The type of burn that only affects the outer layer of skin, comparable to a sunburn and without blistering, is indeed classified as a first-degree burn. First-degree burns involve the epidermis, which is the outermost layer of skin. This kind of burn typically results in redness, swelling, and mild pain but does not extend beyond the epidermis, so there are no blisters present. The skin may feel warm to the touch, and the healing process usually occurs within a few days without significant intervention.

In terms of severity, second-degree burns impact both the outer layer and the underlying layer of skin (the dermis), leading to blisters and more intense pain. Third-degree burns penetrate deeper, damaging both the epidermis and dermis, and can affect other tissues, often resulting in charring or a leathery texture. Chemical burns arise from exposure to harmful chemicals and can vary in severity, encompassing first, second, or third-degree characteristics depending on the chemical and exposure duration. Understanding these distinctions is essential for providing appropriate first aid and treatment based on the specific type of burn involved.
