I use this as a base Coat on my nails as it keeps them nice and strong. Great for when your spend a lot of time with your hands in water

Revitanail Kerartin nail strengthening serum is a product that delivers results to fix poor nails.It is easy to use and it is one of the better products to buy.

I tried this awhile ago as my nails were splitting all the time so I gave it ago. Goes on well but doesn’t really stay on the nail for very long found it peeled off after a few days. But it did help stop the splitting after persevering . But rather dear.
