Dr. pen is an electric microneedle mesotherapy device. These devices are designed to perform microneedling procedures for mesotherapy, a cosmetic technique that involves the injection of small amounts of customized solutions into the skin. Electric microneedle devices like Dr.pen use fine needles to create micro-injuries on the skin's surface, allowing for the targeted delivery of serums, vitamins, or other beneficial substances into the deeper layers of the skin.

When you are looking for Dr. Pen products, as a beginner, you are likely to be confused about which Dr. Pen model is the best. There are certain factors we recommend you clarify:

1. Speed: Dr. Pen is an electric device, so it can work at different speeds. How fast it works matters, especially for different parts of your face. If you're just starting with Dr. Pen, it's best to choose one with at least three-speed options. This way, you can use it at the speed that's comfortable for you.

2. Depth of Penetration: Dr. Pen can make the needles go deeper or shallower into your skin. The right depth depends on what skin problem you want to fix. Dr. Pens often has a way to change the depth, so you can use it for different things. This is different from traditional derma rollers.

3. Power Source: Some Dr. Pens run on batteries, while others need electricity. Battery-powered ones are more convenient because you can move them around easily. But no matter which type you choose, make sure it's charged or connected to power before you start your skincare routine.

4. Needles in Each Cartridge: Dr. Pen comes with cartridges that hold tiny needles. These needles can be in different configurations, like 12-pin, 16-pin, or 36-pin cartridges. If you're new, you might want to start with fewer needles and work your way up. The 12 and 16-pin cartridges are good for things like fine lines, wrinkles, and redness. The 36-pin cartridges work better for stretch marks, uneven skin color, and large pores.

5. Cartridge Availability: It's important to know that you should only use each cartridge once to keep your skin safe and clean. So, it's crucial that you can easily buy new cartridges when you need them. Make sure they're available so you can keep taking care of your skin effectively.
