Birthmarks may be of different types.The pigmented mole may or may not have a hair growth.Excision removes this, or freezing with dry ice once a week will dry it up and it will peel off.
If the mole is rough, pigmented and wartlike, it should have a doctor's attention.Birthmarks of the vascular type seem like patches on the skin, of varying sizes, and have a purple wine color or a pink shade.
The exact coloration depends on whether it is made up of small veins or arteries. The pink sometimes disappears as the child grows older. The purple lasts throughout life.
Small birthmarks may be removed by surgery.Larger ones are sometimes removed successfully by electrolysis. Never trust to technicians, go to a reputable doctor
