This is a Derma Roller.
Yes. It has needles.
Yes. I can cause microscopic bleeds in the tissue
Yes. It pokes holes in your skin. As those needles roll across your skin, they create small triangular tears in your skin.
Would I use it on my face? NEVER!
I WOULD BE VERY WORRIED ABOUT WHOSE SKIN IT WAS USED ON BEFORE ME, AND WONDER HOW IT WAS STERILIZED.
Instead of causing direct injury and inflammation to your skin, learn how to build it up & strengthen it. Your esthetician can help.
