Whether daily disinfection is necessary after a burn depends on the condition of the burn. If it is a minor burn with only superficial reddening, it is not necessary to disinfect daily after the initial treatment on the first day. If the burn is more severe and blisters have formed, it is recommended to disinfect daily, apply burn ointment, and cover with a dressing to prevent infection. Additionally, it is advised to drink plenty of water, eat fresh vegetables and fruits, consume high-protein and nutritious foods to promote healing of the burn, and avoid spicy and irritating foods.

Scalding that causes the skin to peel off is classified as a second-degree burn.

Burns that result in skin peeling must be examined case by case, as it is impossible to generalize. The classification depends on the size of the burn and the severity of the injury. If the burn only results in peeling skin, indicating damage to the epidermis, it is considered a superficial second-degree burn. If the damage extends below the dermis, it is considered a deep second-degree burn. If there is damage to deeper tissues, it could potentially be a third-degree burn. Furthermore, if the area of skin peeling due to the burn is extensive, it may be considered deep second-degree or more severe. Therefore, immediate actions should be taken following a burn, such as rinsing with cold water for at least 30 minutes or until the pain subsides. Then, thoroughly disinfect the area with iodine to prevent infection. Applying burn ointment on the surface may help in the recovery of the burn. If necessary, cover it with a sterile gauze to prevent contact infections that could lead to skin infection. Attention should also be paid to diet; drink plenty of water, eat fresh vegetables and fruits, consume high-protein and high-nutrient foods, supplement with vitamins, and avoid spicy and stimulating foods.

Will a burn leave a scar?

Whether burns leave scars depends on the severity of the burn and whether emergency measures were taken after the burn. Clinically, burns can be divided into three degrees. A first-degree burn, which is mild, generally shows symptoms such as stinging pain, mild swelling, and erythema. With timely soaking in cold water, rinsing, and application of burn medicine, scars are not left. For deeper second-degree and third-degree burns that involve the dermis, there is a possibility of scarring. At this point, the skin at the affected area may show necrosis, and local healing may be delayed. Therefore, actively treating the burn immediately after it occurs, preventing infection, and quicker wound healing can reduce the likelihood of scarring.

What should I do if I get a burn on my face?

If a burn occurs on the face, first rinse the burned area with running tap water or immerse the burned part of the face in a basin of tap water to promptly reduce the temperature of the burn site and lessen heat damage to the deeper tissues. Be sure the water is not too cold and generally rinse or soak for about 30 minutes, until the pain at the wound site significantly eases, and then rinsing or soaking may be discontinued. After rinsing or soaking in cool water, observe the burned area. If the burn site is slightly purple and red, you can apply some burn ointment at home. If there are obvious blisters or the skin is broken, protect the burn site with a clean towel and go to the nearest hospital burn department for professional medical treatment quickly. Be sure to protect the blisters on the burn site to avoid bursting them.

How many days do I need to apply ointment for a burn on my finger?

The duration of applying medication for a finger burn depends on the severity of the burn. If the burn is minor, medication is generally applied for two to three days until the pain is not significant, and then it may no longer be necessary to apply medication, as mild burns only affect the epidermis and relief from pain is sufficient. If the burn is more severe, medication may need to be applied for a longer period. Therefore, it is crucial to immediately rinse the burn under running water for at least half an hour to cool it down and minimize further progression of the burn. This action is beneficial for recovery. Additionally, if the burn is quite severe, it is advisable to seek prompt medical treatment at a hospital.

Should blisters from burns be punctured?

Whether to prick a blister caused by a burn depends on the size of the blister. For smaller, dense blisters, it's generally not necessary to break them, as the fluid can be absorbed naturally. However, it's important to keep the wound clean to avoid secondary injury, and topical burn ointment can be applied. For larger blisters caused by burns, or those with high tension that interfere with daily activities or life, and are difficult to absorb, you can sterilize the area and then use a sterile needle to puncture the base of the blister to drain the fluid. Be sure to thoroughly clean out the fluid inside the blister. However, the blister skin should be kept intact to cover the skin, providing protection, reducing the risk of infection, and promoting recovery.
