Superficial burns
Superficial burns only affect the surface of the skin (epidermis). Your
skin will be red and painful, but not blistered. Mild sunburn is an example of a
superficial burn.
Partial-thickness burns
Partial-thickness burns are deeper burns that damage your epidermis
and dermis to varying degrees. If the damage to your dermis is shallow, your
skin may be pale pink and painful, with blisters. Deeper burns to your dermis
will cause your skin to become dry or moist, blotchy and red. Deep partial-
thickness burns can be painful or painless and may blister.
Full-thickness burns
All layers of your skin are damaged by full-thickness burns. Your skin will
be white, brown or black and dry, leathery or waxy. Because the nerves in
your skin are destroyed with full-thickness burns, you won't feel any pain or
have blisters.
Symptoms of burns
If you're burned, you may have symptoms such as:
• changes in skin colour - burns can cause pink, red, white, brown and
black skin
• blisters
• pain in the burned area - but pain from burns isn't related to severity
Symptoms of an airway burn include:
• burned nose hairs
• soot in your mouth or nose
• change in your voice
• sore throat
• wheezing
