It hardens the nail thanks to the active scientific ingredient that improves the cohesion of the keratin fibers allowing the three main layers of the nail to join together. It also contains crystal resin tears, a gum extracted from the pistachio tree that aids the natural keratinization process of the nails, strengthening them. This penetrating aqueous solution, which is neither base nor polish, hardens soft nails and prevents them from breaking or splitting.
