I have been wanting to try one to see if it will help my almost 40 yo skin. I’m so happy I did. It doesn’t hurt AT ALL but you know it’s working. I use the metal roller in the morning to reduce puffiness and the microneedler 2-3x a week before applying my serums. It’s very well made and I can’t wait to see results after 4-6 weeks. #rankboosterreview #sponsored #dermarollericerollerkit
