How to treat blisters after a burn

Blistering after a burn can be managed through cooling, cleansing, protection, moisturizing, and observation.

First, immediately rinse the burned area with cool water to rapidly reduce skin temperature, alleviate pain, and prevent further injury. It is recommended to rinse for no less than 10 minutes. Gently wash the affected area with mild antibacterial soap and clean water. Avoid using irritating disinfectants such as alcohol or iodine, which may worsen skin damage.

Observe the size and location of the blister. If the blister is small, it may require no special treatment and can be left to be absorbed naturally. If the blister is large or located in areas prone to friction or infection, such as joints, further treatment is needed. Apply a thin layer of non-adhesive burn ointment or petroleum jelly, then cover with sterile gauze to keep the wound moist and promote healing.

Do not puncture the blister, as it serves as a natural protective barrier formed by the body and helps prevent infection. If the blister does rupture, gently wipe the area with sterile gauze and cover it to avoid friction and external contamination.

Keep the wound clean and dry, and avoid contact with water. Avoid excessive movement or friction at the wound site to prevent worsening the injury. If signs of infection such as redness, swelling, or increased pain occur, seek medical attention promptly.
