The rounded shadows at the base of your nails are called fingernail moons, or lunula in Latin. The lunula is part of the matrix, the place where each nail begins growing. The visibility of the lunula can vary depending on skin colour and other factors, and its absence doesn't always indicate a health problem. However, in some cases, it can be a sign of vitamin deficiency, kidney failure, or another health condition.

The lunula is the visible portion of the matrix, the pocket under the skin where nails grow. The matrix contains nerves, lymph, and blood vessels, and produces the cells that become the hardened nail plate.

The absence of a lunula can indicate a vitamin deficiency, vitiligo, kidney failure, or another health condition. It can also be a sign of anemia, malnutrition, and depression.
