Do you automatically believe everything you read on the internet?
Fura-zone is a very useful product although there are others I like better for most things.
Fura-zone promotes the growth of proud flesh as does any water used after the initial cleaning of a wound. More proud flesh often means more scarring.
On the other hand, you need proud flesh to fill in the gap to close the wound if the skin is completely broken through and the wound was NOT sutured or could not be sutured. Proud flesh is nature's band-aid. It fill in the gap where skin is missing (particularly on the lower leg) and closes the wound to infection. Once the proud flesh has covered in the gap in the skin, then you use something that promotes healing and regrowth of hair. At that time, any water or any product like Fura-zone is inappropriate. You do not want an over-growth of proud flesh.
But, PLEASE do not believe everything you read on the internet. Remember, it is only one person's opinion -- not documented truths.
[ps. Keep your Fura-zone. It is still useful.]
