When it comes to your baby’s skin, spotting a mole might raise some questions. Moles, or congenital pigmented nevi, are often harmless and can appear in various shapes and sizes. While they are more commonly found in older children and adults, a mole on a baby can be surprising. Understanding what these marks are and their implications is essential for any parent.

What Are Moles?

Moles are clusters of pigmented cells that typically present as brown or freckle-like spots on the skin. They can vary in color, with shades of pink, red, or black. Some may even have hair or appear raised and textured. Most moles are acquired over time due to sun exposure, which is why it’s critical to use sunscreen on your baby. The American Academy of Pediatrics recommends applying small amounts of baby-safe sunscreen with SPF 30 to 50 to infants under six months, while those six months and older should have sunscreen applied to all exposed skin.

Where Do Moles Typically Appear on Infants?

Moles can develop anywhere on your baby’s body, often appearing on areas frequently exposed to sunlight. However, congenital moles can also be present at birth.

What Causes Moles?

Moles are primarily caused by genetic factors and sun exposure. The pigmentation occurs as a result of melanocytes, the cells responsible for skin color, clustering together. While most are harmless, it’s wise to monitor any changes.

Do Moles Disappear?

In many cases, moles present at birth will remain throughout life. Some may fade over time, but it’s less common for them to disappear entirely.

When Should You Consult Your Baby’s Doctor About Moles?

If you notice any changes in your baby’s mole—such as growth, color change, or irregular edges—it’s important to reach out to a pediatrician. They can provide guidance and determine if further examination is necessary.
