I just got a burn from a straightener that I thought was off, on my index finger, about an inch long with blistering, and am online researching. According to what I read under 'first aid for burns", medical professionals treat any burn with blisters as serious because it's difficult to tell the difference from 2nd and 3rd degree burns since both have blistering of the outer layer of skin. 2nd degree means destruction of the outer layer (epidermis) and there is blistering and possibly redness. 3rd degree goes deeper with destruction of the dermis and possibly nerves (patient wouldn't necessarily feel anything) and there can be blackening, though not necessarily.
I think it would be determined by how long your skin was in contact with the heat and how big a surface area was in contact.
If you think it might be third degree, get medical help IMMEDIATELY. (Larger areas or burns like whole fingers, hands or feet or around arms or legs or neck (obviously not straightener burns) can swell and cause constriction that dangerously cuts off blood flow to the limb, or prevents breathing. Obviously large burns of any type require emergency medical treatment by a professional!)
Recommended treatment I found online: (a) immediately running cold water over the burned area to remove the heat; do NOT use oil or butter! the old wives remedy; (b) I iced it for more cooling and pain relief though I didn't see this advised; (c) bandage it and (d) when the blister pops and skin separates, use antibiotic ointment and keep clean and loosely covered to keep it from getting infected til it heals. (e) After it heals for the next month, use sunscreen on the new skin, plus Mederma to help minimize scarring.
First degree is a a thin burn like when you barely touch your finger on a straightener or curling iron. Second degree is a little more serious and you get that when you burn your hand or something on a flame. And third degree are bad burns that you can get all over and you bleed and you have burns all over... my uncle lost his arm in a third degree burn when he was around my age (13) by accidentally touching a low power line that was by the pool.
Third degree is the most severe.
Charring IS a third degree burn. Third degree burns cause blistered and charred skin. It can also cause your skin to melt.
Yes, a 3rd degree burn is a full thickness burn.
Third degree / full thickness burn
A full-thickness burn is a third degree burn.
A third degree burn is a burn that extends completely through the dermis. The degree of burns measures the severity (or depth) of the burn. Third degree burn does not mean it covers more than 1/3 of the body. In that case you would be informed that 3rd degree burns covered over 1/3 of the body.
The burn needs to be deep enough to damage the hypo dermis and cutaneous layer.
The amount of damage. A first degree is usually redness and pain, a second degree burn blisters and a third degree burn destroys tissue.
Depending on the severity of this third degree burn you will either feel it just as much - if not more so - as with a second degree burn, although in third degree burns you risk nerve-damage, which will make you partially numb to the pain in some areas of the skin.Either way you will feel the pain of the burn, as the bordering skin will not be as affected by the burn and hence feel the pain of first and second degree burns.
A third-degree burn extends below the dermis.
Probably a second. It's marked by blisters.
