For instance...
Yesterday after straightening my hair I put my straightener back in the drawer like I always do. But I was in a hurry and a little bit later was looking for a cotton ball. I stuck my hand in the drawer and the skin on my knuckle instantly blistered up upon touching the 400 degree surface. Without hesitation, I reached in my medicine cabinet and grabbed the toothpaste. I have a tube set aside just specifically for this. :) I put it on the blister, it stung a bit, and put a band-aid on it. I don't recommend a band aid it you can help it because it seems like it feels the best once the toothpaste has dried. By the time we drove into town I had forgotten about it and bent my knuckle which made it hurt again. So I took the band aid off to let it dry. And by last night I could bend my finger... until I ripped open the blister changing Addison's sheets. :(
Being very pale skinned, I used to get burned really bad in the summer. Once I fell asleep on a black inner-tube and what the most burnt I had ever been. My mom mixed the toothpaste with water and put it all over my body with a toothpick. I couldn't stand for her to dab it or smear it with her finger so this way worked great. I just laid there on trash bags watching tv as it dried but I was just fine the next day. I've done this later and life and you could smack my burn the next day and I was just fine.
My sister worked at KFC in high school and got a grease burn on her arm... toothpaste applied.... later it still had a blister but wasn't sore!
I'm telling you this is amazing stuff!
