Port Wine Stain is a term to describe a vascular birthmark. These birthmarks are red/purple in color because of the concentration of blood vessels near the surface of the skin that make up the birthmark. Because these blood vessels are superficial and are not needed, an effective treatment for the fading or resolution of port wine stain birthmarks is to close the superficial blood vessels using class IV medical lasers. For example, pulsed dye lasers are very precise in targeting the hemoglobin found in the blood vessels of port wine stain birthmarks.
The thermal/heating effect causes the small capillaries to close altogether or diminish from view. Port Wine Stain birthmarks are challenging to treat and may require up to 10 or 12 treatments; however, the use of Class IV medical lasers (pulsed dye lasers) is considered the “gold standard” for safe, effective treatment.
