You noticed it in the mirror. A small red mark with tiny blood vessels radiating outward from a central dot, like a miniature spider sitting on your skin. It does not hurt. It has not changed in weeks. It is just there, slightly visible, and you are not sure what it is or whether to do anything about it.
Most likely, this is a spider angioma. It is one of the most common benign vascular marks on the skin, it is not dangerous in most people, and if you want it gone, there are real options. This guide covers what it is, whether to be concerned, how it differs from similar-looking marks, and the best ways to remove it.
Key takeaways
Spider angiomas are benign vascular marks. Identify first, then decide what to do.
- A spider angioma is a central red dot with radiating vessels forming a spider-web pattern on the skin surface.
- Press on the central dot: a spider angioma blanches (turns white) completely and refills from the center out. If it does not blanch, see a doctor.
- Spider angiomas are benign in most people and do not become cancerous.
- Multiple spider angiomas appearing suddenly in an adult can be worth discussing with a doctor, particularly with a history of heavy alcohol use or liver concerns.
- Confirmed cosmetic spider angiomas can be treated at home with a plasma pen. The skin is typically clear by weeks two to three.
What is a spider angioma?
A spider angioma (also called a spider nevus or vascular spider) is a small cluster of widened blood vessels just beneath the skin surface. A central red dot, which is a dilated arteriole, feeds a pattern of smaller vessels that radiate outward in all directions. The result looks like a spider with its legs spread, which is exactly where the name comes from.
According to the American Academy of Dermatology, spider angiomas are among the most common benign vascular lesions in adults. They are listed in clinical references on NIH MedlinePlus as a benign skin condition associated with dilated blood vessels near the skin surface.
What a spider angioma looks like
The central dot is typically 1 to 3 millimeters across, bright red, and slightly raised. The radiating vessels extend 5 to 10 millimeters outward. If you press on the central dot with a fingertip and release, the whole mark briefly blanches (turns white) and then refills from the center out. That blanching pattern is the classic diagnostic feature of a spider angioma and what distinguishes it from a flat red birthmark or a bruise.
The mark is painless, not itchy, and does not change from day to day. In good lighting it is noticeably red; in dimmer light it may look faint. It does not crust, bleed, or become inflamed on its own.
Where spider angiomas appear on the body
Spider angiomas most often appear on the face: the cheeks, the nose, and around the eyes. They also appear on the neck, upper chest, and upper arms. In the general population they tend to cluster above the waist. In children, the face and hands are the most common locations. They are more common in people with fair skin and in those with higher circulating estrogen levels, whether from pregnancy, oral contraceptives, or other sources.
Is a spider angioma dangerous?
For most adults and children, no. Spider angiomas are benign. They are not cancer, they are not pre-cancer, and a single spider angioma on the face in a healthy adult is almost always a cosmetic finding with no medical significance.
When spider angiomas are just cosmetic
A single spider angioma, or a small number of them, in an otherwise healthy adult with no other symptoms is a cosmetic issue. It will not spread the way an infection does, it will not become cancerous, and it is not a sign that anything is wrong internally. Many people develop one or two after sun exposure, after a period of hormonal change, or for no obvious reason at all.
When to see a doctor about a spider angioma
Two situations warrant a medical conversation. First: if you develop many spider angiomas at once, particularly if you drink alcohol regularly, that pattern can be a skin sign of liver disease. The liver processes estrogen, and when liver function is impaired, estrogen is not cleared efficiently and blood estrogen levels rise. Mayo Clinic notes that multiple spider angiomas in adults with known liver disease or heavy alcohol use are a recognized finding worth evaluating.
Second: if you are pregnant and develop spider angiomas, that is normal and expected (more on this below), but if the marks are extensive or unusual in appearance, loop in your OB or midwife.
See a doctor if
- You develop many spider angiomas suddenly, especially with a history of alcohol use or liver disease.
- You are pregnant and the marks are unusually extensive or accompanied by other symptoms.
- The mark does not blanch when pressed (a non-blanching red mark may not be a spider angioma).
- The mark is growing, becoming painful, or looks different from a typical spider pattern.
- You are uncertain whether what you have is a spider angioma and want confirmation before treating it.
