Mavala Nail Care Scientifique K+ Nail Hardener

• The tip of the nail is the most fragile, most unprotected part and breaks easily. This is therefore the part of the nail to be strengthened. • Mavala Scientifique K+ hardens the nail plate thanks to a scientific active ingredient that improves the cohesion of keratin fibres thus allowing the three principal nail layers to bond together. • It also contains crystal resin tears, a gum extracted from the pistachio mastic tree that helps the natural keratinization process of nails, reinforcing them. • This penetrating aqueous solution, that is neither a base nor a nail polish, hardens soft nails and avoids them breaking or splitting.
