I have been using Super Cop now for a week and once I am done putting it on my face I massage the rest into my hands and nails. Today I filed my nails and normally they file easily but they were so hard it was nearly impossible. I had to cut them instead. I am glad that my nails are hard since they won't break so quickly but is this normal to happen? In just a week?

Dear Sabeine:

Very interesting results - We have known for some time of the effects of SRCPs on nail strength, but that is very interesting that you noticed a difference fairly quickly. And we've seen even better results with the Tin Peptide Nail Renewal

Thanks for posting!
