Hardener
A nail hardener enriched with pistacia lentiscus resin for stronger, more beautiful nails in only 21 days.
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?
- Vegan hardening polish (free from animal-derived ingredients).
- 81% of ingredients from natural origin.
(1) Measured scientifically on 22 volunteers after 21 days’ use.

Looking good……
I’m only 12 days into my 21 day treatment plan, and already my nails are looking great! They had become so weak, split, chipping and generally a real mess! They are now neat and looking well kept. Although quite short at the moment, the new growth is clearly much more healthy, stronger and very attractive. I’ve ordered a second bottle as I’m going to try it on my toe nails now!
