After the joy of parenting, new mothers often find that their babies have various birthmarks of one kind or another on their skin. Old people often say, “Birthmarks, they are carried in the fetus and do not need to be treated.” Thus, some conditions are delayed. People often say there are many kinds of birthmarks, red, black, cyan, coffee, large and small, fast growing and slow growing, huge harm and fade away. Obviously, it is unreasonable to make a generalization about all kinds of birthmarks. Therefore, it is especially important to seek medical attention in time. Parents should visit a hospital in time for diagnosis when they find various birthmarks at an early stage. Some diseases, such as nevus, generally require early treatment; while strawberry hemangioma generally requires dynamic observation of the child’s condition and timely treatment before the growth of the hemangioma occurs; if degeneration has already occurred, we should choose the right time for treatment or wait according to the location. The timing of treatment and treatment plan need to be determined by an experienced dermatologist.
