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?

Maybe this is working...
Seems to be working on my menopausal brittle nails. Only used for a week so time will tell. Smells very strong. Nice colour.
