CND Vinylux™ is a breakthrough polish that endures a week of fashion perfection, without a base coat. Week-long wear, time-released durability and self-adhering colour coat. CND Vinylux™ Weekly Polish and Top Coat: a system uniquely designed to work together. Patent-pending Pro-light technology creates a powerful network of cross-linked polymer bonds that builds resistance to chips and enhance durability with exposure to natural light over time. While ordinary polishes become brittle and deteriorate over time, CND Vinylux™ dries to a flawless finish and strengthens its resistance to chips over time to deliver a truly long-lasting polish.
