Mavala Scientifique Applicator is a professional nail hardening treatment designed to strengthen weak, brittle, and splitting nails. This innovative formula comes in an easy-to-use applicator pen that helps improve nail durability and prevent breakage by reinforcing the nail's natural structure. The product features a precision applicator tip for targeted application to the nail tips where strengthening is most needed. For best results, apply to clean, dry nails before using other nail products. The formula works by penetrating the nail plate to bond the keratin fibers together, creating stronger, more resilient nails. Regular use is recommended until desired nail hardness is achieved.
