Why Vertical Lines on Your Nails Often Appear With Age
As we age, everything slows down—including nail production. The nail matrix doesn't produce keratin as efficiently, leading to uneven surfaces.
2. Changes in Cell Turnover
The rate at which new nail cells are produced and pushed forward becomes less consistent with age.
3. Decreased Moisture
Nails, like skin, become drier with age. This can make existing ridges more noticeable.
4. Cumulative Environmental Exposure
Decades of exposure to water, chemicals, and minor trauma can affect nail texture over time.
