Nail Ridges After 40: A Common But Overlooked Sign of Aging
As people age, they often notice changes in skin, hair, and joints—but fingernails also undergo transformation. One of the most common and visible changes after age 40 is the appearance of vertical lines or ridges on the nails.
These ridges, known medically as longitudinal striations, run from the base of the nail (near the cuticle) to the tip. While usually harmless, they can sometimes hint at deeper health or nutritional concerns.
