What behavior can lead to an excoriation?

1. Nail biting

2. Excessive tanning

3. Frequent washing of hands

4. Overuse of skin creams

The correct answer is: Nail biting

Nail biting is a behavior that can lead to an excoriation, which refers to the damage or eroding of the skin surface, often caused by excessive scratching or picking. When individuals bite their nails, they may inadvertently cause injury to the surrounding skin or even the nail bed itself, leading to open wounds or infections. Additionally, the consistent trauma from nail biting can create a cycle of irritation and further damage, leading to noticeable excoriations. The other behaviors listed, while they may have their own consequences, do not directly cause skin excoriation in the same manner. Excessive tanning can lead to skin damage or increase the risk of skin conditions but does not involve the same kind of physical abrasion as nail biting. Frequent washing of hands can result in dryness or irritation but is typically not associated with actual skin damage to the extent of excoriation. Similarly, overuse of skin creams can cause skin issues or irritation but does not lead to excoriations directly unless a specific allergic reaction or adverse reaction occurs. Therefore, nail biting is the most relevant behavior linked to the development of excoriations.
