We have all been there: a corner of your gel manicure begins to lift while you are watching TV or sitting in traffic. The temptation to slide your fingernail under the edge and peel the entire sheet off in one satisfying flick is almost irresistible. Stop right there!
Peeling off a gel manicure is the single most destructive action you can inflict on your hands. Here is the microscopic science of what happens when you peel:
During photopolymerization, the gel base coat forms thousands of microscopic chemical anchors that weave into the porous, fibrous surface of your dorsal nail plate. When you forcibly rip the hardened gel off, the polymer bond does not break—the natural keratin fibers tear instead. Peeling rips away 30 to 50 layers of dorsal keratin cells in a single second, leaving white chalky patches (known as keratin granulations), thinning the plate by up to 30%, and exposing raw, hypersensitive bed tissue.
