Stork Bites and Angel Kisses: The Fading Birthmarks

Save

Nearly every newborn nursery sees at least one of these pink patches, and pediatricians consider them the most common vascular birthmark of infancy. Unlike a strawberry mark or a rash, a salmon patch doesn't grow and doesn't need treatment — its location on the face versus the neck predicts almost everything about whether it fades completely or stays as a faint, permanent feature.

What exactly is a stork bite or angel kiss?

A salmon patch is a flat, pink-to-red mark made of small dilated blood vessels sitting close to the surface of a newborn's skin — clinically called nevus simplex, though almost nobody outside a pediatrics office uses that name. Where it shows up gives it its folk names: a patch on the back of the neck, often hidden under hair, is the classic stork bite; a patch on the eyelids, the bridge of the nose, or the center of the forehead is called an angel kiss. Some babies have one, some have several, and some have none at all. It is present from birth, doesn't grow, and sits flush with the skin rather than raised above it. It is also blanchable — pressing a finger against it lightens the color, because it's made of ordinary capillaries near the surface, not new tissue growth. It is one of the most common findings on a newborn skin exam, and clinicians generally note it as a routine part of describing a healthy baby's skin rather than flag it as a concern.

Why does it get darker when the baby cries or gets warm?

A stork bite or angel kiss darkening during crying, straining, or a hot bath is normal and doesn't mean the mark is getting worse. the deeper color is temporary blood flow, not the birthmark spreading or growing. Crying and straining raise blood pressure in the small vessels near the skin's surface throughout the body, and a salmon patch — being nothing more than a cluster of those vessels — reddens along with everything else that flushes when a baby is upset, from the face to the chest. The same happens with overheating, a hot bath, or vigorous activity later in childhood. Once the baby calms down or cools off, the patch generally returns to its baseline color within minutes. Parents often notice this cycle for months before realizing it's simply how the mark responds to normal physiology, not a sign that needs a call to the pediatrician on its own.

How long before it fades, and does location predict the outcome?

Location is the best available predictor of whether a salmon patch fades or lingers. Angel kisses — the ones on the eyelids, forehead, and nose — tend to fade the most completely, and many are barely visible by a child's first or second birthday as the skin thickens and the underlying vessels recede. Stork bites at the nape of the neck behave differently: many persist for years, and it isn't unusual for an adult to still have a faint pink patch at the hairline that shows up more when they're overheated, flushed, or sunburned there. Neither pattern is a medical problem either way — a stork bite that never fully fades is a cosmetic footnote covered by hair, not a health concern. There's no treatment that reliably speeds up the fading process, since the mark lives in the blood vessels beneath the surface rather than in the skin itself. Patience, not product, is the standard approach for the marks expected to fade on their own.

Could a red mark be something other than a birthmark?

A vascular birthmark present since birth is different from a rash that develops afterward, and the distinction is usually straightforward once it's pointed out. A salmon patch is there from day one, sits in one of a handful of classic locations, and doesn't itch. A newly appearing red patch — say, around the mouth from drooling, or on the cheek after starting a new lotion or fabric softener — is more likely a form of contact dermatitis: an irritant or allergic skin reaction that tends to have less defined borders, causes itching or fussiness when touched, and clears up once whatever is irritating the skin is removed 1. The two are rarely confused by anyone who has seen both, but it's a fair question for a parent noticing a red mark for the first time and unsure whether it was there at birth or appeared later. In the uncommon case where a persistent red patch is suspected to be an allergic skin reaction rather than a simple irritant one, patch testing — applying small amounts of suspected allergens to the skin under observation — is the diagnostic method clinicians use to identify a specific trigger, though this is a tool used far more often in older children and adults than in newborns 2.

How does a salmon patch differ from other common newborn marks?

Several different newborn skin findings get grouped together in parents' minds as "birthmarks," but they come from different tissue and behave differently. The strawberry mark — an infantile hemangioma — starts flat or faint but typically grows and becomes raised over the first months of life before slowly fading over years; a salmon patch, by contrast, never grows and is flat from the start. A blue-gray birthmark, also called dermal melanocytosis, is a flat patch too, but it's usually slate-blue or gray rather than pink, most often sits on the lower back or buttocks rather than the face or neck, and comes from a different source entirely — melanocytes, the pigment-making cells, sitting deep in the skin rather than blood vessels near the surface. A congenital nevus, the mole a baby is born with, is another pigment-based mark; unlike a fading salmon patch, a mole doesn't disappear and instead gets monitored over the years for changes in size, color, or texture. And the small white bumps sometimes seen across a newborn's nose and cheeks — milia — are neither a vascular nor a pigment mark at all, just tiny pockets of trapped skin cells that clear on their own within a few weeks. Telling these apart mostly comes down to color, texture, and location, and a pediatrician can usually do it at a glance.

Does a salmon patch ever need treatment?

Most salmon patches need no treatment at all — no cream, no procedure, and no special skin care beyond what any baby's skin gets. Because the patch is flat and doesn't grow, there's nothing to remove or shrink in infancy, and the expected course is simply watching it fade on its own timeline. a flat mark that isn't growing is the reassuring sign; treatment decisions only come up for the minority of stork bites that stay prominent well past early childhood. Some of those families eventually ask a dermatologist about cosmetic laser treatment to lighten a persistent mark, similar to options used for other visible vascular marks — a personal, appearance-driven choice rather than a medical necessity, since a persistent stork bite carries no health risk on its own. The one thing worth flagging to a pediatrician is a mark that doesn't fit the usual pattern: raised instead of flat, growing instead of stable, or sitting somewhere other than the classic locations.

Common questions

Nothing except location — both are the same kind of mark, a salmon patch or nevus simplex. "Stork bite" refers to one at the nape of the neck, usually hidden under hair, while "angel kiss" refers to one on the eyelids, the bridge of the nose, or the center of the forehead. Some babies have both at once.

The underlying vessels don't return once a patch has genuinely faded, but a stork bite that never fully disappeared can look more prominent at times — flushed from crying, heat, sunburn, or exertion — well into adulthood. That's the same mark reddening temporarily, not a new one forming.

No differently than for the rest of an infant's skin. Standard guidance for babies under six months favors shade and protective clothing over sunscreen, and a salmon patch doesn't change that advice — it isn't more sun-sensitive than the skin around it.

On their own, no. A salmon patch in one of the typical locations is an extremely common, harmless finding unrelated to any underlying condition. It becomes worth a closer look only if it's unusually large, raised, growing, or paired with other unusual features — not because of the mark itself.

Pressure is the simplest test: a salmon patch blanches, meaning it lightens when pressed firmly, while a port-wine stain typically stays deep red or purple and doesn't fade as fully with pressure. A port-wine stain also doesn't fade over time the way most salmon patches do, so a persistently deep-colored patch is worth a pediatrician's look either way.

When a newborn mark isn't a simple birthmark

  • —A patch that is raised or firm rather than flat, or that appears to be growing
  • —A red or purple mark that does not lighten when pressed firmly
  • —A mark located somewhere other than the eyelids, forehead, nose, upper lip, or nape of the neck, especially if large or multiple
  • —Any mark accompanied by swelling, warmth, or pain

This article describes typical patterns for salmon patches and related newborn skin findings and is not a substitute for an in-person exam. A pediatrician or dermatologist can confirm what a specific mark is and whether anything further is needed.
