Birth marks such as Port Wine Stain or Cafe Au lait can get ______ with age?

Birthmarks like Port Wine Stains or Café au Lait spots often change in appearance as a person ages. Port Wine Stains, a type of vascular malformation, can indeed become larger over time. This happens because the blood vessels that make up the stain can grow and become more pronounced as the skin changes with age. Additionally, the color can deepen due to various factors including the vascular nature of these birthmarks.

On the other hand, Café au Lait spots, which are flat, pigmented lesions, may not necessarily disappear or shrink significantly as a person gets older, though they might maintain their size or become slightly larger. Overall, it is common for these types of birthmarks to become more noticeable rather than smaller or less prominent with age, making the correct answer focus on them getting larger.
