All Dr. Pen Models: The 2026 Complete Guide

If you’re torn between a derma roller and an electric microneedling system, let us make it simple — the electric option is safer, more effective, and far more comfortable to use.

Derma rollers move manually across the skin, and their angled entry creates larger wounds, slowing healing. The rolling motion may even tear the skin, making treatment painful and less precise.

Unlike rollers, electric microneedles work vertically, minimizing skin trauma. They deliver faster, smoother treatments while reducing discomfort and improving healing outcomes.

Needle depth and speed are chip-controlled in electric systems, allowing precise adjustment. They work especially well on delicate or hard-to-reach areas like around the nose, eyes, and nasolabial folds.

All Dr. Pen Models

Over the past decade, Dr. Pen has launched 15 microneedling models — from the original N2 to the latest A11 — each one a step forward in professional skincare technology.

Models like the X5, M7, and M5 may share features, but each has distinct functions. Identifying their differences takes time and careful comparison.

We compare Dr. Pen models across price, default cartridge type and quantity, storage box, max RPM, speed levels, digital screen, needle length adjustment, and included accessories.

We also assess battery type, capacity, usage time, charging methods, body material, weight, and dimensions. This full-spectrum analysis helps you choose the right model for your specific skincare goals.

How to Choose the Right One?

We understand the specs can be overwhelming. That’s why we’re breaking down the key differences to help you find the Dr. Pen model that truly fits your needs.

We’ll start by comparing cartridge types, treatment options, packaging size, motor speed, speed settings, and pen base design. You’ll also learn about needle length adjustment, battery capacity, and included accessories.

Finally, we’ll cover power supply methods, display screen types, cartridge tail structure, ergonomic body design, and build materials — so you can confidently identify the best model for your skincare goals.

Choosing the Default Disposable Cartridges

Each Dr. Pen device supports multiple cartridge types, giving you treatment flexibility. Including every type in the box isn’t practical, so each model ships with two identical cartridges by default.

Default cartridge types vary — some models include 12-pin cartridges, others come with 16 or 18 pins. This lets first-time users try the pen and later choose the cartridge that fits their goals best.

Default Cartridges for Each Model

Pin count affects both sensation and results. More pins spread the pressure, making treatment gentler. Fewer pins penetrate deeper, giving stronger results for targeted work.

Default cartridge	Models
18-pin	A11, M8S, A8S
16-pin	A6S, M8
12-pin	A10, A9, A6, A7, A1, M5, M7, X5, E30, N2

Have the Cartridges Been Upgraded?

Yes. Older models used 0.25 mm needles; newer cartridges use finer 0.18 mm tips for improved comfort, accuracy, and results.

New models also introduce enhanced cartridge structures, such as countercurrent flow designs. These improve needle movement efficiency, helping deliver more consistent microneedling.

What is reverse flow? If serum sits on the needle and the pen touches the skin at an angle, liquid can seep backward into the device — especially when the tip is tilted above the pen body.

Anti-backflow cartridge designs help prevent internal damage. Models with this feature include the A11, A8S, A9, and M8S — ideal if you apply serum directly onto the needle.

Cartridge Tail Designs

The cartridge tail end is the shape of the cartridge base that touches the skin. It affects how the pen delivers serum and how smoothly the treatment feels.

Design	Shape	Models
Flat	Entirely flat edge	A6, A6S, M5, M7, X5, E30, N2, A1, A7
Curved edge	Flat centre with slightly convex edges	M8
Wavy arc	Fully contoured with raised wave-like edges for better serum spread	A11, M8S, A9, A10, A8S

Does It Have MTS & PMU Therapy?

Some Dr. Pen models support both MTS (microneedling) and PMU (permanent makeup). Others are MTS-only, focusing on skin rejuvenation and treatment precision.

