Nail Repair Extra Strength Strengthening Varnish
Its exceptional formula binds the nail's Keratin proteins in a process called "cross-linking", ensuring the cohesion of the nail's three layers, making it strong, while retaining sufficient moisture to keep it supple and from becoming brittle.
Directions for use:
As a treatment: Apply once a day for 15 days, after Nail Balsam Moisturizing Serum
Remove every evening with extra-gentle, acetone-free nail polish remover.
For maintenance: Apply once a week, after Nail Balsam Moisturizing Serum. The serum can be used daily for maintenance.
