Innovative, matt-finish treatment base coat that grips colour to help maximise wear and reduce chipping.
UNDERCOVER is shiny when applied it turns matt when dry to highlight it’s time to apply the next coat. It also has colour diffusers to mask nail discolouration and even tone, and special ingredients famed in the nail industry as having strengthening qualities.
Apply a thin coat of UNDERCOVER over a clean dry nail. Apply the colour coat when UNDERCOVER changes from shiny to matt.
