Uncontrolled cooling, however, can result in freeze burns to the skin. According to controlled laboratory experiments, the gas from a typical deodorant spray can reduce skin temperature by up to sixty degrees Celsius. [2] The form of injury is freezing of the skin, a type of frostbite.
Frostbite is a skin injury that occurs when someone is exposed to extremely low temperatures, causing the freezing of the skin or other tissues, [1] commonly affecting the fingers, toes, nose, ears, cheeks and chin areas. [6]
Diagnosis is based on symptoms, but imaging can help assess viable tissue and risk of amputation. [6] Pre-hospital treatment involves transfer to a warm environment, changing wet clothing, and rapid rewarming with warm water if refreezing is not expected. [11]

Freezer burn is a common problem, but what causes freezer burn and how can it be prevented?
Treatment depends on the severity of the burn. [2] Superficial burns may be managed with little more than simple pain medication, while major burns may require prolonged treatment in specialized burn centers. [2] Cooling with tap water may help pain and decrease damage; however, prolonged cooling may result in low body temperature.
"Freezer burn increases oxygen contact with the food surface area and raises oxidative reactions, which irreversibly alter color, texture, and flavor," writes Evans.
A thermal burn is a type of burn resulting from making contact with heated objects, such as boiling water, steam, hot cooking oil, fire, and hot objects. Scalds are the most common type of thermal burn suffered by children, but for adults thermal burns are most commonly caused by fire. [ 2 ]
