Hardener

Hardener for more beautiful and resistant nails
The SEPHORA COLLECTION nail hardener takes care of soft and breakable nails. It leaves stronger and more beautiful nails with each application. For a treatment, apply a coat on bare nails on the first day and a second coat the following day. The next day, remove and reapply a coat, etc., for 21 days. Once the treatment is complete, your nails will be 40% harder (1), smoother and have 35% fewer ridges. They will also be less breakable and splitting is reduced by 29% (1).
The hardener can also be used as a manicure base to prolong the nail polish’s hold.
The hardener is available in a transparent or pink version to instantly enhance the nails. The added bonus: its ergonomic brush makes it easy to apply by delivering the perfect amount in one swipe.

A hardener enriched with ingredients from natural origin
This hardener polish is enhanced with pistacia lentiscus resin. It makes the nails more resistant and less breakable. Day after day, they split less and are visibly more attractive.

The added bonus?
