I have been using UT for over a year now, both internally and externally and I have been experimenting with using a higly reduced concentration of urine as skin treatment. I wonder if anyone has any feedback?

To do this, I cook urine in a pan very slowly, just below the boiling point, for 3 or 4 hours until it has reduced to about 1/20 of the original volume. By the end it has gotten dark and syrupy. I stop when the vapor rising has almost no smell at all.

What I end up with is somewhat oily with lighter colored tiny semi-solid grains in it, though the grains will gradually mix back with the rest of the liquid as I use it over a couple of weeks. It seems to be a good skin conditioner and the smell is somewhat smokey but less noticeable than aged urine. Only a couple of drops are plenty to cover my face since more that that leaves the skin very sticky. It seems to keep for several weeks with no noticable change.

Does anyone else out there have experience with this or do you know what the lighter colored grains are?
