Hi,

Hi,

The two main types of birthmarks are red, vascular birthmarks which includes strawberry hemangiomas, port-wine stains, and "stork bites";  and pigmented birthmarks such as moles, café-au-lait spots, and Mongolian spots. They are mostly harmless and many even go away on their own or shrink over time. In particular,  a port-wine stain is a flat, pale pink, bright red or bluish-purple birthmark that can occur anywhere on the skin, but is most common on the face. It is usually present at birth and can continue throughout life. If it does not go away,  it is sometimes treated with laser therapy or cosmetics. Port-wine stains are harmless but may also be associated with other syndromes. It is best to discuss this with your doctor to rule out such causes.

Take care and regards.
