What should you know about port wine skin condition?

The patch results from small blood vessels that are wider than usual near the skin surface. It is generally present from birth and does not spread by contact. Colour can range from pink to deep red or purple. The condition itself is not an infection. With time, some patches become darker, thicker, or more uneven, which is why changes in appearance should be recorded and reviewed.

A dermatologist can confirm the diagnosis by examining the patch and asking when it appeared and whether it has changed. Keep the skin moisturised, protect it from strong sun, and avoid rubbing or injuring raised areas. If the appearance affects confidence or daily life, ask about vascular laser options, including pulsed dye laser treatment. Treatment choice depends on the location, colour, texture, and your skin tone.

See [Pulsed Dye Laser Treatment](/treatments/laser-and-energy/pulsed-dye-laser-treatment/) for an overview of this approach.

Arrange medical review for a new nodule, a sore that does not heal, repeated bleeding, sudden colour change, or increasing tenderness. Get urgent help for rapidly spreading redness, severe swelling, fever, or an eye or neurological symptom. These signs need assessment on their own and should not be explained away by the birthmark.

Ask whether the patch has typical features of a capillary malformation, whether its texture needs monitoring, and which changes should prompt review. You can also ask about treatment goals, healing time, pigment changes, and ways to protect the area during outdoor activities.
