While hydrogen peroxide is a common household antiseptic, it should not be used on burns. Hydrogen peroxide can damage healthy tissue and delay the healing process. Additionally, the bubbles can dislodge any scabs that have formed, increasing the risk of infection.

It is important to avoid putting anything other than cool water or a sterile saline solution on a burn. If the burn is severe or covers a large area, it's important to seek immediate medical attention.
