(1) Whether a burn will develop into a white spot depends on the severity of the burn and the healing process. Pigmentation changes may occur during the healing process of a burn, but they are usually not white spots. If you are concerned about pigmentation changes or have other skin problems after a burn, you should consult your doctor or a specialized dermatologist for evaluation and treatment.

(2) When hot oil is accidentally splashed on your arm while sautéing, if it burns and blisters, this usually means that the skin has suffered some degree of thermal injury. This injury may be a first-degree burn or a second-degree burn. First degree burns usually only injure the superficial layers of the skin, causing damage to the nerve tissue under the skin, which may cause painful sensations but no permanent scarring . However, if the burn is deeper, blisters may form, a condition that requires more careful treatment.

The proper initial treatment of a burn includes the following steps:

1. Cool the burn: Immediately rinse the burned area with running cold water for about 30 minutes to minimize further tissue damage from the heat and to help relieve pain .

2. Gently Remove Clothing: While rinsing with cold water, gently remove as much clothing as possible from the wound. If clothing is adhering to the wound, it can be carefully cut with scissors to avoid damaging the blisters.

3. Soak the wound: If possible, soak the burned area in cold water for 10 to 30 minutes to further relieve pain and distribute heat.

4. Protect the wound: Use sterile gauze or clean cloth to gently cover the wound to avoid infection.

5. Avoid using grease or ointments: Do not apply substances such as grease, toothpaste, butter, etc. to the burned area, which may aggravate the burn or cause infection.

6. Observe the injury: If the burn is serious, such as large blisters or severe pain, you should seek medical attention.
