Whether you suffer from thin, weak nails or just like the finish of a thick, glossy manicure, Rimmel's 3D Plumping Topcoat (£4) is the product for you. It's the latest in a long line of special-effect topcoats, but unlike crackle and matte, it's one that we think we'll still love a few months down the line.
The aim of this topcoat is to add volume, which might not sound like something you want on your nails, but it can help to hide small ridges and dents,and keep your manicure looking neater for longer. A plumping effect will battle the shrinkage you often get with some brands of nail polish, so you'll need to touch up or repaint less often. Use it to keep glitter polish in check, or add over a bold colour for a bright, glossy finish. It even works on bare nails — great for those who are trying to stop biting.
