Detailed explanation-1: -First-degree burns affect only the outer layer of skin, the epidermis. The burn site is red, painful, dry, and has no blisters. Mild sunburn is an example.
Detailed explanation-2: -Third-degree burns affect all three skin layers: epidermis, dermis and fat. The burn also destroys hair follicles and sweat glands. Because third-degree burns damage nerve endings, you probably won’t feel pain in the area of the burn itself, rather adjacent to it.
Detailed explanation-3: -First-degree burns (superficial burns) are mild compared to other burns. They cause pain and reddening of the epidermis (outer layer of the skin). Second-degree burns (partial thickness burns) affect the epidermis and the dermis (lower layer of skin). They cause pain, redness, swelling, and blistering.
