What does the lunula represent?

The lunula, which is the small, crescent-shaped area at the base of the nail, represents the visible part of the nail matrix. The matrix is the tissue located beneath the base of the nail that produces new nail cells. As these new cells are created, they push older cells forward, which form the visible nail plate. The lunula is essentially the portion of the matrix that is not completely covered by the skin, making it visible on the surface of the nail. This area is often lighter in color than the rest of the nail due to its thickness and the underlying tissue structure.

Understanding the structure of the nail, including the lunula, is crucial in cosmetology for proper nail care and identifying potential nail health issues.
