A friction burn is a form of abrasion caused by the friction of skin rubbing against a surface. A friction burn may also be referred to as skinning, chafing, or a term named for the surface causing the burn such as rope burn, carpet burn or rug burn. Because friction generates heat, extreme cases of chafing may result in genuine burning of the outer layers of skin.
|Other names||Carpet burn, rope burn, rug burn, sand burn|
|Friction burn caused by a rope|

The dermal papillae may be exposed after top layers of the dermis (stratum corneum, stratum granulosum, stratum spinosum and stratum basale) have been removed. This is often uncomfortable and even painful, but rarely results in bleeding.
A person's own skin (or the skin of another person) may be sufficient to act as an abrasive surface to cause friction burn. More commonly, friction with abrasive surfaces, including clothing, carpet, or rope, can lead to a friction burn. Common places at which skin-to-skin chafing can occur are between the thighs and under the armpits. Friction burns are very common with clothing such as trousers on the knees caused by playing sport or sliding on wooden surfaces.
Most minor cases of a friction burn require little to no treatment, as a specific case of allergy might aggravate the burn.
