Why Do They Appear With Age?

As we age, our bodies produce less of certain natural oils and proteins, including keratin, which is essential for strong, smooth nails. This decrease can cause the nail plate to become thinner and less hydrated, leading to visible ridges.

In addition, blood circulation may slow down slightly with age, which can affect how nutrients are delivered to the nail matrix (the area where nails grow). This can result in subtle texture changes, including vertical lines.
