Whether or not you can apply frostbite cream after frostbite also depends on the condition of the frostbite. If the frostbite formed is relatively mild, frostbite cream can be considered. If a blister forms after frostbite, the first step in this case is to disinfect the blister, extract the blister fluid, and preserve the blister skin. If there is a combination of infection, treatment with sensitive antibacterial medications can also be used, and local dressing changes can be reinforced. For patients with frostbite, frostbite cream is a compound preparation containing camphor 30mg, boric acid 50mg and glycerin 50mg, of which camphor has the effect of promoting local skin circulation to relieve pain and itching, while boric acid has mild antibacterial and anti-inflammatory effects. Its usage is topical, after washing the wound with warm water and gently drying it, take the frostbite cream and apply it to the affected area and rub it gently. However, if a burning sensation, redness or swelling occurs at the site of application, the drug should be stopped promptly and the area should be cleaned, avoiding contact with eyes and other mucous membranes and not used for skin destruction. In case of side effects, it is also necessary to receive formal treatment at the hospital to avoid aggravation of local trauma symptoms.
