The science of birthmarks is not entirely understood, especially why they are prevalent in some newborns but not in others. However, there are several potential reasons for birthmarks:

- A few studies have shown that birthmarks might be due to a placental fragment embedded in the foetus during early gestation.

- Strawberry haemangiomas are thought to be caused by endothelial cells from the blood vessels accumulating in one spot.

- Port wine stains might be caused by extremely dilated capillaries, which in turn are a result of nerve damage.

- Research shows that salmon patches occur due to blood vessels concentrating under the skin.
