To treat matchstick burns hold the burned skin under some cool but not cold running water or you can also immerse the burned skin in some cool water until the pain subsides.
If running water is not available you can apply a cool compress to the matchstick burns.
Don't use very cold water or ice as it can damage the skin further and make the burn worse.
After you do cool the matchstick burn, you should gently pat the skin dry and cover the burned skin with a clean and sterile bandage.
You can also take some acetaminophen or ibuprofen to manage the pain and swelling.
After cooling the matchstick burn you should also gently clean the area using some mild soap and water but avoid scrubbing.
If the matchstick burn is severe or covers a large area or there's signs of infection like redness, pus or increased pain you should seek medical attention.
Most match burns and small skin burns and first or second degree burns often heal within 1 week to 2 weeks and usually don't cause any scar.
In some people with second degree burns the skin might become lighter in color or darker in color, although it will return to normal after 6 to 9 months.
