UV rays can change the shade of your polish and yellow your natural nails. Protect the integrity of your lacquer's color under a veneer of glossy Verre Naturel UV Top Coat. The specially formulated top coat seals polish and its UV protection keeps color brighter, longer. Used on natural nails, Verre Naturel UV Top Coat prevents nails from yellowing. To protect polish, apply one coat over drying polish; for natural nails apply one coat over clean, dry nails.
