Overview
Painting this MAVALA hardener from the center of the nail to the tip targets the most fragile edge. Its active ingredient improves keratin fiber cohesion so the nail layers bond, and pistachio mastic resin supports keratinization.
Hardening only the tip strengthens the part that breaks while leaving the rest of the nail flexible. It needs careful application away from cuticles and skin.
Who it's for
Soft nails that peel at the tips suit a targeted hardener under polish. Those whose nails snap from dryness should look for a hydrating treatment.
Pros and cons
- Targets fragile nail tips
- Pistachio mastic resin
- Works under base coat and polish
- Small bottle lasts
- Must avoid cuticles and skin
- Application is fiddly
- Not for brittle, hard nails
Performance notes
The active ingredient helps the three nail layers stick together, which reduces splitting at the free edge. Applying only from center to tip concentrates hardening where breaks start. Regular use a few times a week maintains the effect.
