What Details Do Dr. Pen A6 & M7 Have in Common?
When it comes to specifics, there’s a lot to explore about their similarities in needle cartridges type, power source modes, adjustable needle length or depth, and the materials used in their exteriors.
Needle Cartridges Type
Both devices boast a comprehensive array of 16 needle cartridges, encompassing a diverse range such as 9-pin, 12-pin, 24-pin, 36-pin, and 42-pin needle cartridges. Additionally, they offer specialized cartridges like nano s, nano 3d, nano 5d, and nano r, all falling under the sophisticated Microneedle Therapy System (MTS). Furthermore, both devices feature a versatile selection of 7 Permanent Makeup Needle (PMU) cartridges, each with unique designations such as L1, R3, F3, R5, F5, F7, and F9. However, it’s pertinent to note that PMU cartridges might not resonate as favorably with consumers when it comes to Dr. Pen, possibly due to the existence of more advanced alternatives in the market.
Wireless & Wired Mode
The devices present users with the flexibility to choose between wireless and wired models, catering to diverse preferences. In the realm of wireless convenience, models A6-W and M7-W take center stage, where the appended “W” denotes the wireless functionality. On the other end of the spectrum, the wired counterparts include A6-C and M7-C, with “C” symbolizing charge. The A6 and M7 wired models necessitate a USB cable connection for power, revealing a nuanced consideration for convenience—requiring users to be in proximity to a power source, thus compromising a degree of portability.


Einstellbare Nadeltiefe
An outstanding feature shared by both devices is their MTS needle cartridges, providing users with the remarkable flexibility to finely adjust the needle depth across an extensive range from 0 to 2.5mm. Exploring the nuances of needle length reveals its pivotal role in determining the depth of penetration into the skin.
For example, a 1mm needle length signifies a penetration of approximately 0.75mm, targeting the upper layers of the dermis. When tackling acne scars, optimal needle lengths ranging from 1.5mm to 2mm prove effective in smoothing out these imperfections. Addressing concerns like enlarged pores calls for a strategic choice of a 0.5mm needle, ensuring positive outcomes without causing bleeding.
In the realm of electric micro-needling characterized by vertical movements, these devices minimize trauma, offering a notably gentler experience compared to traditional roller devices.
The meticulous control over speed and depth, facilitated by an embedded chip, further elevates the user experience, with faster speeds correlating to minimized skin trauma. This intricate decision-making process in selecting the right combination of needle length and speed underscores the devices’ unwavering commitment to addressing specific skincare needs.
Stift Material
Both feature a sleek aluminum alloy body, emanating a luxurious metallic ambiance. Furthermore, each is accompanied by a storage plastic box for added convenience.
Letzter Gedanke
The most significant distinction between A6 and M7 lies in the battery features, making Dr. Stift A6 the optimal choice for frequent travelers. If budget considerations come into play, Dr. Pen M7 is a viable option. However, we highly recommend opting for the wireless version, as the convenience of wireless operation becomes evident only after experiencing it firsthand.
