I have been researching micro-needling for some time and was so excited when this Dr. Pen Ultima M8 Microneedling Pen Professional Kit crossed my path. It was the exact one I wanted! It is a well-known brand and they have some short videos on YT showing how to use it. I have always used a Derma roller on my face, but started to feel that it was too aggressive quite a while back, so I stopped.
This Dr. Pen Ultima M8 kit comes well packaged, with all of the needle cartridges individually wrapped and sanitary. This brand has been around a very long time and there is much to be learned from them. They have a great website, a number to call to speak with someone if you have any questions or concerns.
It comes with a small instruction manual with the basic information and important information on needle depths and speeds for most needs. I found videos helped fill in the gaps, and gave me a feel of what to expect by seeing and hearing others' experiences. Dr Pen has a great YT channel, but  I've learned a lot from watching PENN.SMITH.SKINCARE on YT, as well.
I started with a fairly low setting for my first try, and it went well. To me, it is much easier and less painful than dermarolling. You have much more control, as the machine really does all of the work very quickly. I did not overdo it, just to see how my skin reacts over the next several days. I used a fairly simple hyaluronic acid serum while micro-needling, waited an hour, rinsed my face very well with just water, and reapplied the serum. I did not put anything else on my face for 24 hours. I had some redness and a bit of heat, but nothing like with Derma rolling. It was pretty much gone by the next day.
I really like this micro-needling pen! It's very easy to use, it comes with most everything you need, and it would make a perfect gift for someone seeking their very first one. I would absolutely recommend it!

I watched videos for a couple weeks on how to use this since there weren’t instructions included before I took the leap. I went over my whole face with a needle length of .5 to begin with and at 4 for the speed. I then went back over my problem areas with the needle length at .75 and a speed of 5. I was really into the moment so I went back over one more time with the needle at 1 and the fastest speed of 6. I definitely recommend the fastest speed. My face was red for about 24 hours. Swollen for about 48. After about 3 days I got to see my glorious results. My pores look tighter, my sebaceous hyperplasia isn’t as pronounced. It definitely made my skin look better. I’m sold. I can only imagine how good my skin will look after continuous use.

I have tried a number of micro-needling devices and in my opinion the Dr. Pen M8 is one of if not the best.

It’s very easy to use and the controls allow you to adjust the speed etc. This kit comes with several needles cartridges. The lower the number the more intense the procedure. So lower number needles are better for scarring and other skin issues. That said, I would suggest watching videos and reading literature on how to do it and going slow when starting micro-needling as the kit does not come with detailed instructions.

There are marked variations on price on this unit depending on where you buy it, so it’s a good idea to comparison shop. The Dr. Pen M8 is not cheap, but if you have good results from it, it’s well worth it.

Absolutely love everything about it. It does an amazing job, high quality needles, holds a charge for a looooong time, and much smaller than most other pens that tend to be a bit bulky for my hand. Hopefully this lasts forever cause it's a lifesaver

First time using a needling pen, was easy to use! So far so good. I’m just glad I don’t have to walk out of a clinic all red ever again! Do recommend ensuring your skin is sanitized before and using gloves during treatment, less is more, don't feel like you need to go straight to 2.5mm for results. If you haven't needled before definitely look up some tutorials these are professional pens and need to be used as so. I did not use numbing cream and did not experience any unbearable pain and only very mild discomfort.

But it appears to be a good pen. Pretty straight forward, I chose this pen because the needle length is adjustable on the pen instead of having to buy different length cartridges.

I used it for the first time anD **** THAT **** HURTS. Its tolerable, but it does sting for a few days after.

[Update] I learned that applying a hyaluronic acid sheet mask immediately after needling for at least 15 minutes will significantly reduce the recovery time before your skin feels more normal and less red. I can vouch for that.

I had much better success with this pen than the dermaroller. I am far more careful on how much pressure I am applying. Just be careful what you put on your skin right after. A couple of my serums that are usually pretty gentle, stung quite a bit when I applied them right after.

I really like this Dr Pen microneedle device. It comes almost fully charged and doesn't take much longer to become charged the rest of the way. It's actually pretty easy to use. I haven't had any issues with it, my only complaint is that the booklet doesn't state if you can use the needle heads more than once (self use) or dispose of afterwards.

Seeing skin improvement after first use. Well worth the money!

This microneedling pen is wonderful! I have had this done at the spa a few times and it always gave great results, but it's expensive. This is a good alternative. I have owned a cheaper brand pen before, but I never saw results and it was so painful.

This one does not hurt and has several different settings and needles to choose from. This is good because you should not use the same one size fits all for your unique skin types. I have not tried this for hair growth, but I do use it for fine likes and wrinkles. It works well without irritating my skin.

The price is a little high, which normally I would not be okay with... However, I have used cheaper ones with no results so in this case I'd say it's worth the extra money to have a quality product that will actually get you results.
