I've used 4 different foot callous repair products. 2 of them have the same 40% urea and 2% salicylic acid. I'm male, 6', 265 lbs, and I have very rough and calloused feet if I don't regularly maintain them. Maintaining my feet means foot using repair lotions regularly and using one of those hand-held cheese graters for foot calluses. THIS STUFF WORKS! Yes, it's sticky. Yes it has a scent (it's like a tea tree or eucalyptus smell). Yes, it is kind of runny. Yes, you need to spend more time rubbing it in so it fully absorbs. The other product I use (NUVADERMIS Urea Cream) is absorbed quickly and has no smell. But it (and the other foot repair lotions I've used) are not nearly as effective as this AOOHOO Urea Cream. Hands down. When I need serious repair, I used this after showering in the morning and before going to bed. After 1 week my skin is fully moisturized. I then use a callus scraper on my dry feet and the dead skin flakes and scrapes right off with ease, leaving smooth new skin. I love the results! So, despite the stickiness and texture, I'm giving this 5 stars because it works so well.
