First of all welcome to the group.
I am a 24 year old with a facial port wine stain birthmark.
Being that you are 27 and that most Stork bite do go away on their own. I would consider maybe getting a second opinion. You could send a photo to Dr. Nelson (the ask the pws doctor on the front of this website) He works with several types of laser machines and treats every different kind of birthmarks.
I have used several lasers but neither of those two machines. I have also had three plastic surgeries. If you would like to see pictues you can see them on my website (www.hankspws.com
I hope this helps and hope to talk to you soon.
