As a dermatologist with extensive experience in skin conditions, I can explain that a white birthmark, also known as a vitiligo macule or nevus depigmentosus, is a condition where there is a loss of melanocytes, which are the cells responsible for producing the pigment melanin that gives color to our skin, hair, and eyes.
Several factors can contribute to the development of a white birthmark:
1. Genetics: There may be a hereditary component to vitiligo, as it can run in families.
2. Autoimmune Response: The body's immune system may mistakenly attack and destroy melanocytes.
3. Nervous System: Some theories suggest that chemicals from the nervous system could affect melanocytes.
4. Oxidative Stress: An imbalance in the body's production of free radicals and antioxidants can lead to damage to melanocytes.
5. Environmental Factors: Certain chemicals or physical trauma to the skin may trigger depigmentation in some individuals.
It's important to note that not all white marks are birthmarks; they can also be a result of other conditions such as tinea versicolor or scleroderma. A proper diagnosis by a dermatologist is essential for determining the cause and appropriate treatment.

While far less commonly noted at birth than red birthmarks, white birthmarks can appear as white spots in a raised or flat pattern on the skin. Dr. Friedlander noted that although white birthmarks are generally harmless, they can sometimes result in a permanent loss of pigmentation in the affected area.
