First-degree burns cause minimal skin damage. They are also called “superficial burns” because they affect the outermost layer of skin. Signs of a first-degree burn include:
redness
minor inflammation, or swelling
pain
dry, peeling skin occurs as the burn heals
Since this burn affects the top layer of skin, the signs and symptoms disappear once the skin cells shed. First-degree burns usually heal within 7 to 10 days without scarring.
You should still see your doctor if the burn affects a large area of skin, more than three inches, and if it’s on your face or a major joint, which include:
knee
ankle
foot
spine
shoulder
elbow
forearm
First-degree burns are usually treated with home care. Healing time may be quicker the sooner you treat the burn. Treatments for a first-degree burn include:
soaking the wound in cool water for five minutes or longer
taking acetaminophen or ibuprofen for pain relief
applying lidocaine (an anesthetic) with aloe vera gel or cream to soothe the skin
using an antibiotic ointment and loose gauze to protect the affected area
Make sure you don’t use ice, as this may make the damage worse. Never apply cotton balls to a burn because the small fibers can stick to the injury and increase the risk of infection. Also, avoid home remedies like butter and eggs as these are not proven to be effective.
