Noticing thin vertical lines running from the base of your fingernails toward the tips can be surprising, especially when they seem to appear more clearly with age. Many people begin to observe these changes after turning 40, and in most cases, they are completely normal.
Vertical nail ridges are usually a reflection of natural aging rather than a sign of illness. Just as skin develops fine lines and hair texture evolves over time, nails also change as the body matures. While these ridges are often harmless, understanding why they form can help you care for your nails and stay attentive to your overall well-being.
