The Clinical Configuration Guide
To maximize automatic serum infusion, match the pin count to your fluid viscosity and skin goal:
12-Pin: The optimal configuration for deep hydration and acne scar treatment. Channels are wide enough to allow slightly thicker serums to penetrate deeply into the dermis.
Nano-HR & Nano-HS: Non-penetrating crystalline matrices designed for "BB Glow" and daily essence delivery. They flood the stratum corneum with moisture without causing any bleeding or downtime.

Anti-Clog Tech: Smooth internal reservoir ensures viscous serums flow without interruption.
Adjustable Output: H3/H5 compatible mechanics allow precise liquid output control.
EO Sterilization: Individually sealed to prevent contamination before serum filling.

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.
