Product Details
42-Pin Replacement Microneedling Cartridges
These replacement cartridges contain 42 needles across the treatment face and are designed for the compatible Dr Pen A1-C two-stud bayonet connection.A microneedling cartridge is a single-use sharp, not a reusable accessory.Once a cartridge has entered the skin, it may carry blood, tissue and microorganisms, while the needle tips may also be affected by use.Cleaning the outside of a used cartridge does not make it suitable for reuse.Use a new, compatible, sealed cartridge for every treatment or client. Never reuse or share cartridges.What Does 42-Pin Mean?
“42-pin” describes the number of needles across the cartridge treatment face.It does not determine the correct treatment depth and does not mean that this cartridge is automatically better, gentler or more effective for every skin concern.For needle counts, depths and how to choose, see the Ultimate Microneedling Guide.Compatibility

What Goes on Your Skin Matters
Microneedling temporarily disrupts the skin barrier. Products used during a procedure therefore need to be chosen carefully.Do not assume that an ordinary cosmetic serum, pigmentation serum, acid, retinoid, raw cosmetic ingredient or DIY mixture is appropriate for use during microneedling.Our Hydrating Glide Serum is specifically formulated for microneedling and provides hydration and slip during treatment. For a pigmentation-focused treatment, our Microneedling Pigmentation Serum (4% Tranexamic Acid + Hyaluronic Acid) is formulated for the job. Do not use both serums in the same session.After microneedling, keep skincare simple and focus on hydration and barrier support with our Ceramide Barrier Support Cream.Need everything in one box?

Learn Before You Microneedle
Buying a cartridge does not mean every treatment, depth or skin condition is appropriate for home microneedling.Treatment depth, skin condition, hygiene, technique, device settings and professional scope all matter.Microneedling for Pigmentation?
If pigmentation, melasma or uneven skin tone is one of your main microneedling concerns, look at our Tranexamic Acid Microneedling Serum — developed as a pigmentation-focused option for use alongside microneedling.

One fresh cartridge. Every treatment.
42-pin, individually sealed replacement cartridges for the Dr Pen A1-C. A microneedling cartridge is a single-use sharp — a new, sealed one for every treatment isn't an upsell, it's the whole point of doing this safely.
The unglamorous part that quietly keeps microneedling clean — done properly, never cut short.

The Compatibility
Made for the Dr Pen A1-C two-stud bayonet connection. Not for Hydra Pen or M8S 16-pin systems — always check your connector against the images before you order.

Individually sealed, single-use only. Once a cartridge touches skin it can't be cleaned for reuse — a fresh one every treatment, then disposed of as a sharp.
Sealed · single-useThe Configuration
42 needles across the treatment face. (Pin count describes the cartridge — it doesn't set your depth or make it "better" for every concern.)

You've got your A1-C — a fresh cartridge is just one part of the session. Keep the two consumables that actually go on your skin stocked up too.
