Product identity

Bio Pen Q2 Replacement Cartridges (20 Pack) are replacement cartridges for buyers who need the Q2 cartridge path for the Bio Pen Q2 Microneedling Pen (EMS + LED).

Compatible device path

This cartridge listing is for Bio Pen Q2. Confirm the Q2 model name before choosing a cartridge variant or restocking replacements.

Best-fit audience

This page is for Q2 owners or Q2 buyers who need replacement cartridges and want to separate Q2 compatibility from Dr. Pen A10, A6, A9/A8S, M7, or Hydra Pen cartridge families.

Pain or unmet need

The common buying problem is feature confusion. Q2 includes EMS and LED support features, but cartridge selection should still begin with model compatibility, pack size, and variant choice.

Decision variables

• Pack size: 20 replacement cartridges.
• Compatibility gate: confirm the device is Bio Pen Q2.
• Variant options on this listing: 9 Pin, 14 Pin, and 25 Pin.
• Routine planning: choose by Q2 compatibility, intended area, comfort, and product instructions.
• Risk variables: use a fresh compatible cartridge, avoid reuse, and do not use Q2 cartridges with unrelated Dr. Pen models.

Use boundary

This page is compatibility and product-selection guidance. EMS and LED are support features, not guaranteed outcomes. For active acne, infection, keloid history, medication concerns, pregnancy concerns, severe scarring, implanted electronic device concerns, or uncertain skin conditions, speak with a licensed professional before device use.
