Springtime means a bevy of bright lacquer hues to adorn our fingernails with, but changing your polish so often can leave you with brittle, ridged nails. Londontown has your answer, though, with its Kur: Restorative Nail Cream ($35). Just a drop of this silky, vitamin-laden cream massaged into your nails renders them good as new. It's like a night cream for your nails. Regular use restores your nails to their full glory. They're shinier, well hydrated, and look so great, you may want to forgo the polish altogether.
