Dr. Pen M7 vs. M8: A Comprehensive Comparison for Choosing the Right Model

The Dr. Pen microneedling pen series is known for being a trusted tool for skin rejuvenation, cosmetic treatments, and microneedling. Among the various models, the Dr. Pen M7 and Dr. Pen M8 are two very popular models, with the M7 being more popular in the European region and the M8 being more popular in North America, according to our user feedback data.

Both are designed for users who are looking to achieve professional results at home or in the clinic. While they appear similar on the surface, and since the model names differ by only one number, many would assume that the M8 is an upgrade from the M7. The M8 is not an upgrade from the M7, and they have distinct differences that cater to different treatment needs and user preferences. In this comparison, we will take an in-depth look at these models, looking at their specifications, usability, and potential applications to help you make an informed decision and choose the model that is best for you.

1. Microneedling and Treatment Applications

One of the main differences between the Dr. Pen M7 and M8 is their treatment capabilities. While both devices are designed for microneedling, they differ slightly in terms of functionality.

Dr. Pen M8 is designed for the Microneedling Treatment System (MTS) and is ideal for skin rejuvenation, acne scar treatment, wrinkle reduction, and skin texture improvement. If your primary goal is to target fine lines, acne scars, or general skin renewal, the M8 offers dedicated microneedling performance without the need for additional cosmetic applications.

In comparison, the M7 offers greater versatility for both MTS and Permanent Makeup (PMU). This makes it a better choice for those who want a device that can not only treat skin issues but also be used for cosmetic applications such as eyebrow tattoos, eyeliner, and lip color. The M7 is a more comprehensive choice for cosmetic professionals who perform PMUs at the same time as microneedling treatments. The M8 has all the features of the M7, but the M7 has PMU features that the M8 does not.

Conclusion: If you are looking for a device purely for skin rejuvenation, the M8 is tailor-made for that. However, if you need the flexibility to switch between microneedling and permanent makeup, the M7 offers a wider range of features.

2. Syringes and Needle Configuration

Microneedling treatments are largely dependent on the type and configuration of the syringe. Both the M7 and M8 come with disposable syringes, but the number and configuration of needles differ.

The biggest difference between their needles is that the M8 has a thinner needle of only 0.18mm, which can lead to better treatment results, less trauma and faster recovery. The M7 has a needle diameter of 0.25mm.

The M8 comes with a 16-needle disposable syringe, which provides more needles per syringe. This means that the treatment can cover more skin surface area, which may be ideal for larger areas of the face or body. The thinner syringe also makes the M8 the first choice for more precise and delicate treatments, ensuring minimal discomfort and faster healing time.

You can also buy other needle sizes of the M8 in our store, such as 11pin, 16pin, 24pin, 36pin, 42pin, NANO S, NANO R, NANO 3D, NANO R, NANO 5D.

On the other hand, the M7 comes with a 12-needle disposable syringe. While it has fewer needles than the M8, the 12-needle configuration is the industry standard and still provides effective results for microneedling. The lower needle count also means that this model is better suited for smaller areas that require more delicate work, or for those who prefer a slightly less aggressive treatment process.

Conclusion: The 16-needle cartridge of the M8 is an advantage if you are treating larger areas or seeking the finest precision. However, for a more controlled and potentially less intensive treatment session, the 12-needle cartridge of the M7 may be preferable. But frankly, since they can all have other types of adaptable needles.

3. Speed and Power

The speed and rotational power (RPM) of a microneedling device are key factors that affect its performance. Faster speeds allow for faster treatments and better needle penetration, improving overall results.

Dr. Pen M8 runs at up to 15,000 RPM in six adjustable speed levels, allowing for customized treatments based on user preference and skin type. The higher RPM makes it particularly effective for tougher skin areas or clients with thicker skin that require deeper penetration.

The M7 offers slightly lower power, with a maximum of 14,000 RPM and five adjustable speed levels. While this product is still powerful enough for most microneedling treatments, the reduced RPM may be better suited for users with sensitive skin or those who prefer a more controlled, less intense treatment.

Conclusion: If you’re looking for a more powerful device that allows for better customization of speed and treatment intensity, the M8 is a better choice. However, the M7 still provides plenty of power for most treatments, making it a great choice for users with more sensitive skin.

4. Design and Usability

When using a microneedling device, design plays a vital role in the user experience, especially for users who plan to use the device frequently.

The M8 is designed with a compact, travel-friendly size, making it convenient for users who want to take the device with them. In addition, it features an LED screen with a digital display, allowing users to easily monitor and adjust speed settings during treatment. The three-slot cartridge connector is an upgrade from the previous design, ensuring greater stability and precision during treatment.

The M7 was also designed with portability in mind, making it equally suitable for travel or home use. However, unlike the M8, it does not have a visible LED screen. Instead, it relies on indicator lights to display speed settings, which may not provide precise control, but is still effective. The M7 uses a two-slot cartridge connector, which, while not as advanced as the M8, still provides a secure cartridge connection.

Here we would like to add some clarification on what exactly does a three-slot design mean vs. a 2-slot design? Three slots refer to the three-slot design where the pointer tip contacts the pen, and two slots refer to the two-slot design. Obviously, three slots are more stable than two slots.

Conclusion: For those who prioritize modern design and ease of use, especially when it comes to monitoring speed settings, the M8’s digital display has a clear advantage. On the other hand, for users who don’t mind a more basic interface, the M7 is still a good choice.

5. Power and Battery Life

Both Dr. Pen M7 and M8 come with built-in rechargeable batteries, providing users with wireless convenience. However, there are some notable differences.

The M8’s 400mAh built-in battery provides wireless and wired operation, providing flexibility based on the user’s preference. The convenience of switching between wireless and wired modes ensures uninterrupted treatment, especially during longer sessions. While the battery life is sufficient for most users, it does not come with an extra battery, which means you will need to recharge once the power is exhausted.

Like the M8, the M7 also comes with a 400mAh internal battery for both wireless and wired operation. However, it also does not come with an additional battery, so if the battery is depleted, it will need to be stopped to recharge. The key difference is that due to the M7’s lower RPM, its power consumption may be slightly lower, which may give it a slight advantage in battery efficiency during treatments.

Conclusion: Both models offer wireless convenience and flexibility. If battery life is a primary concern, the M7’s slightly lower power consumption may make it slightly more efficient, but the difference is small.

6. Which Model Should You Choose?

Choosing between the Dr. Pen M7 and M8 depends largely on your specific needs and preferences. Here is a simple summary to guide your decision:

Choose the Dr. Pen M8 if:
You prioritize or only want to use it for skin rejuvenation and microneedling (MTS).
You want a device with more power (15,000 RPM) and six speeds for greater customization.
You prefer a device with an LED screen and digital display for easier monitoring.
You want a thinner needle barrel for more precise treatment.

You need a reliable, portable device that can be used for both beauty and treatment.

Final Thoughts

Based on our industry experience, the most important consideration when choosing between the M7 and M8 is whether you need a multi-functional microneedling pen or a single-function one.

The Dr. Pen M8 is a more advanced choice for users seeking premium microneedling performance, while the M7 offers greater versatility with its PMU feature.

Do you want to experience a thinner needle? M8 has a thinner needle, which means less pain and faster recovery, but the effect is not as significant as M7.
