installation
Lock onto the H3/H5 pen and adjust the output level.
Execution
Glide over the skin; the needles will automatically dispense the serum into the micro-channels.
Disposal
Dispose of the entire cartridge immediately. Do not attempt to rinse and save leftover serum.

FAQs
Please read our FAQs page to find out more.
Q1: Why can't I rinse the H3 cartridge and reuse it?
A: Microscopic serum proteins and biological matter get permanently trapped inside the fluid reservoir. Reusing it will inject stagnant, bacteria-ridden fluid into your skin.
Q2: What serums are best to use in these cartridges?
A: Low-viscosity serums like pure Hyaluronic Acid, Vitamin C, and liquid peptides are ideal. Extremely thick creams will clog the flow mechanism.
Q3: Does the H3 cartridge fit the H2?
A: No. The H3 and H5 cartridges feature an updated locking and fluid-dispensing mechanism that is not backward compatible with the older H2 model.
Q4: Which needle count should I use for BB Glow?
A: You should exclusively use the Nano-HR or Nano-HS cartridges for BB Glow. They deliver the pigment into the very top layer of the skin without causing bleeding.
Q5: How do I control how much liquid comes out?
A: The Hydra Pen H3/H5 devices have a built-in customizable output dial that adjusts the pressure applied to the cartridge reservoir, controlling the flow rate.
Q6: Will the needles bend if I press too hard?
A: The surgical titanium needles are highly resilient, but pressing too hard disrupts the fluid dynamics and causes scratching. Let the automatic mechanism do the work.
