Its promise (as stated on package):
- stronger looking and feeling nails
- smoother nails instantly
- shiny glossy top coat that lasts for days
As I said before, my nails generally have no problem with breakage, as they're pretty strong, so I cannot comment on the first promise. Having nail varnish on for the most part makes the nails feel stronger, anyway. Yes, my nails instantly felt smoother after putting it on, however, it feels that way with any nail varnish I put on, so nothing special there. The third point is probably the one of interest. On the third day, I noticed the varnish starting to lift at the tips of my fingers. I think one of them even lifted during my shower. That creates this bulge at the tip, where the varnish seems to have lifted and bunched up together. Also, the bottom part of the nails are starting to show due to varnish shrinkage. Not a pretty look. I tolerated that, since my nail beds weren't significantly showing. On the fourth day, bits of the varnish chipped off during shower time.
