Review on Electric Microneedling Pen Professional Kit With 20 Replacement Cartridges And Storage Bag For Face And Body Home Use- Boost Collagen Production And Improve Skin Texture With Derma Pen. by Ryan Huhn

This was exactly what I was looking for. My husband uses it on his scalp for hair loss at 1.5mm and I use it on my face for lines at 0.5mm. It comes with many cartridges and they can usually be sterilized with rubbing alcohol. My husband usually discards after 2 uses. The device charges very quickly and each charge lasts a long time. The case it comes in also appears to be very well made. We really got the bang for the buck when it went on sale and we are very happy with this purchase. No complaints at all.
