Blown away

I am very unexpectedly pleased with this base coat. One application is enough to keep your polish on your fingers for good. It's definitely worth the price! I will be coming back for more.

Very impressed

The base coat is great. Really adheres to the mail and help keep the polish on. I was able to keep my manicure mostly intact for 7 days—which I consider a big win!

Definitely a new favorite

Honestly , I love this! Love the repackaging and for the price , it definitely feels and behaves like a luxury brand of nail polish base! I wish the brush was more flat and rounded like a few companies are changing their brushes to. But other than that, It’s perfection!

Works great in preventing cracks

I was gifted by The Foundation their Ten over Ten strengthening base coat, my nails have been so brittle lately and chip so easily. I been applying this base coat to my nails and I have seen noticeable results of my nails be a lot more healthier and stronger and finally starting to grow long again. I also like to apply this under my nail polish which works just as good!

Just what I needed!

I love this product! My nails started peeling in the last two years. I found a great product to treat them, but I wanted a product that acted as both a treatment AND as a base coat so I could still wear nail polish. This product is exactly what I needed. Works well and lasts!
