Baby skin is sensitive and changes frequently. If you are noticing has a port-wine stain, here is what you need to know.
The short answer
A port-wine stain is a flat, pink, red, or purple birthmark caused by abnormal blood vessels in the skin. It is present at birth, permanent, and does not fade over time like some other birthmarks. While most are purely cosmetic, those on the face may require medical evaluation and early laser treatment for best results.
Key takeaways
- A port-wine stain is a flat, pink, red, or purple birthmark caused by abnormal blood vessels in the skin. It is present at birth, permanent, and does not fade over time like some other birthmarks. While most are purely cosmetic, those on the face may require medical evaluation and early laser treatment for best results.
- Usually normal when: A flat, pink, red, or purple patch present at birth that does not blanch (turn white) when pressed
- Call your doctor if: Your baby with a facial port-wine stain develops seizures, developmental delays, or vision problems
- Varies by age — see the age-by-age breakdown below
“Eczema is very common in babies and children. About 1 in 10 children will develop eczema, typically starting in the first few months of life.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, AAD, NIH guidelines, a port-wine stain is a flat, pink, red, or purple birthmark caused by abnormal blood vessels in the skin. It is present at birth, permanent, and does not fade over time like some other birthmarks. While most are purely cosmetic, those on the face may require medical evaluation and early laser treatment for best results. At 0-3 months, port-wine stains are present at birth and appear as flat, pink or light red patches, most commonly on the face, neck, or limbs. Unlike salmon patches (stork bites), port-wine stains do not fade. Early evaluation by a pediatric dermatologist is important, especially for facial birthmarks, as early laser treatment leads to better outcomes. It is generally considered normal when a flat, pink, red, or purple patch present at birth that does not blanch (turn white) when pressed. However, you should contact your pediatrician promptly if your baby with a facial port-wine stain develops seizures, developmental delays, or vision problems.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Port-wine stains are present at birth and appear as flat, pink or light red patches, most commonly on the face, neck, or limbs. Unlike salmon patches (stork bites), port-wine stains do not fade. Early evaluation by a pediatric dermatologist is important, especially for facial birthmarks, as early laser treatment leads to better outcomes.
3-12 months
During this period, the port-wine stain may darken from pink to a deeper red or purple as your baby's circulation matures. If the birthmark involves the forehead and upper eyelid, your pediatrician will monitor for Sturge-Weber syndrome, a rare condition requiring eye and neurological assessment. Most port-wine stains are isolated findings with no associated issues.
12 months - 3 years
Port-wine stains continue to darken over time and do not disappear. The affected skin may begin to thicken slightly or develop small bumps. Laser treatment, typically started in infancy, can lighten the birthmark significantly. Multiple treatment sessions spaced several months apart are usually needed for optimal results.
3+ years
Without treatment, port-wine stains become darker and the skin may thicken further. Some develop a bumpy, cobblestone texture. Laser therapy remains effective at this age but may require more sessions than early treatment. Makeup can also help camouflage the birthmark if desired. Ongoing dermatology follow-up is important.
What to Tell Your Pediatrician
- Describe when you first noticed has a port-wine stain and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if the port-wine stain involves the forehead, upper eyelid, or area around the eye.
- Mention if you are interested in early laser treatment for cosmetic reasons.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- A flat, pink, red, or purple patch present at birth that does not blanch (turn white) when pressed
- The birthmark is located on the face, neck, arms, or legs and does not involve the eye or forehead
- Your baby is otherwise healthy with normal vision, development, and no seizures or neurological concerns
- The birthmark is not painful, does not bleed, and does not seem to bother your baby
- The port-wine stain involves the forehead, upper eyelid, or area around the eye
- You are interested in early laser treatment for cosmetic reasons
- The birthmark is thickening, developing bumps, or bleeding easily
- You have concerns about associated conditions like Sturge-Weber syndrome
- Your baby with a facial port-wine stain develops seizures, developmental delays, or vision problems
- The birthmark becomes infected with swelling, warmth, drainage, or fever
What You Can Do at Home
- Keep track of when you notice has a port-wine stain — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that a flat, pink, red, or purple patch present at birth that does not blanch (turn white) when pressed — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
- While monitoring at home, seek immediate care if your baby with a facial port-wine stain develops seizures, developmental delays, or vision problems.

Related Skin Concerns
My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
Baby Acne (Neonatal Acne)
Baby acne is a very common, harmless condition that appears as small red or white bumps on your newborn's face, usually around 2-4 weeks of age. It is caused by maternal hormones still circulating in your baby's system and clears up on its own within a few weeks to months without any treatment.
Baby Acne vs Eczema: How to Tell the Difference
Baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management.
Alopecia Areata in Babies
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing round, smooth patches of hair loss. While uncommon in babies, it can occur at any age. The condition is not painful or contagious. Many children experience spontaneous hair regrowth, though it may take months. Your pediatrician or dermatologist can confirm the diagnosis.
