Mavala Scientifique K+ Nail Hardener 5ml

Mavala Scientifique K+ Nail Hardener 5ml hardens the nail plate thanks to a scientific active ingredient that improves the cohesion of keratin fibers thus allowing the three principal nail layers to bond together. It also contains crystal resin tears, a gum extracted from the pistachio mastic tree that helps the natural keratinization process of nails, reinforcing them. This penetrating aqueous solution, which is neither a base nor a nail polish, hardens soft nails and avoids them from breaking or splitting.
