Dr. Pen A9 Professional Microneedling Pen - Wireless Derma Roller with Adjustable 0.25mm Needle Depth - Electric Skin Care Device for Face & Body (Includes 6 Cartridges) - Reduce Wrinkles, Acne Scars & Boost Collagen at Home

Easy to use, lots of options, paid for itself in one treatment!Starting out home micro-needling and I started on my breast to see if I could get rid of some stretch marks. With plenty of hyaluronic acid the needle works great up to 2mm. I did test a patch on my thigh, where I also have some stretch marks, and I can't get the needle to work well at any depth greater than 2mm. Perhaps it is my technique, but I changed nothing and as soon as I go above 2mm the needles begin to catch and stop gliding. Either way it's a fair product for the purchase price, just be aware that you may have issues going to greater depths with this needle.Great product!This is awesome. This is just like the skin pen you would get from an estiticiAn. But you can do a ton of treatment for less that one if you went somewhere. There are tons of good reviews of micro needling and this product makes it much easier to go deeper than with the rolling devices thus getting more results. Make sure you NEVER drag the skin pen. Pick up each time to go to a different spot. Use really good products after too.This is the first time I tried micro needling. It was easy to use. A little scary the first time since I did not know what to expect. It helped with the overall redness of my face and pores. I only used 2 times and see a little difference in the texture of the skin.I saw some YouTube videos of people microneedling at home and this was a top recommendation. SO glad I took the plunge and got this pen because it has changed my skin substantially in just the two months I've been using it. Replacement cartridges for this unit are affordable and easy to find.Fácil de usar, funciona muy bien es muy bueno para la piel lo utilizo con algunos productos de ácido hyaluronicI loved it
