Birthmarks are visible skin markings that are present at birth or develop shortly afterward. They occur when pigment cells, blood vessels, or other skin structures develop differently during early growth. While many birthmarks are harmless, some may change over time, become more noticeable as a child grows, or affect nearby tissues depending on their size and location.
At McKinnon Plastic Surgery, evaluation and treatment of birthmarks is performed by Dr. McKay McKinnon, a plastic surgeon with extensive experience in reconstructive and craniofacial surgery. Dr. McKinnon trained on the Harvard Surgical Service and later completed his plastic surgery residency at the University of Miami, where he developed specialized expertise in complex facial and soft tissue reconstruction.

What Are Birthmarks?
Birthmarks are areas of skin that differ in color or texture from the surrounding tissue. They may appear as flat discolorations, raised lesions, or areas of increased pigmentation.
Some birthmarks are present at birth, while others develop during early infancy. In many cases, birthmarks remain stable and require no treatment. However, certain birthmarks may enlarge, change in appearance, or affect surrounding structures, particularly when located on the face or neck.
Evaluation by a specialist can help determine the type of birthmark and whether treatment may be appropriate.
Common Types Of Birthmarks
Birthmarks are generally divided into two main categories based on the underlying cause.
Pigmented Birthmarks
Pigmented birthmarks occur when pigment-producing cells in the skin develop in higher concentrations. Examples include congenital nevi and café-au-lait spots.
Vascular Birthmarks
Vascular birthmarks develop when blood vessels form abnormally within the skin. These may appear red, purple, or blue and can vary in size and depth.
The behavior and treatment considerations for birthmarks depend on the specific type and location.
When Should A Birthmark Be Evaluated?
Most birthmarks are harmless, but medical evaluation may be recommended in certain situations.
Evaluation may be appropriate if a birthmark:
- Changes in size, color, or texture
- Continues to grow over time
- Causes discomfort or bleeding
- Interferes with nearby structures such as the eyes or mouth
- Raises cosmetic or functional concerns
Accurate diagnosis helps determine whether monitoring or treatment is the most appropriate course.
Surgical Treatment For Birthmarks
In some cases, surgical treatment may be recommended to remove or improve the appearance of a birthmark. This may be considered when a birthmark causes functional concerns, continues to enlarge, or significantly affects surrounding tissues.
Surgical techniques focus on carefully removing the affected tissue while preserving healthy surrounding skin. The approach depends on the size, depth, and location of the birthmark.
Because birthmarks often occur in visible areas such as the face or scalp, careful planning is essential to achieve the best possible cosmetic and structural outcome.
