However, if contact with the aerosol is prolonged the skin will freeze further and deeper layers of tissue will be affected, causing a more serious burn that reaches the dermis, destroys nerves, and increases the risk of infection and scarring. [6] When the skin thaws, pain and severe discomfort can occur in the affected area. [7]

[1] The episodes classically result in the affected part turning white and then blue. [2] Often, numbness or pain occurs. [2] As blood flow returns, the area turns red and burns. [2]

[2] Healing can require up to eight weeks and scarring may occur. [2] In a full-thickness or third-degree burn, the injury extends to all layers of the ...
