I've just received the Perfect Formula moisturiser from the same range, which I'm using along with the Milagro Nail Care System - the latter is working to a degree, but I still need a little help with hydration as my nails still ping off if I catch one. My nails must be the worst in the world, I have never ever had a decent set of nails, but the Milagro has been about the best thing I've tried (thanks to Clemenzina if you're reading!). I've tried most things, including everything that QVC has to offer..none of it has done much good - things I paint on usually make my nails peel, including Nail Envy, Pro-Strong, Trind, Sally Hansen - of course some things suit and some things don't, we aren't all the same, but I would recommend the Milagro - my nails do now at least have a free edge, and it looks white as opposed to opaque grey, so they are getting stronger I think - I know it takes a long time to grow a whole new nail so am persevering!
Note to Moth's mum - Google Nail Eat & Drink...it's still available, can't remember off the top of my head where I saw it, but it is out there.
