Port Wine Stains

A PWS is a birthmark with an increased number of swollen blood vessels that create a reddish-purple discoloration of the skin. They are named for a type of dark red wine called port. These birthmarks are often found on the face but can happen anywhere on the body.

These birthmarks do not fade away. They grow as your child grows. Sometimes, they can look darker or get thicker as your child gets older.

PWSs are usually not related to other health problems, but in a small number of children, they can be associated with brain or eye problems. Your healthcare provider can talk with you about these problems in more detail if it affects your child.

The goal of treatment is to minimize the appearance of redness on the skin.

Pulsed dye laser therapy works well for many PWSs. It helps to lighten the color and prevent darkening and thickening that sometimes happens over time.

This treatment often works better on the face and neck, rather than on the arms and legs. The laser works better for lighter port wine stains, but the darker purple marks can also be treated. It is suspected, but still unknown, if treating at an earlier age (before 1 year) can lead to better outcomes.

Camouflage or full coverage make-up like Covermark, Dermablend, Dermacol or Focallure Covermax can help hide the appearance of a PWS. They are available at department stores, WalMart and at online stores.
