What Causes Angel Kisses Birthmarks on Babies?

“Angel kisses,” also known as nevus simplex or salmon patches, are common, harmless birthmarks seen on many newborns. These gentle pink or reddish marks are benign vascular formations. They do not indicate any underlying health issues or complications for the baby, and are simply a common and reassuring part of early infancy.

Characteristics and Formation

These marks appear as flat, light pink, red, or sometimes purplish patches on a baby’s skin. Angel kisses are frequently found on the forehead, between the eyebrows, on the eyelids, nose, or upper lip. Another common location is the back of the neck, where they are often referred to as “stork bites.” These birthmarks are present at birth or emerge very shortly afterward.

The appearance of angel kisses results from the localized widening, or dilation, of tiny blood vessels called capillaries, which are located very close to the skin’s surface. This expansion of capillaries makes them more visible through an infant’s delicate skin. These marks are not caused by any form of trauma during birth or any external factors. Instead, they represent a minor variation in normal skin development.

Distinguishing from Other Birthmarks

Angel kisses differ from other types of birthmarks, such as hemangiomas or port-wine stains. Unlike hemangiomas, which are raised and often grow, angel kisses remain flat and do not protrude from the skin. They also differ from port-wine stains, which are typically darker, larger, and usually permanent without medical intervention. These marks pose no health risks to the child. Parents should consult a pediatrician if uncertain about any birthmark.

Fading and Management

Angel kisses tend to fade over time. Those on the face, such as on the forehead or eyelids, often become lighter or disappear within the first one to two years. This fading occurs as the baby’s skin thickens and the dilated capillaries become less prominent. Marks on the back of the neck tend to persist into adulthood, though they are usually covered by hair and are not a cosmetic concern.

No medical treatment is typically required for angel kisses, as they tend to fade on their own. Their appearance might become more noticeable when a baby cries, experiences changes in body temperature, or exerts themselves. This temporary darkening occurs as increased blood flow makes the capillaries more prominent. Such fluctuations are a normal characteristic of these birthmarks.
