I’ve had my skin microneedled professionally at the cost of $1000.00 for 5 sessions. I really liked the results so I decided to try doing it myself using the Mr. Pen. I do want to note that you should do a lot of research and watch all the videos you can before doing your own microneedling. You are creating tiny holes in your skin that could easily get infected if you don’t follow proper and sterile procedures. Having said that this product is very easy to use. Since it chargeable you can either use it as a cordless pen or plug it in and use it with power. As a cordless pen I can do my whole face easily without needing to charge it. The kit comes with multiple sizes of sterile packaged needles. I mainly only use two sizes, the 12 pin for my face, and the nano pins for the delicate areas like around my eyes. This set is a good value for beginners and I highly recommend it.
