I had this from a while now, enough to test it and be sure it actually works. This is basically a very hydrating oil for your nails cuticles. It's enriched with vitamin-e and sweet almond. 

It protect my nails and polish, leaving them shiny, soft and without trace of cuticles or dry skin. 

And for a lot of time! I can wash my hands at least 3 times and the nails still feel nourished and healthy. You can see the difference on the pic below 

The smell it's ...OK, pleasant enough (smells a lot like olive oil ) however it goes away as soon as it dries.

So it works very well for me and I can use it after or without my usual polish.
