What is known as the stress area of the nail?

The stress area of the nail refers to the portion where the natural nail extends beyond the finger, which is commonly known as the free edge. This area is significant because it is the most vulnerable part of the nail, as it is prone to chipping and breaking due to daily activities. Understanding this aspect is crucial for nail care and maintenance, especially when applying enhancements or nail extensions. The stress area requires careful attention during manicure services to ensure durability and longevity of the nail.

In terms of the other options, the matrix of the nail is located beneath the base of the nail and is responsible for nail growth, while the cuticle area is the skin surrounding the base of the nail that protects the area where the nail grows. Both of these areas serve different functions that are important for nail health but do not specifically refer to the stress area where the nail is most likely to experience wear and tear.
