Frequently Asked Questions

Q: Are these cartridge needles compatible with Dr. Pen models other than the M8 and M7S?

A: No — these Hello Face replacement cartridge needles are designed exclusively for the Dr. Pen M8 and M7S. The arc-edge bayonet design is specific to these models and will not fit other Dr. Pen devices. Please check compatibility before purchasing.

Q: What is the difference between Nano, 3D Nano, 5D, and Round Nano tip types?

A: Each tip type is designed for slightly different application areas and coverage. Nano tips are ultra-fine for delicate zones. 3D Nano and 5D tips offer varying needle configurations for broader coverage. Round Nano tips are suited for curved facial contours. Refer to your device manual or a qualified skincare professional to determine which tip type is best for your needs.

Q: How many cartridges come in a pack, and can I reuse them?

A: These cartridges are available in packs of 10 or 20 pieces. They are designed for single-use only — each cartridge is individually sealed to maintain hygiene and should be disposed of after each session. Reuse is not recommended.

Q: What is the upgraded anti-backflow seal, and why does it matter?

A: The new version of 11-pin, 16-pin, 36-pin, Round Nano & 3D Nano cartridges now features a silicone anti-backflow seal (replacing the previous stainless steel design). This upgrade provides better sealing to prevent any liquid from traveling back into the device, offering improved hygiene and longer-lasting cartridge performance.
