Review (1/5): Not all natural!
I'm giving this one star for false advertising! When I ordered this, I thought it was an all-natural. However, not all ingredients are listed. It's primarily a high dose of Urea 40% and includes salicylic acid (2%) and other chemicals. See the ingredients on the packaging. For this reason, I have downgraded my rating. Nor are there any warnings in the description or on the packaging to keep away from eyes, mouth, and lips and wash your hands thoroughly after applying. As effective as urea is and it's generally recognized as safe, there are some warnings about breast feeding as well.
I know that urea and salicylic acid are excellent compounds for skin softening and can be used for things as serious as psoriasis, especially at that amount. I haven't used this for two weeks as I felt my warning was important, but I know it will be effective, having used urea/salicylic acid compounds in the past with great results of softening calluses and dry heels.
If the correct ingredients were listed, I would give this a higher rating. I just don't like the deception!
