Early morning pee urine. Use a cotton swab to add it to the infected area. It is how I treated my acne as a teen. Does it work? Well after you apply to your face, you should feel a cool sensation to your face. To me, it is the active ingredient working.
Pee has a ton of nutrients and early morning urine is 8 hours worth of fermented urine stored in your body. It gets toxic if kept in your bladder so use toxic stuff to kill bacteria.
Logic makes sense but I don't know the science behind it.
