Burns are classified into three types based on the depth and severity of tissue damage: - First-degree burns affect only the outer layer of the skin (epidermis) and cause redness and pain. - Second-degree burns affect both the epidermis and the underlying dermis, causing blisters, swelling, and severe pain. - Third-degree burns extend into deeper tissues, causing white or blackened, charred skin that may be numb due to nerve damage.
