CND Shellac results in a durable, high-shine finish which is completely dry once cured in the lamp , therefore smudge-free too. Once applied to natural nails, it provides an extra layer of protection and strength. When applied over nail enhancements, it provides long-lasting colour until the next service. There are a number of different finishes including, gloss, glitter, opaque, sheer and metallic which can be applied over the huge range of shades.
