Mavala Scientifique K+ Nail Hardner 5ml

Mavala Scientifique K+ 5ml is a nail-hardening serum designed to strengthen soft, weak, and splitting nails by reinforcing the nail's natural keratin structure. Unlike traditional nail hardeners, this formaldehyde-free, vegan formula is made with 90% naturally derived ingredients and targets the most fragile part of the nail—the tip—to help reduce breakage and peeling. Its lightweight, water-based formula penetrates quickly without leaving a surface film, making it easy to incorporate into your manicure routine.
