This is going to be a very quick and matter-of-fact review.
I have nice, long nails but their surface is very uneven. I used to file and buff my nail plate or didn't bother at all until I discovered Essie Ridge Filling Base Coat.
This is a pastel peachy coat that evens out the surface perfectly in one coat. It dries almost instantly and acts as a perfect base for nail polish, providing the kind of grip I like.
When topped with nail polish my ridges become invisible and my nails look so smooth and polished. I feel I've found my perfect base coat which I'm going to repurchase until it's discontinued.
The only thing I don't understand is the anti-age claim. I have no idea what this means, so I won't comment upon this as the primer is just perfect whether it does have any anti-ageing quality or not.
