I have been in search of this product for years— before I knew it existed! This stuff is magical. Let me pause: I use this with Zoya’s entire line, from base coat to nail color to top coat before this stuff goes on top of all that. When used together, the longevity and quality of my home manicures are unmatched. I’ve used OPI. I’ve used Essie. I’ve used Sally Hansen. I have not had the same consistent quality from other brands. The proof is in the mani: so far I’ve had this polish (as described above) since Sunday morning and on Wednesday afternoon I still don’t have a single chip. I’ve been hard on my hands: washing dishes, playing with my dogs, baking. And yet… not a chip. I know the week isn’t over but already this has surpassed anything I’ve ever used and it’s so remarkable I had to post about it!
