When your baby has frostbite on the face, apply topical frostbite cream twice a day depending on the rash, if there is no breakout. If there is breakout, apply topical application together with Bactrim ointment. Pay attention to the care to prevent cold and frostbite. There are two reasons for frostbite: 1. poor local blood circulation and insufficient blood supply; 2. cold surroundings, especially when there are drastic changes in heat and cold. For small babies, the first thing you should do is to keep warm, put on a scarf and hat when you go out to avoid direct contact of cold air with your face. When you come back indoors, it is not recommended that the temperature difference be too great, and it is recommended that you turn on the heating or air conditioning when you return to your room, especially not to wash your face with overly hot water when it is cold. If there is only erythema and itching and the skin surface is still intact, topical vitamin E ointment, mucopolysaccharide polysulfate (Xylitol) ointment and sodium heparin ointment can be used to promote local blood circulation and enhance moisturization. If the surface is broken, it is recommended to use mupirocin ointment or fusidic acid ointment first to prevent local infection, twice a day. If you have the conditions, you can buy a humidifier, which is good for repairing the skin barrier, without using soap and body wash and without baking fire. Proper massage of the local skin is also beneficial. According to the above program, frostbite can be effectively relieved, but the disease can damage tissues and has a certain memory, so you must pay attention to good protection every year.
