Hi Maria, thank you for the question.

Your best approach would be to consult a dermatologist who can examine the birthmark and advise you on the best treatment option.

From your description this sounds like a Port Wine Stain which is a birthmark classified by a large collection of blood vessels.

Port-wine stain is also known as naevus flammeus. Specifically, it is a vascular malformation, which means it is a birthmark made of enlarged capillaries in the skin. Capillaries are tiny blood vessels in the body that connect the arteries and veins together. They are normally small and tiny. With enlarged capillaries, port-wine stain produces a red to purple discolouration of the skin. Port wine stain appears as a flat birthmark, ranging from light pink to deep purple in colour. It usually grows proportionately with age and become extremely unsightly in some cases. The lesion may become raised or bumpy as the patient achieves puberty and later in life, the surface may become bumpy and uneven, and it may bleed easily.

Currently, laser therapy called the pulsed dye laser (PDL) is used to treat port-wine stains cosmetically, as there is no "cure". There are studies confirming its effectiveness in adults, children and infants with low side effects. Hence, PDL is currently the first-line treatment for port-wine stain.
