Birthmarks are skin anomalies present at birth or developing shortly after, often appearing as coloured spots or patches. They vary in colour, size, shape, and texture, ranging from small brown or red spots to large, dark patches. The most common types are vascular birthmarks, like hemangiomas or port-wine stains, and pigmented birthmarks, such as moles or café-au-lait spots. While most birthmarks are harmless, some may be associated with other health conditions or become problematic due to their size or location. Treatment options depend on the birthmark type and its impact on the individual’s health or appearance. Options include laser therapy, surgical removal, or cryotherapy. For cosmetic reasons or health concerns, consulting a dermatologist can help determine the best course of action.
