Hi,
The gold standard for port-wine stain treatment is the 585-595nm pulsed dye laser which targets the superficial blood vessels and helps clear the port-wine stain with minimal risk of scarring. Early treatment gives the best results.
Unfortunately, this special laser is not commonly available except in a few hospitals and laser clinics. I suggest that you see a laser dermatologist at the National Skin Centre for further evaluation.
Hope this helps!
