How many levels of burns are there?

The correct answer indicates that there are four levels of burns, which is fundamental in understanding the severity and treatment required for burn injuries. The four levels are classified based on the depth of skin damage and the associated symptoms:

1. First-degree burns affect only the outer layer of the skin (epidermis), causing redness, minor swelling, and pain, similar to a sunburn.
2. Second-degree burns involve both the epidermis and the second layer of skin (dermis). They can cause blisters, severe pain, and swelling.
3. Third-degree burns penetrate through the skin to deeper tissues, leading to white or charred skin and numbness due to nerve damage.
4. Fourth-degree burns extend beyond the skin into muscle and bone, resulting in severe damage, loss of function, and often necessitating surgical intervention.

Recognizing these four levels of burns is critical for accurate assessment, appropriate medical response, and effective treatment protocols in esthetic practices and beyond.
