Coconut oil work wonders for impetigo. My daughter had impetigo. her doctor prescribed iodine and Bactroban cream which worked well. But recently she has break out on the lips inside the mouth. I tried the cream for a few days, but it does not help much because of the saliva. So I tried coconut oil. Wow, it works so fast! I appllied VCO on her lips just like applying lotion before sleep and the next morning the lesion became black and dried up.
