The PH of your urine can vary. Urine is also not sterile, so you are introducing waste products, bacteria, and salts directly into your skin holes. The urea concentration isn't especially high at 2%, compared with topical solutions that start at 5%. CeraVe and Eucarin both have a product with urea in them.

You are right, in that urea does break down into ammonia. So aged urine was used to tan hides, since the ammonia would break down the leftover fatty tissue/grease, and loosen all the hair and fibers.

    Thanks for a bit more background on the facility on the island. With such a rich history, including being Charles Manson's home for a couple years, I'm surprised I don't have that fact locked away for trivia nights.

    Also, thanks for setting a good example for citing your source. I'll follow your lead the next time the source of my info isn't made up or pulled from my ass.
