A burn that only affects the first layer of skin is called a first degree burn.
A 1st degree burn affects the outer layer of the skin. The 2nd degree burn affects the outer layer of the skin and the layer just beneath it. A 3rd degree burn involves all the layers of the skin tissue's beneath them.
The burn needs to be deep enough to damage the hypo dermis and cutaneous layer.
The epidermis
* A partial thickness burn (second degree) affects both the outer layer of skin and the layer that lies underneath it (the dermis). The skin may have large blisters and the tissue is deep red, wet, and shiny. These burns are very painful.
A first degree burn will have redness. It will also feel hot to the victim. But it only involves the outer layer of the skin.

This is a second degree burn, as it has blistered. This means more of the skin was affected than the epidermis, or upper most layer of skin.
It is the least serious of burns. Only the outer layer of skin is burned.

4th degree burn
This kind of burn is called an Alkaline burn. Salt is an Alkali, and when put on the skin and covered with ice the combination removes moisture from the top layer of skin. The Alkaline nature of the salt then burns the skin more readily since it's now been dehydrated from both the ice and salt combination.
