3 In 1 Hardener


A multifunctional preparation with an active hardener. A preparation to be used as: nail plate hardener, primer protecting against coloured enamel, surface polish protected against matting and providing longer-lasting effects. Its formula, which reduces nail softening, prevents splitting nails. It contains methionine which hardens the nail plate and prevents the nails from breaking and discolouring. How to use: apply one/two layers of the preparation directly on the nail plate on its own or under nail polish or as a top coat.
