This is my first time using a micro needling pen and have to admit I was a bit nervous. I thought it would be painful.
It isnt at all! After using it for 2 weeks I am starting to see results.
So I started using the microneedle pen in up and down light strokes on my right cheek and I actually took a photo and uploaded to show you that I still have some red on the left cheek but on the right cheek the redness is dissipating quicker. (The green arrow.)

I like the fact that you can leave it plugged in and use it with the cord method or you can actually use it with the built-in battery and charge it up and remove it for use. Also the cartridges are easy to snap and turn onto the pen itself. Getting the cartridge off is easy as well, just follow the directions in the information booklet.
I do have sensitive skin but I would still recommend this to someone who has sensitive skin, has fine lines or discolorations on the face or other parts of the body that they would like to get rid of (or lessen the appearance of) this pen is also great to aid in anti-aging. I definitely feel like it's making my skin look younger and I'm fixing to proceed using the pen on the other cheek to see if f I get similar results on that side of my face.

When I compared the price of this microneedling pen to others I realized what a good value it is as far as price, I like the sleek styling and it is easy to grip. I also appreciate the light indicator window which lets me know when it's ready to go or if it needs charging. It does change from red to green when it's ready (great to know if you're going to use the wireless method).
Everything is included that you need in the box with easy to read and follow diagrams and instructions.
Another thing to keep in mind is that since this does penetrate the first layer of skin, I would not recommend wearing makeup on the days that you use your microneedling pen.
