Scientifique K+ Nail Hardener with Applicator from Living Proof is a pen-shaped penetrating aqueous solution that hardens the nail plate thanks to a scientific active ingredient that improves the cohesion of the keratin fibers, thus allowing the three main layers of the nail to unite. This penetrating aqueous solution, which is neither a base nor a varnish, hardens soft nails and prevents them from breaking or chipping.
