This unique, 5 in one treatment contains Micro Cell's special 2000 formula to protect and nourish nails. With silicone-like properties, it can be used as a varnish to seal and penetrate the nail, protecting it against drying and flaking. It can also be used as an instant drying top coat to prolong colour and shine, as a sealer to prevent peeling, as a colour refresher, and finally as a ridge filler to smooth the surface of the nails.
