Despite multiple attempts to perfect process, whilst good for 24hrs, the nail gels do not hold up to every day living for more than 24hrs. Making them expensive gimmick. While 3-5 nails might last up to 3days, heat, water and soap, various activities and products lift or buckle nails makes them lift or fall off completely. Despite instructions saying otherwise, pre-heat does not make them stick better nor allow to stretch to shape (it shrinks back). Finally, cuticles can’t be oiled as also lifts gel so end up looking dry and tatty next to nail. The positive is they do look nice on the nail, and protect nails, just wish they were practical.
