Re: Providone iodine?
My wife and I paint with povidone all the time. And some other family members. We have been using it to dissolve skin blems on our face, and tags elsewhere. Works a peach.
I was at first concerned that it would burn or dry the skin. It has had the opposite effect actually. Like a very gentle exfoliation after a few days. We don't don't it every day. because we forget. So that puts in the on again, off again routine which is probably the best.
A couple of things I added to this: jojoba oil. Paint with povidone first, then put a few drops of jojoba oil on and work it in. Seems to enhance the application and also keeps the skin more supple; and we have also used a handheld ultrasound thingie which was first for joint and muscle issues, but we began to do the povidone/jojoba application on the face and then use the ultrasound device, and it appears to be having the effects work faster. Nice.
So, external use of Povidone has been an A+ around here. Dunno about the age factor tho for your bottle.
