Port Wine Stains

Causes & Symptoms

A port wine stain is appears as a red/pink birthmark that present from birth and are common among newborns and are caused by tiny blood capillaries in the skin.Although it is rarely harmful, it can highly impact an individual’s confidence and self esteem. This condition gets its name due to the colour the birthmark makes the skin. Unfortunately, they rarely fade, however they are not signs of any major health problem.

There is no known cause for this condition, and you cannot prevent them from happening as it relates to chemical signals in the blood vessels. Furthermore, if an individual has port wine stains on their face or around their eyes it can have serious consequences such as seizures or eye problems. This can lead to problems such as glaucoma, which can lead to blindness. Therefore if this is the case, we highly recommend you to see one of our dermatologists.

Treatment at The Skin Hospital

Unlike other birthmarks, port wine stains grow as a child grows, continuing and lasting into adulthood. Not only does the stain get bigger, but the colour can also get darker as well as the skin’s texture changing slightly, becoming thicker than the rest of the skin. Furthermore, the skin can also change from a smooth texture into an almost ‘pebbly’ feel.

The affected area shouldn’t itch, hurt or bleed. If this is the case then you should consult your doctor straight away as they will be able to let you know if there are any problems.

The preferred treatment for this condition is pulsed dye lasers (PDL). This has proven to have a high success rate and lighten the colour of the affected area significantly. However, in some PDL is ineffective and patients will need further consultation and possible other laser treatments.
