Mavala Scientifique K+ strengthens the nail plate by using a scientifically developed active ingredient that enhances the cohesion of keratin fibers, allowing the three layers of the nail to bond more effectively. It also contains crystal resin tears, a gum derived from the pistachio mastic tree, which aids the natural keratinization process and reinforces the nails. The tips of the nails are the most delicate and prone to breakage, so it's crucial to fortify this area for healthy, strong, and evenly shaped nails. This penetrating aqueous solution is not a base coat or nail polish. Mavala Nail Hardener helps to strengthen soft, brittle nails, preventing them from breaking or splitting. If your nails are extremely thin and frequently break, try using Mavala Nail Hardener for a few weeks to see noticeable improvements!