Spider angioma vs cherry angioma and other look-alikes
Several common red skin marks are mistaken for spider angiomas. The table below shows the four most common side by side.
Spider angioma vs cherry angioma
Cherry angiomas are round, dome-shaped, uniformly red marks. They have no radiating vessels and no central feeding dot in the spider pattern sense. Cherry angiomas tend to appear on the chest, abdomen, and back rather than the face, and they are solid-colored rather than patterned. For a full side-by-side, see our guide to cherry angioma vs spider angioma.
Spider angioma vs broken capillaries
Broken capillaries on the face are fine red or purple lines, often on the cheeks and nose, with no central dot or spider-web structure. They form in linear or branching patterns and have no single feeding arteriole. If you see branching red lines without a central red dot, you are more likely looking at broken capillaries than a spider angioma. For at-home options for broken capillaries specifically, see our guide on broken capillary removal at home.
Spider angioma vs petechiae
Petechiae are small flat red or purple dots caused by minor bleeding under the skin. They do not blanch when pressed. If you press on a red mark and it does not turn white, it is not a spider angioma and you should have it evaluated by a doctor. Petechiae can be caused by a range of things, some minor and some requiring medical attention.
What causes spider angiomas?
Spider angiomas form when a small arteriole near the skin surface dilates and the vessels feeding off it enlarge to match. What causes that dilation varies by situation.
Spider angiomas in pregnancy
Pregnancy is one of the most common causes of spider angiomas. Estrogen levels rise sharply during pregnancy and cause blood vessels to dilate. The face, neck, and upper chest are common locations. Spider angiomas that appear during pregnancy typically resolve on their own within a few months after delivery, once estrogen returns to normal. They are a benign, expected finding that requires no treatment in most cases. For more detail on the hormonal mechanisms, see our guide on spider angioma causes, pregnancy, and liver.
The estrogen and liver connection
The liver breaks down estrogen. When liver function is reduced, whether due to liver disease, alcohol use, or other factors, estrogen is not cleared efficiently and blood estrogen levels rise. The resulting vascular dilation can produce spider angiomas in larger numbers than would appear in a healthy adult. This is why multiple spider angiomas in an adult without a clear hormonal explanation can sometimes be a signal worth investigating with a doctor. It does not mean something is seriously wrong, but it is worth naming the connection.
Sun damage and other contributing factors
Sun damage is a contributing factor in some spider angiomas, particularly those on the face and nose in people with fair skin and a long history of outdoor sun exposure. Repeated UV damage to the small blood vessels near the skin surface causes them to dilate over time. Oral contraceptives and hormone replacement therapy, which raise estrogen levels, are also associated with higher rates of spider angiomas in otherwise healthy adults.
How to remove a spider angioma at home
Spider angiomas do not go away on their own in adults (unlike in pregnancy, where hormonal resolution is possible). If you have confirmed that the mark is a spider angioma and want it removed, there are real options.
How the plasma pen works on spider angiomas
The OcuraLife Plasma Pen targets the central arteriole of a spider angioma with focused plasma energy. The heat collapses the feeding vessel, which causes the whole radial pattern to fade. Most spider angiomas take approximately five minutes per spot. The pen has nine power settings, so you can start at a lower intensity and adjust based on your skin's response.
This approach targets the same vessel structure as professional laser and IPL treatments, at a fraction of the cost and without a clinic appointment. The pen is not a medical device and does not replace dermatological diagnosis: it is an at-home cosmetic tool for confirmed, benign marks in safe locations away from the eyes.
What to expect after treatment
Treatment day: The treated spot will look slightly red or pink immediately after. A small protective scab forms over the treated area within the first day.
Days 3 to 7: The scab dries and separates on its own. Do not pick it. The skin underneath is healing during this period.
Weeks 2 to 3: The treated area reveals clear skin. The spider angioma pattern has faded or is gone entirely for most people after a single treatment.
At-home treatment vs professional options
Professional options for spider angiomas include laser therapy, intense pulsed light (IPL), and electrocautery. These are effective but typically cost between $200 and $600 per session at a clinic. For a single confirmed cosmetic mark in a healthy adult, at-home plasma pen treatment is a practical first step. For multiple angiomas, marks near the eyes, or any mark you are unsure about, start with a dermatologist visit.
