Skin contact with dry ice can be treated by applying heat to the surrounding skin and by using frostbite cream. Dry ice is solid carbon dioxide with a temperature of -78.5 degrees C. Direct contact with the skin will result in local frostbite at the contact site. The external application of frostbite cream on the damaged skin can activate blood circulation and remove blood stasis, and produce muscle and astringent sores. It is recommended that patients should avoid direct contact with dry ice, and if frostbite is serious, they should go to a regular hospital and ask a professional doctor to treat it in a timely manner to avoid skin necrosis.
