This is the best product for lip exfoliation I have ever used. My lips are always dry and flaky. I have tried scrubs, lip masks, lip oil and this plastic tool. Some of them worked for awhile but ultimately, the flakes returned. I tried this as soon as it arrived, and I was amazed. My lips have been smoother than ever. The real genius part is that it is in pencil form. No messy cleanup, no little containers that always get lost and I can throw it in my purse so I can have smooth lips.
