What does a first-degree burn typically involve?

A first-degree burn typically involves only the epidermis, which is the outermost layer of skin. This type of burn is characterized by redness, minor swelling, and pain without blisters. The skin may be dry, and there is usually no damage to deeper layers since only the epidermis is affected. This contrasts with more severe burns, which can involve deeper layers of skin, including the dermis, leading to increased symptoms and complications such as blistering or scarring. Understanding the classification of burns is crucial for appropriate treatment and management of skin injuries.
