I am Faye and this is the derma roller from QMD. This derma roller is great it is made of Stainless-Steel needles which is actually better than the Titanium needles.
This is the .25mm and this is perfect for helping your serums penetrate even more deeply and they’ll be that much more effective for you.
So definitely check this out if you are looking for a derma roller. Thanks.
