Eh [SEP] I watched multiple videos of how to use tools like this before I bought any, and I've followed the instructions, but I find these don't do much except leave my skin red and puffy. The loops do work okay on my nose, but that's about it. I find that the amount of pressure needed to make anything come out is much too close to the amount needed to break the skin, and sometimes it leaves marks. Maybe I have bizarrely thin skin, but that's my experience. I also only use the thickest tool, so I hate that I spent extra money for a set.
