The hardener from Delia Cosmetics is ideal for strengthening your nails, providing them with the necessary support to prevent easy breakage. It is especially useful for weak and damaged nails, as it helps to prevent their deterioration. For optimal results, it is recommended to apply it on bare nails, as its effectiveness may be reduced if used over nail polish.

This hardener comes in a practical 16ml package, making it convenient and ideal for daily use.