Capability	Models
MTS only	A11, M8S, A10, A9, A8S, A6S, M8, A7, X5
MTS and PMU	A6, A1, M5, M7, E30, N2

PMU Tattoo Cartridges

Cartridge	Configuration	Best for
L1	One dot, stainless steel	Fine hair strokes, lip liner, eyeliner
R3	3 dots in a triangle, stainless steel	Eyebrow shading, body tattoo
F3	3 dots in a straight line	Wide lip liner, eyeliner
R5	5 dots — one centre point with 4 evenly spaced around it	Soft eyebrows, lip contour, stem cell pigmentation, pigment removal
F5	5 dots in a straight line	Wider eyeliner, eyebrows, smudged eyeliner, smokey eyes
F7	7 dots in a straight line	Full lips, eyebrows, wide eyeliner
F9	9 dots in two rows — 4 on top, 5 on the bottom	Full lips, eyebrows, wide eyeliner

Most customers prefer MTS-focused devices. Although the M5, M7, A6, and N2 support PMU, they’re mainly used for microneedling, simply because demand for skincare is higher.

If you need both, versatile models like the M5, M7, E30, or N2 handle both treatments effectively.

Does It Come with an Upgraded Storage Box?

Some models include an upgraded storage box, designed to protect the device from contamination while keeping everything organised, clean, and presentable on a countertop.

Currently only the A11, A9, A8S, and M8S ship with this enhanced case. It features a modern design and a thoughtful internal layout that holds the pen and accessories securely in place.

The upgraded box isn’t just about looks — its dedicated compartments provide convenience, cleanliness, and better organisation after each use, which suits both professional and home users.

How Fast Is the Motor?

Motor speed is measured in rotations per minute. The A11 and A6S lead the range at 18,000 RPM, followed by the X5 and M8S at 16,000 and the A8S at 15,500. The M5 sits at the bottom with 12,000.

What’s the Needle Speed Adjustment Range?

Speed adjustment controls how fast the motor drives the cartridge, which affects penetration frequency and how channels form in the skin. Different facial areas may call for different speeds depending on skin thickness and sensitivity.

Most models offer 5 speed levels, some offer 6, and the A7 is infinitely variable. How the speed is displayed varies by model — indicator lights, digital screens, or other interfaces.

Dr. Pen Display Screens

Dr. Pen devices use several speed display types: numeric LCD screens, LED indicators, grid-based levels, and knob-style dials — each a different way to view and adjust speed.

LCD displays show exact numbers. LED lights use colour or blink patterns. Grid systems indicate level by bar count. Knob designs let you turn a physical dial to select a level.

Display design	Models
Non-digital grid display	A10, A9
Direct numerical display	M8, X5, A11, A6S, A8S, M8S
LED light display	A6, M7, A1, E30, M5
Knob design	A7

Does It Have a Holder & Base?

Only the Dr. Pen A11 comes with an inductive holder base. Place the pen on the base and it pauses automatically, then resumes at the same speed when you pick it up.

This keeps treatments smooth and uninterrupted — especially valuable for professional beauticians who need an efficient, hands-free workflow during client sessions.

The A11 also features automatic power management. On the base, the device powers off automatically, conserving energy during treatment breaks. Lift it and it powers straight back on at the previous speed.

What Are the Adjustable Needle Lengths?

Most models offer adjustable needle lengths between 0 and 2.5 mm. The A1 is the exception, allowing adjustment up to 3.0 mm. Thicker skin may call for slightly deeper microneedling.

For more on needle length, see our Dr. Pen cartridge guide. If you need longer needles, the Dr. Pen A1 Wireless and Dr. Pen A1 Wired are your only options.

Is It Rechargeable, and Does It Have a Built-in Battery?

The Dr. Pen A7 is the only model without a built-in battery. It requires a wired power connection, which limits flexibility. For a smoother experience, choose a model with the “W” (wireless) designation.

All other models support both wired and wireless use. Wireless mode offers greater freedom, with no cord clutter and no socket dependency — ideal for at-home treatments or professional use on the go.

What Is the Battery Capacity?

Dr. Pen models range from no internal battery up to 800 mAh. Once fully charged, most run continuously for up to 8 hours, which covers typical treatment sessions.

