Nail Lines: Harmless or a Sign of Health Issues?
What Vertical Ridges on Your Nails Really Mean
Vertical ridges on the fingernails are something many people begin to notice as they move into their 40s and beyond. These raised or indented lines run from the base of the nail all the way to the tip and can appear deeper or more defined with age. For most individuals, this change is completely normal. It reflects the natural slowing of nail cell turnover and the gradual reduction in moisture and oil production that occurs as part of the aging process. When the nail grows more slowly, the surface may appear less smooth, causing ridges to stand out more clearly.
