This unique instrument has a rounded head embedded with teeny, medical-grade needles. When rolled over skin, they create tiny openings on the surface that allow the retinol-and-peptide serum you apply next to absorb more easily.EXPERT OPINION
"The needling tool does help ingredients penetrate the skin's upper layers," says New York dermatologist Jeannette Graf. But if used too vigorously, she warns, it could damage skin.OUR VERDICT
The tool ran over every contour on the face painlessly (granted, we didn't push hard). When we applied the serum from one capsule, it was absorbed in seconds, leaving our skin smooth and not at all sticky.
