Birthmarks can be patches of darker or lighter skin that you have had since birth. Some people are also born with moles. Skin Dermatology offers skin examinations to those concerned about their birthmarks or moles and looking for removal options.

Why Do Birthmarks Appear?

Right now, there is no conclusive answer on why birthmarks form. Stories of how birthmarks were caused during pregnancy are myths. A small percentage of birthmarks are hereditary, and genetic mutations cause even fewer.

What Are Moles?

Some people are born with moles, which are then considered birthmarks. A mole is a small skin growth that is typically brown. They can also be black, red, pink, or tan. Most moles are round or oval-shaped and can be flat or raised. Most moles are not dangerous, but it is important to monitor them as moles can become cancerous. If you notice any changes in a mole, Skin Dermatology performs skin examinations to determine if it is cancerous.

Can Birthmarks Appear After Birth?

Birthmarks can develop in the first few months after birth. Marks or growths that appear on the skin after that are not considered birthmarks. For example, moles can develop at any stage of life, but they would no longer be a birthmark.

Birthmark and Mole Removal 

While most birthmarks do not require removal, there are options for those looking to have a birthmark removed. 

Laser Treatments

Laser treatments can help lighten heavily pigmented marks or red patches such as port-wine stains. However, it may require several treatments to achieve the desired result. 


Corticosteroids help shrink the size of a birthmark. They are anti-inflammatory medications that can be taken orally or injected into birthmarks.


Surgery is also an option for certain types of birthmarks, including larger moles. Most often, a small scalpel is used for the removal process.
