Many babies have a flat, pink or red mark on their forehead, which is often a type of birthmark called a nevus simplex.
Here's a more detailed explanation:
-
Nevus Simplex: This is the most common reason for a mark on a baby's forehead. These are sometimes called "stork bites" (if on the back of the neck) or "angel's kisses" (if on the forehead or eyelids).
-
What it is: A nevus simplex is a collection of small, dilated blood vessels (capillaries) near the surface of the skin.
-
Prevalence: Up to 80% of newborns have these marks.
-
Location: While common on the forehead, they can also appear on the eyelids, the back of the neck, the top of the head, under the nose, and on the lower back.
-
Appearance: They are usually flat and can range in color from pink to red. The color may become more pronounced when the baby cries or gets warm.
-
Why it happens: The exact cause isn't always known, but it is believed to be due to a slight delay in the maturation of these blood vessels in the skin.
-
Prognosis: Good news! Most nevus simplex marks fade significantly or disappear entirely within the first year or two of life. Marks on the nape of the neck may persist longer.
In summary, a mark on a baby's forehead is frequently a harmless nevus simplex, a common birthmark that usually fades over time. If you have any concerns about a mark on your baby's skin, consult with your pediatrician.
