I recently purchased the Dr pen M8s and I couldn't be happier with my decision! This product has truly transformed my skincare routine. The 24pin microneedles are perfect for at-home use and have worked wonders on my skin. After just a few uses, I noticed a significant improvement in the texture and appearance of my skin. The roller pen is easy to use and the results are remarkable. My skin looks more youthful, radiant, and smooth. I highly recommend this product to anyone looking to enhance their skincare regimen. It's a game-changer!
