The Dr. Pen Ultima N2 Microneedling Pen is the same one used by most professional beauty spas, and you can use this at home to achieve the same results. I have used Microneedling equipment from a couple of different makers, and I find the Dr. Pen to be a solid and reliable pen that I favor over the others. Do yourself a favor and look at several Microneedling tutorial videos here on the Dr. Pen Amazon product page or elsewhere before you do this at home. Microneedling literally pricks micro-sized holes in your skin to encourage collagen production and to directly insert beauty serums under the skin to make them more effective. The bad news is that with speeds ranging from 8000-16,000 pokes per minute with the included 12-point needle tip bayonet cartridges, you can hurt your skin, so exercise caution. The good news is that when done right, most dermatologists and cosmetic surgeons agree that you can get professional results at home with this procedure when used properly. Use on any body part including lips and under the eyes. The process does hurt, so you may want to invest in a skin numbing cream as well. Follow the highest sanitary and safety procedures for best results. Don’t push the pen too hard, and practice at settings below .50 to start. When you can handle the pain, go to deeper levels with the tip adjusting collar. This works great getting rid of acne scars and redness and large pores, and can also refresh lips. The Dr. Pen Ultima N2 comes with a set of 5 disposable bayonet cartridges and a USB charging cord and manual. Be sure to read the manual. It helps and watch the videos. For the cost of less than one professional treatment, this dandy little pen may become the one item in your beauty arsenal you cannot live without.
