I am not new to Dr Pen products and was happy to get to try the newer A10 version. I like how you can customise both the length of the pins and its operating speed to your preference. Having a rechargeable battery also allows for the ease of use as there isn’t any wire to get in the way when you’re gliding the pen across your face. This is great for someone who is a relative newbie to microneedling but wants to invest in a device that will last a long time and offers value for money (especially since it comes with a selection of cartridges).
