In your case, you have a minor burn on the upper lip, which has led to a protective ‘bump’ (blister) as the skin tries to heal itself. Chances are you will not experience much pain, though there may be some discomfort. In a few days, you will notice some clear liquid discharge from the blister; this is completely normal and shows that the skin is healing. You may get the urge to frequently tongue and ‘play’ with the bump. Go right ahead; saliva is naturally cooling and even has some healing abilities. However, under no circumstances should you try to pop the blister. This will damage the skin on your lip and may even lead to a pale spot or scar. Let nature take its course.
If you do feel discomfort or a burning sensation, apply a cold compress to your lip. A plastic bag or ice cubes or a packet of frozen peas will do nicely. Try soaking a clean cloth in milk of magnesia (plain milk will also do) and directly patting the affected spot. The fibers found on the inside of banana peels are also recommended, since they contain a natural emollient that softens the skin, reducing the swelling. Apply some aloe vera gel to the lip, since this natural wonder has excellent antibacterial properties that will help to avoid any secondary infections. Aloe vera also helps to speed up the natural healing process, and can prevent any scarring of the skin. Of course, you need to completely avoid very hot meals and spicy foods until the burn is healed. Stay away from alcohol and tobacco as well; these can delay the healing process. If the blister does not heal in a week, you may want to visit a doctor, since this could mean the burn is deeper and more serious.
