Protect your polish with the Top Coat Nail Varnish from the industry’s most innovative brand, CND. Inventors of the original SHELLAC, CND have used the power of science to revolutionise the nail industry for over 40 years. This topcoat uses ProLight Technology™ to shield polish from scratching, chipping, dulling or denting for up to a week. This advanced technology even harnesses the power of the sun; cross-linking polymerisation is activated when nails are exposed to natural light, increasing durability. For long-lasting, professional-looking nails – look no further. Shake to blend. After painting nails with colour, finish with one layer of CND VINYLUX Top Coat.
