Question: How does birthmarks form?


  1. There are two types of birthmarks – one is where you have a darker patch of skin, and that’s caused by an excess of skin pigment cells. The other type, which is more of a red patch is caused by an increase in the blood vessels in the area.

    I have a birthmark on my arm – people always say “why is one arm more tanned than the other?” – it does look like I have a bit of a permanent tan on one arm! 😀
