Hi there. I have a port wine stain on my leg (mid thigh/above my knee). I'm 32 now but started pulse dye laser treatments when I was around 12. I've had around 15-20 all together and it is still there but much smaller. It was around the size of a deck of cards and now it s half that size and much lighter. We were told back then that PWS's on the lower portion of the body are a bit harder to remove. I don't know if it is becuase the blood vessels are more dense or what. It's been many years since I've had a treatment so I'm sure the lasers are much better now than they were back then. It was new technology when we started my treatment.
I'm sure if I went back for a few more treatments it would be gone!
Good luck and have faith!!
