What is the difference between partial and full-thickness burns?

Partial-thickness burns affect the outer layer of skin (epidermis) and extend into the underlying layer (dermis), resulting in pain, swelling, and blistering. Full-thickness burns, on the other hand, penetrate through both the epidermis and dermis, potentially damaging deeper tissues, including fat, muscle, and bone, leading to a loss of sensation in the affected area due to nerve damage. Partial-thickness burns typically heal more quickly and can often be treated with conservative care, whereas full-thickness burns usually require more intensive medical intervention, including possible surgery and skin grafting.
