VINYLUX is a breakthrough polish that lasts for 7 days! There is no need for a base coat as it will negate the performance since the adhesives are already in the color coat. The patent pending technology works with natural light to create an enduring, long-lasting polish. While ordinary polishes deteriorate over time, VINYLUX dries naturally to a flawless finish and strengthens its resistance to chip over time.DirectionsFor best results, prep nails first with ScrubFresh. Shake Vinylux Weekly Polish. Apply two thin coats, and finish with one coat of Vinylux Weekly Top Coat. No base coat required!
