Uncertain
No change in appearance of nails, the ridged areas are still splitting. Maybe not the right product for this issue. Maybe the maps are strengthening from within.

Is a clear strengthener - no colour
Nail Envy Pink to Envy - the OPI website is entirely misleading in the colour of this strengthener. I purchased as looking for a natural pale pink easy to wear all week. Pictures show this on nails where the nail tips are barely showing through, so the colour should be a little sheer but definite colour, however this is simply clear even after 7 days of building up coats. Not what I wanted at all. Is just a clear strengthener so I wasted my money.

Disappointing
I've applied the serum as directed, but amdisappointed to see no real improvement. I might as well use the whole bottle and hope it will eventually improve my nails. Maybe they're beyond salvation?
