Key Features

1. Five Cartridge Options for Different Treatment Approaches

Choose from five configurations to match different treatment areas and treatment techniques:

• H12 – 12-pin configuration for more targeted treatment areas
• H24 – 24-pin configuration for balanced coverage across facial areas
• H36 – 36-pin configuration for broader treatment coverage
• Nano-HS – nano-style cartridge for superficial skincare applications
• Nano-HR – nano-style cartridge for gentle surface-level treatments and product application

The different cartridge configurations give professionals more flexibility when building a microneedling or nano-infusion treatment protocol.

H12, H24 & H36 Microneedling Cartridges

The H12, H24, and H36 configurations are designed around different pin counts, allowing professionals to adjust the treatment setup according to the working area and preferred coverage.

H12 – 12-Pin Cartridge

The H12 cartridge provides a lower pin-count configuration for applications where a more targeted treatment pattern is preferred.

Suitable for:

• Smaller facial areas
• Targeted skincare treatments
• Areas requiring greater maneuverability
• Professional microneedling protocols

The 12-pin format can be useful when precision and controlled coverage are more important than treating a larger area quickly.

H24 – 24-Pin Cartridge

The H24 provides a middle-density configuration designed for balanced coverage.

Suitable for:

• General facial treatments
• Cheeks
• Forehead
• Chin
• Other medium-sized treatment areas

It offers a practical option for professionals who want a versatile cartridge configuration for routine microneedling treatments.

H36 – 36-Pin Cartridge

The H36 cartridge features a higher pin count for broader treatment coverage.

Suitable for:

• Larger facial areas
• Body skincare applications where appropriate
• Treatment protocols requiring broader coverage
• Professional aesthetic treatment workflows

The higher pin count provides a denser cartridge configuration, making it useful when treating larger areas.

Nano-HS & Nano-HR Cartridges

The Nano-HS and Nano-HR options are designed for nano-style skincare applications rather than conventional deeper microneedling.

These cartridge types can be incorporated into professional skincare routines where the objective is focused on surface-level product application and cosmetic skin conditioning.

Nano-HS

Nano-HS is a nano-style cartridge option for superficial skincare applications.

It may be selected for:

• Serum application protocols
• Cosmetic skincare treatments
• Surface-level skin conditioning
• Gentle facial treatment routines

Nano-HR

Nano-HR provides another nano-style option for professionals who prefer a different cartridge configuration within their Hydra Pen H3/H5 workflow.

It can be used for:

• Superficial skincare applications
• Cosmetic serum application
• Gentle facial treatments
• Routine professional skincare protocols

Nano cartridges should not be treated as interchangeable with conventional microneedling needle cartridges. Always follow the cartridge and device manufacturer’s intended-use instructions.

Why Keep Replacement Hydra Pen Cartridges on Hand?

For professional treatment environments, replacement cartridges are an important part of maintaining an organized treatment workflow.

Having multiple cartridge configurations available allows practitioners to prepare the appropriate cartridge before each appointment rather than relying on a single cartridge type for every application.

Professional workflow benefits include:

Flexible cartridge selection
Choose H12, H24, H36, Nano-HS, or Nano-HR according to the treatment protocol.

Convenient replacement
Replace the treatment head when required instead of replacing the entire Hydra Pen device.

Treatment-area flexibility
Different pin configurations can be selected for different working areas.

Better treatment preparation
Keeping multiple cartridge types available makes it easier to prepare treatment supplies in advance.

Suitable for professional skincare environments
A practical accessory for estheticians, beauty professionals, salons, spas, and other qualified skincare practitioners using compatible equipment.

Microneedling Cartridge Compatibility

These replacement cartridges are intended for compatible:

• Hydra Pen H3 
• Hydra Pen H5 
• Hello Face Hydra.Pen Dr Pen

Before purchasing, compare your existing cartridge with the product images and confirm that the connection and cartridge format match your device.

Because Hydra Pen models and cartridge systems can vary, device compatibility should always be confirmed before use.

If you are unsure which cartridge you need, contact SalonMachines with a photo of your current device and cartridge.

How to Choose Between H12, H24 and H36

The easiest way to select a cartridge is to consider the treatment area and desired coverage.

Choose H12 when:

You need a lower pin-count configuration for more targeted areas or a precision-oriented treatment setup.

Choose H24 when:

You want a versatile option for routine facial applications with balanced coverage.

Choose H36 when:

You prefer a higher-density cartridge configuration for broader treatment areas.

Choose Nano-HS when:

Your protocol calls for a nano-style, superficial skincare application.

Choose Nano-HR when:

You prefer an alternative nano-style cartridge for gentle cosmetic skincare applications.

Pin count does not determine treatment depth. Treatment depth is controlled by the compatible device and its operating settings, while cartridge configuration primarily changes the needle arrangement and coverage characteristics.

Professional Treatment Applications

Compatible Hydra Pen cartridge systems may be incorporated into professional skincare protocols involving:

• Facial microneedling
• Skin texture-focused treatments
• Fine-line appearance care
• Cosmetic skin rejuvenation routines
• Acne-scar appearance care
• Serum application protocols
• Nano-infusion skincare
• Superficial cosmetic skin conditioning
• Professional facial treatment programs

Actual treatment suitability depends on the practitioner’s training, device settings, cartridge configuration, client condition, and applicable local regulations.

Replacement Cartridge Workflow

A consistent cartridge workflow helps professional practitioners organize treatment preparation.

Step 1 — Confirm Device Compatibility

Confirm that your device is a compatible Hydra Pen H3 or H5 model and that the selected cartridge matches the device.

Step 2 — Select the Cartridge

Choose H12, H24, H36, Nano-HS, or Nano-HR according to the treatment protocol.

Step 3 — Inspect the Cartridge

Before use, check the cartridge housing and needle/nano tip for visible damage, deformation, contamination, or other abnormalities.

Do not use a damaged cartridge.

Step 4 — Prepare the Treatment Area

Follow your professional hygiene and skin-preparation protocol before attaching and using the cartridge.

Step 5 — Attach the Cartridge Correctly

Install the cartridge according to the compatible Hydra Pen device instructions. Do not force the cartridge into place.

Step 6 — Perform the Treatment

Use the device only according to its operating instructions and your professional training.

Step 7 — Dispose of the Used Cartridge

Do not reuse a cartridge intended for single-use treatment. Dispose of used cartridges according to applicable local sharps or regulated-waste requirements.

Hygiene & Safety Considerations

Microneedling involves contact with the skin and, depending on the device settings and cartridge type, may involve penetration of the skin barrier. Proper hygiene and professional technique are therefore essential.

For professional use:

• Use a new cartridge when required by the treatment protocol.
• Never use a cartridge that is damaged or contaminated.
• Do not share a used cartridge between clients.
• Follow applicable infection-control procedures.
• Follow the operating instructions supplied with your Hydra Pen device.
• Use only compatible cartridges.
• Keep unused cartridges in their original packaging until needed.
• Store cartridges in a clean, dry environment.
• Dispose of used cartridges appropriately.
• Do not use microneedling cartridges on compromised or actively irritated skin unless specifically assessed and permitted under an appropriate professional protocol.

Important: These replacement cartridges are accessories for compatible aesthetic devices. They are not a medical treatment, and product results vary according to individual skin condition, treatment protocol, device settings, and practitioner technique.
