So I have a port wine stain on my face and neck. I started treatments when I was 3 weeks old. I switched doctors at 5 years old due to no change and scaring left from the doctor. I was with the second Doctor till I was 16. My birthmark would fade and come back but never gone. I was told it would be gone at 5, then at 12 and then sometime after 16 but there was never any signs of improvement....
