Replacement Needle and Nano Heads for A1 Microneedling Pens
This listing is for A1 replacement cartridges only. The microneedling pen is sold separately. Choose from five needle counts or three nano tip styles for your existing A1 pen. These disposable consumables let you replace the contact head between sessions without replacing the device.
Key Features
- A1 fit: Replacement heads for the Dr. Pen A1 model shown in the product images. Do not assume they fit other pen models.
- Five needle options: 9, 12, 24, 36 and 42 pins.
- Three nano options: 3D Nano, 5D Nano and Round Nano, with different contact-face designs.
- Single-use design: Use a new cartridge for each person and each session.
- Visible construction: The transparent blue-purple housing shows the internal spring and drive shaft.
Suitable For
For A1 pen owners and trained skincare practitioners restocking replacement heads. Needle cartridges and nano tips are different options, not interchangeable names for the same tip. Select the head for the intended procedure rather than assuming a higher pin count gives better results.
How to Use
- Switch off the A1 pen before fitting or removing a cartridge.
- Open an intact individual packet immediately before use. Do not use a cartridge if its packet is open or damaged.
- Fit the cartridge according to the A1 pen instructions. Speed and needle projection are controlled by the pen, not by the cartridge alone.
- Use the selected head only for its intended purpose. Dispose of it after the session; do not share or reuse it.

Frequently Asked Questions
Does this listing include the microneedling pen?
No. This listing is for replacement cartridges only. The A1 pen is sold separately.
Which cartridge options can I choose?
The selectable options are 9, 12, 24, 36 and 42 pins, plus 3D Nano, 5D Nano and Round Nano. The reference chart includes other examples that are not selectable on this listing.
Will these fit every Dr. Pen model?
No universal fit is claimed. This listing specifies A1. Check the model and connector before ordering rather than choosing by appearance alone.
How are the nano options different?
The product photos show a smaller square contact face for 3D Nano, a larger square face for 5D Nano, and a circular face for Round Nano. These names describe tip options, not needle depths or guaranteed results.
What needle size should I use?
Pin count and needle depth are different. The selected option determines the head configuration, while the compatible pen controls needle projection. A trained practitioner should select settings for the individual procedure.
What is an A1 microneedling pen used for?
It is a powered device used in skincare procedures focused on concerns such as visible fine lines, uneven texture, pores, scars, stretch marks and pigmentation. This listing supplies replacement heads, not the device, and does not promise correction of those concerns.
How often should I use the pen?
There is no single schedule for every person or procedure. Follow the device instructions and a qualified practitioner's guidance rather than applying a fixed interval to all skin conditions.
Can I wash and reuse a cartridge?
No. These are disposable cartridges. Use a fresh cartridge for each person and each session.
How do I check an authentication code?
If the supplied packaging has an authentication label, scratch to reveal the full QR code and number, then follow the verification instructions on that packaging. A product photo alone does not verify authenticity.
Do the different tips guarantee specific skin or hair results?
No. Pin count does not guarantee scar reduction, acne clearing, skin lightening or eyelash and eyebrow growth. Nano tips are not a promise of painless use or a substitute for professional assessment.
How long will it take to receive my order?
All orders are processed within 3–7 business days (most in-stock items are typically dispatched within 1–3 business days). Estimated delivery times vary by shipping method:
- Standard Shipping: 12–20 days (taxes included on most routes — check at checkout)
- Expedited Shipping: 7–15 days (DHL, UPS, FedEx, TNT, ARAMEX) — ⚠️ (you pay import taxes)
- Sea or Rail Shipping: 40–60 days ocean transit + 5–10 days local delivery (taxes included)
- Air Shipping: 5–8 days air transit + 5–10 days local delivery (taxes included on most routes — check at checkout)
Your shipping method is marked at checkout: "(taxes included)" means the price you pay is final — sit back and wait for delivery, nothing else to handle. "(you pay import taxes)" means any import taxes charged by your country on arrival are yours to pay — these are collected by your country's customs, not by us.
⚠️ Please double-check your shipping method before ordering. If it says "(you pay import taxes)", those charges are your responsibility — we can't accept disputes or refund requests for import taxes on methods that don't include them.
How to track my order?
Once your order is dispatched, you'll receive a tracking number by email. You can track it anytime on our tracking page: 17track.net — just enter your tracking number there.
- If your order was just dispatched, it may take 1–2 days for tracking information to show up in the system.
- For Sea or Rail Shipping, tracking may pause during the ocean leg — usually 40–60 days — and resumes once the parcel reaches your local courier.
- If tracking hasn't updated for a while, or you can't find your tracking number, contact us at info@itechaesthetics.com — we'll check with the courier and push for an update.
