Microneedling Pen Guide
Dr. Pen M8S vs A11: Which Microneedling Pen Should You Choose?
Both pens share the same adjustable-depth microneedling platform and the same needle cartridges. The real difference comes down to power flexibility — cordless simplicity versus wired-or-wireless convenience.
Quick Answer
Choose the Dr. Pen M8S if you want a compact, fully cordless pen — it's lighter, simpler to store, and charges over USB-C. It's a great fit for a personal at-home routine.
Choose the Dr. Pen A11 Ultima Pro if you'd like the option to plug in for longer or more frequent sessions. Its dual-power design (wired or wireless) and inductive charging stand mean you're never waiting on a battery — equally useful at home or for treating multiple people in a day.

Dr. Pen M8S
A cordless, USB-C rechargeable pen that fits neatly into a personal skincare routine. It's compact, easy to travel with, and doesn't require a charging base to operate.
Dr. Pen A11 Ultima Pro
Works just as well for a personal routine, with the added option to plug in for longer sessions. The wired mode removes any concern about running out of battery mid-treatment, and the inductive stand keeps it charged and ready between uses.
Motor and Speed Settings
Both the M8S and A11 give you 6 adjustable speed levels, so switching between a gentler setting for sensitive areas and a faster setting for firmer skin works the same way on either pen. Lower speeds are generally better suited to thinner or more sensitive areas, while higher speeds are more efficient for fleshier areas like the cheeks and body. Neither pen has a meaningful advantage in day-to-day treatment feel — the real distinction between the two models is in how power is delivered, not how the motor performs.
Needle Depth and Cartridges
Depth adjustment is nearly identical: the M8S adjusts from 0.25mm to 2.5mm, and the A11 adjusts from 0mm to 2.5mm, giving both pens a practical range for everything from light nanoneedling to deeper treatment areas. Depth should always be selected based on the treatment area and your comfort level, starting shallow and building up gradually.
The M8S and A11 use the same needle cartridge system, available in 12-pin, 18-pin, 24-pin, 36-pin, 42-pin, and nano options. This means you can stock a single set of cartridges and use them across either pen, which simplifies reordering if you ever own or switch between both models.
Power, Charging, and Workflow
This is where the two pens diverge most. The M8S is cordless only — it charges over USB-C and runs entirely on its internal battery, which is straightforward for a single daily or weekly routine at home.
The A11 Ultima Pro offers dual power: a wired mode with a 2-meter cord for uninterrupted sessions, or a wireless mode rated for 3–4 hours per charge. It also comes with an inductive charging stand that automatically stops the pen when it's set down and restarts it when picked back up — handy whether you're moving between treatment areas at home or fitting in several sessions in the same day.
Design, Display, and Ergonomics
Both pens use an ergonomic, anti-slip body shape designed for comfortable handling. The A11 steps up with a larger LED control screen for clearer visibility of speed and settings during treatment, while the M8S keeps a simpler, more compact display — a matter of preference rather than a limitation for home use.
