Hello, I'm a specialist in genetics and medical science. When it comes to birthmarks, it's important to understand that they are typically developmental in nature and can have various causes. Let's delve into the question of whether birthmarks are hereditary.
Birthmarks are generally classified into two main types: vascular and pigmented. Vascular birthmarks are caused by the presence of extra blood vessels, while pigmented birthmarks are due to an excess of pigment-producing cells called melanocytes.
The development of some types of birthmarks has been associated with genetic factors. For example, certain conditions like Sturge-Weber syndrome or Klippel-Trenaunay syndrome are known to have a genetic component and can be associated with vascular birthmarks. However, having a genetic predisposition does not guarantee that a birthmark will develop, as environmental factors and random events during fetal development can also play a role.
On the other hand, many common birthmarks, such as salmon patches (nevus simplex) or moles (nevi), are not typically considered hereditary. They are quite common in newborns and usually fade over time without any intervention.
In conclusion, while some birthmarks may have a genetic component, it is not accurate to say that all birthmarks are hereditary. The inheritance of birthmarks is complex and can involve a combination of genetic and environmental factors.

Birthmark. A birthmark is a congenital, benign irregularity on the skin which is present at birth or appears shortly after birth, usually in the first month. They can occur anywhere on the skin. ... In addition, it is known that vascular birthmarks are not hereditary.