Model	Battery capacity
Dr. Pen A11	800 mAh
Dr. Pen A9	700 mAh
Dr. Pen A6S	600 mAh
Dr. Pen A6	500 mAh
Dr. Pen A1	500 mAh
Dr. Pen N2	500 mAh
Dr. Pen M8	400 mAh
Dr. Pen E30	400 mAh
Dr. Pen M5	400 mAh
Dr. Pen M7	400 mAh
Dr. Pen X5	400 mAh
Dr. Pen M8S	380 mAh
Dr. Pen A10	380 mAh
Dr. Pen A8S	380 mAh
Dr. Pen A7	None (no internal battery)

Does It Come with a Spare Battery?

The A6S, A6, and A8S include spare batteries, which suits frequent travellers or anyone with limited charging access. The A6S and A6 come with two; the A8S includes one.

Capacities differ: the A6S has 600 mAh, the A6 has 500 mAh, and the A8S has 380 mAh. This affects continuous usage time and overall convenience.

The A6S uses 3D battery technology with 3 drive systems, extending lifespan and stability. The A8S uses 2D technology. Overall, the A6S offers the best performance and durability of the three.

What Is the Cartridge Connector Type?

Connector type may not matter for first-time buyers, but using the wrong cartridge causes compatibility issues. Each model has its own locking mechanism.

There are four connector types: turn-lock with 3 slots, turn-lock with 2 slots, screw type, and built-in bayonet. Each varies in ease of use and stability.

The 3-slot turn-lock is the most practical — easy to attach and secure. The screw type (A7) locks tighter but is less convenient, since installation takes longer.

Model	Cartridge connector type
Dr. Pen A11	Location point (3 slots)
Dr. Pen M8S	Location point (3 slots)
Dr. Pen A9	Location point (3 slots)
Dr. Pen A8S	Location point (3 slots)
Dr. Pen A6S	Location point (3 slots)
Dr. Pen M8	Location point (3 slots)
Dr. Pen A10	Location point (2 slots)
Dr. Pen A6	Location point (2 slots)
Dr. Pen E30	Location point (2 slots)
Dr. Pen A1	Location point (2 slots)
Dr. Pen M5	Location point (2 slots)
Dr. Pen M7	Location point (2 slots)
Dr. Pen X5	Screw type
Dr. Pen A7	Built-in bayonet
Dr. Pen N2	Scale anchor point

Pen Material

Dr. Pen models use either metal or plastic bodies. Metal pens feel more solid and premium, which suits home users treating occasionally.

Plastic models are lighter and better suited to professionals. The reduced weight helps prevent hand fatigue during long procedures, offering more comfort for beauticians and dermatologists.

Model	Pen material
Dr. Pen A11	ABS
Dr. Pen M8S	Aluminium alloy
Dr. Pen A10	Aluminium alloy
Dr. Pen A9	ABS
Dr. Pen A8S	Whole metal
Dr. Pen A6S	Aluminium alloy
Dr. Pen A6	Aluminium alloy
Dr. Pen M8	Aluminium alloy
Dr. Pen E30	Aluminium alloy
Dr. Pen A7	Aluminium alloy & plastic
Dr. Pen A1	Aluminium alloy & silicone
Dr. Pen M5	Aluminium alloy
Dr. Pen M7	Aluminium alloy
Dr. Pen X5	Aluminium alloy
Dr. Pen N2	ABS & plastic

Final Thoughts

When choosing a Dr. Pen model, look for the features that match your needs — spare batteries, an upgraded storage box, needle length range, dual MTS & PMU capability, budget, or even a specific colour (purple is X5 only).

If you’d rather not spend time researching, here’s our short version. Whether you’re a first-time user, a professional beautician, or someone who just wants convenience, these four recommendations should point you to the right device.

1. Where possible, choose a wireless model over a wired one. Untethered use gives you more flexibility and mobility during treatments, with no cords and no need for a nearby outlet.
2. Consider the Dr. Pen A6S for travel. It comes with two removable batteries and, more importantly, a 3D technology power system for durability and long service life — ideal for frequent users on the go.
3. Beauticians may find the A11 the best fit. It offers the largest battery capacity and an automatic sensing holder that switches the device on when you pick it up and pauses it when you set it down. Its memory function recalls the settings from your last treatment.
4. For beginners trying microneedling for the first time, the M8 is the best choice — our best-selling and most popular model, and a reliable place to start.
