How is the birthmark on the face formed

The first aspect: the main factors of the rising incidence of red birthmark depend on people's living habits, as well as environmental pollution, which lead to human genetic changes.

The second aspect: from the beginning of agricultural planting and sowing, a large number of pesticides and chemical fertilizers are used, until after harvest, every link of grain storage is sprayed with pesticides and stored.
