Old vs New urine on face ?

Hello everyone and thank you in advance for your time.

I tried using old like, 20 day old urine, on my face, but the smell and aroma is absolutely SHOCKING, there is NO WAY to hide this from your family. And it stays for hours, I tried mixing half a bottle of eucalyptus oil and still no use.

But fresh urine on the face, I find very refreshing and I even feel my skin tightening (not so with old urine)and not much smell remains after 5 minutes or so.

My question is: is there proof that old urine is far superior for the face? I mean I tried it for about a week and saw no major difference then the fresh urine. If so, then what do you people do to hide the smell of old urine? I mean if you just walk in to a room and leave, the ammonia and horrible smell stays there for half an hour.

I thank you all in advance.

Fatboy.
