Usually, partial-thickness burns heal in 10 days to 2 weeks. Large burns may take 3 to 4 weeks to heal. There may be little or no scarring if the burn was not too extensive and if infection is prevented. Do remember that blistering sunburns can cause skin cancer (melanoma) later in life.
Similarly one may ask, how do you treat a burn blister?
For minor burns:
- Cool the burn.
- Remove rings or other tight items from the burned area.
- Don't break blisters.
- Apply lotion.
- Bandage the burn.
- If needed, take an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve) or acetaminophen (Tylenol, others).
Why does the skin blister when it's burned?
A blister may form when the skin has been damaged by friction or rubbing, heat, cold or chemical exposure. Fluid collects between the epidermis—the upper layer of the skin—and the layers below. This fluid cushions the tissue underneath, protecting it from further damage and allowing it to heal.
