Step-by-step explanation:
Excoriated skin is abnormal to find on an adult. Excoriation refers to the act of scratching or picking at the skin, leading to open wounds or sores. It is often seen in individuals with certain mental health conditions, such as dermatillomania (skin picking disorder), or those who engage in self-harm behaviors. If you or someone you know is experiencing excoriated skin, it is important to seek medical help and support.
