Foundation Xtra 4, Ridge Filling Strengthening Base Coat for Weak and Damaged Nails, 0.5 oz, 2-Pack

I really like this stuff. It is matte and clear as if you did not even have on any polish. It will stay on by itself for two or three days. It will stay on longer than that if you continue to add coats of polish to the top.

Just okay

I have been using this for 6 months and my nails are much improved and i am very happy with the results. My issue is that the bottles i had before (used as base coat and top coat) leeft a clear shiny finish. The bottle i just got is a satin finish and not quite clear. I didn’t see where there was a note that they were changing the finish!I want the clear shiny finish!! How do I get that again??

I like this product and have used in the past. I need to stay with it. Tried, true and tested!

This product will improve your nails.

This product filled in the ridges on my nails & made them smooth so I got smoother coverage from my nail polish.

For the last 20 years I've been using acrylic, gel or dip on my nails...and they are totally hacked by now!! I decided to bite the bullet, and stop going to the salon. I got one last dip (french) and have let them grow out. The dip has kept the ends of my nails strong during the tedious process, and I just keep filing them very, very short. No, they don't look great, but after months they are nearly all grown out.However, after growing out, a few of the nails have ridges, so I wanted to find a product that would smooth out the ridges. This isn't it. In fact, I tried putting 3 and 4 coats of this product on each nail but they still aren't smooth. I like the polish and will keep using it, it just doesn't fill the ridges.

I use this as a base coat before putting on polish. Not sure it really works.

Great and it keeps my nails strong

I would not buy this or advise anyone to buy, because it has formaldehyde in it. The bottle says, don’t let touch skin, causes cancer. So if you buy anyway, it’s non-refundable , so you are throwing your money away .

Poulur les ongles c'est bien mais il n'y a pas d'instruction d'utilisation. On doit mettre 3 ou 4 couches.Le produit ne résiste pas à l'eau que ce soit le bain ou la douche ou la vaisselle et un produit de finition aide un peu.Au bout de 3 jours c'est écaillé et à recommencer. Les ongles ne brillent pas avec ce produit ci et sont cassants.

Used to improve mail health.. When used and hands used soap detergent, my nails went blue.Not impressed. If I was not out of the country after receiving I would return it for a full refund.Unfortunately When it arrived I used it once in prep of my trip. Very disappointing.
