No Lift Nails Liquid features a sun block that filters out harmful U.V. rays which can cause yellowing. Our unique liquid is designed with a "cross-link" effect which activates when mixed with No Lift Nails Powder. Our lab-grade liquid contains no methyl methacrylate. It has the added benefit of allowing "Wet-Brush" �Fast Setting� application for a better finish, with less buffing and less finishing work.
