The rounded shadows at the base of your nails are called fingernail moons or lunulae (the Latin for 'little moon'). The lunula is part of the nail matrix, the tissue just beneath your nail that produces the cells that become the hardened nail plate. The lunula's location on the newest part of the nail means that its appearance can provide clues about a person's health. For example, red lunulae can indicate a number of conditions that may significantly affect your health.

In some cases, the absence of lunulae may indicate an underlying health problem.

If you are concerned about the absence of lunulae, it is a good idea to discuss the issue with a doctor. They can assess your health and determine if there is an underlying problem.
