I have many moles – what is behind them?
There are factors that favour the appearance of birthmarks. On the one hand, there are hereditary factors, the skin type and the pigment melanin. Scientists assume that the probability to get numerous birthmarks itself is the more frequent, the more frequently birthmarks occur in the relationship.
In addition, light skin types generally have more moles than dark skin types. A light skin type and many moles in the family favour the occurrence of moles. A clear cause is not known.
