If you cut the nail tip back too far, which part could it damage?

Cutting the nail tip back too far can damage the nail bed. The nail bed is the area of skin beneath the nail plate that provides support and nourishment to the nail as it grows. When the nail is cut too short, especially when the edge of the nail is trimmed excessively close to the skin, it can lead to discomfort and expose the sensitive nail bed, potentially causing pain and increasing the risk of infection.

The other options, such as the matrix, cuticle, and hyponychium, are areas involved in nail growth and protection, but the nail bed is directly affected when excessive trimming happens. Damage to the matrix, where new nail growth occurs, might not be immediately evident, while the cuticle protects the area at the base of the nail and the hyponychium is the skin under the free edge of the nail. However, the most immediate impact of cutting the nail tip too short is on the nail bed.
