Hi, I am using fresh and 3day old urine to clear up styes and a cyst on the eyelid. The old urine seems to have the greatest effect on reducing the condition. New urine is the most soothing. I would say every time you have a pee, put some on your eye with your finger, assuming you are a bloke. If you'r a woman, it's quite good for taking off eye makeup so don't spoil your face! Good Luck, Love and Light , Deotima.
