Who hasn't tiptoed around in a fresh paint job and accidentally smudged it? If the polish is still wet, just apply another layer of color onto the entire surface, followed by your topcoat. If you spot dents once nails are dry, stroke a sheer, sparkling shade over all 10 of them. Shimmer reflects light and distracts from imperfections, says Hipp. "It'll give the illusion of a brand-new pedi."
