Birthmarks are visible skin changes that either appear at birth or within the first few weeks of life. They can differ in shape, size, and colour, and may be either flat or raised. While most are harmless and gradually fade, some may remain long term and require treatment for aesthetic reasons or due to related symptoms or health risks.
