Why on earth do you want to put
Lugols on your face?
It can work as a facial if done daily for a few days, it will burn and you will look pretty bad for a couple of weeks. But if you are persistant, new skin will arise. No damage done to the new skin.
Lugols may be used as removing moles and pigment spots, also on the face, it takes up to a month of daily painting, sometimes two.
A better option for the face, is mixing
Iodine with a tiny amount of vit C (just enough to clear the iodine)
-this will tighten and rejuvenate the skin, but not burn it.
Painting the skin / spots just now and again, will cause no damage, so the question is what is your aim?
