Mavala Scientifique Applicateur is a specialized nail hardening treatment designed to strengthen weak, soft, and splitting nails. This penetrating solution works by improving the cohesion of keratin fibers in the nail plate, helping to bond the nail layers together for enhanced durability. The product should be applied only to the tip/free edge of clean, polish-free nails, avoiding contact with cuticles and surrounding skin. For best results, apply 2-3 times per week until desired nail hardness is achieved, then reduce frequency for maintenance. The formula is neither a base coat nor nail polish, but rather a treatment that can be used under regular nail polish. The applicator format allows for precise application to the target area.
