Mavala Switzerland Scientifique K+ penetrating nail hardener strengthens soft, brittle nails that break or peel. Its keratin-based formula improves the cohesion of keratin fibers and helps reconnect the nail’s three main layers. It also contains natural mastic resin, which supports the nails’ natural keratinization process.

The water-based solution penetrates the nail plate without forming a film on the surface. Apply from the middle of the clean nail to the tip, avoiding contact with the skin and cuticles. After application, keep your hand pointing downwards for about 1 minute. Use 2–3 times a week until the desired hardness is achieved, then reduce the frequency of application. Do not use as a base coat.
