Vascular lesions explained: red spots, spider veins & port-wine stains
“Vascular lesion” is a broad label, not one diagnosis. Cherry angiomas, facial telangiectasia, leg veins and congenital capillary malformations behave differently and need different plans.
Some vascular lesions are acquired benign growths, some are dilated vessels, and some are congenital malformations. Most are not dangerous. The diagnosis still matters before a laser or an injection is chosen, because the same red colour can mean very different things.
Several common conditions sit under the same umbrella
Cherry angiomas
Small red to purple papules made of proliferated blood vessels. Increasingly common with age, benign, and usually needing no treatment at all.
Telangiectasia
Fine visible vessels arising with sun damage, rosacea, genetics, steroid use or other causes.
Reticular and spider veins
Visible leg veins may be purely cosmetic, but symptoms or larger feeder veins can indicate underlying venous disease.
Capillary malformations
Port-wine stains are congenital malformations that can darken or thicken over decades rather than fading.
What tells them apart
| Lesion | Typical appearance | Usual approach |
|---|---|---|
| Cherry angioma | Small, dome-shaped, bright red, on trunk and limbs; increases in number with age | Reassurance; laser or electrosurgery if bothersome |
| Facial telangiectasia | Fine thread-like vessels, often on nose and cheeks | Treat the underlying driver, then vascular laser or light |
| Spider naevus | Central point with radiating vessels; blanches and refills from the centre | Usually benign; multiple new ones warrant medical assessment |
| Leg spider veins | Fine blue or red vessels, often thigh or calf | Assess for venous insufficiency first; sclerotherapy or laser |
| Port-wine stain | Flat pink to red patch present from birth, growing with the child | Pulsed-dye laser over multiple sessions; location determines further assessment |
| Infantile haemangioma | Appears in early weeks, grows, then involutes over years | Paediatric assessment; many need only monitoring |
Two features are worth knowing because they change the conversation: whether a lesion was present at birth, and whether it is changing. Those two questions separate most of the reassuring cases from the ones needing assessment.
Facial redness is not always “broken capillaries”
Visible facial vessels can accompany rosacea, chronic sun exposure, topical steroid use, or simply a naturally vascular skin type. Treating individual vessels without addressing rosacea or continued UV exposure produces incomplete or short-lived improvement — the vessels come back, and the patient concludes the laser did not work.
Laser and light devices target haemoglobin, but wavelength, pulse duration, vessel diameter, skin colour and cooling all affect both safety and response. Device settings appropriate for one skin type can cause pigmentary change in another, which is why assessment matters more than the brand of machine.
Where rosacea is present, controlling it first makes vascular treatment more effective and longer-lasting. Doing the reverse means paying for maintenance sessions indefinitely.

Leg veins deserve a different assessment
Spider veins are fine superficial vessels; reticular veins are larger and sit deeper. Where there is aching, heaviness, swelling, skin change, prominent varicose veins or recurrent symptoms, underlying venous insufficiency should be considered rather than treating only the visible surface vessels.
This matters practically. Treating surface veins while a refluxing feeder vein continues to fill them tends to produce disappointing and short-lived results, which is why assessment sometimes includes imaging of the deeper venous system before any cosmetic treatment.
Sclerotherapy is commonly used for selected leg veins, while laser suits smaller vessels or particular sites. Vessel size and depth determine the choice more than preference does.
Port-wine stains are congenital capillary malformations
They are present from birth, grow proportionally with the child, and may become darker, thicker or develop nodules over decades. Unlike infantile haemangiomas, they do not resolve on their own. Pulsed-dye laser is the well-established approach, usually requiring multiple sessions, with earlier treatment generally producing better response.
A capillary malformation involving certain areas of the forehead, upper eyelid or scalp may warrant specialist assessment for associated eye or neurological conditions, rather than being treated as a purely cosmetic birthmark. This is a paediatric assessment question and should not be deferred to a cosmetic consultation.
Birthmarks in babies: two different things
Parents frequently arrive having read about both and unsure which applies. The distinction is straightforward and clinically important.
- Infantile haemangiomas typically appear in the first weeks of life, grow for several months, then slowly involute over years. Many need only monitoring, though those near the eye, airway, nose, lip or nappy area, and large or ulcerating ones, need earlier paediatric assessment.
- Port-wine stains are present at birth, do not involute, and grow with the child.
Either way, a vascular birthmark in an infant is a paediatric question first. Cosmetic treatment planning follows assessment rather than replacing it.
When a “red spot” should be examined first
- Rapid change in size, colour or shape.
- Repeated unexplained bleeding or ulceration.
- Pain, significant swelling or a pulsatile lesion.
- A new vascular-appearing lesion that does not fit the usual pattern, particularly one that keeps bleeding.
- Several new spider naevi appearing together in an adult.
- A birthmark in a child with a concerning location or associated symptoms.
- Leg veins with persistent swelling, skin breakdown, or a painful swollen calf suggesting possible thrombosis, which needs urgent assessment.
Some pigmented and non-vascular lesions can appear red or pink, including certain skin cancers. A lesion that bleeds repeatedly, will not heal, or looks different from anything else on the skin should be examined before any cosmetic device is used on it.
Treatment depends on vessel type, depth and location
Vascular laser
Targets haemoglobin selectively; used for facial vessels, cherry angiomas and selected vascular birthmarks.
Intense pulsed light
Broad-spectrum light can help diffuse facial redness and sun-related vascular change in suitable skin types.
Sclerotherapy
A sclerosant is injected into selected leg veins so the vessel closes and is gradually resorbed.
Electrosurgery
Useful for small individual lesions such as some cherry angiomas, particularly where a laser is not appropriate.
Recurrence and new vessels are common, because treatment removes visible vessels without removing the genetic, hormonal, sun-related or venous factors that produced them. That is not treatment failure; it is worth understanding before starting, so the ongoing cost is expected rather than resented.
What treatment is actually like
Vascular treatments are usually quick but not entirely comfortable, often described as a snapping or hot sensation. Expect redness immediately afterwards, and bruising or temporary darkening of treated vessels in many cases — particularly with stronger settings, which is worth planning around socially.
Several sessions are usual rather than exceptional. Larger or deeper vessels respond less predictably than fine superficial ones, and results build across a course.
Aftercare is straightforward and matters: sun protection, avoiding heat and vigorous exercise immediately afterwards, and reporting blistering, prolonged pain or any sign of infection rather than waiting. Tell the clinician beforehand about photosensitising medication, recent sun exposure or tanning, a history of cold sores if treating around the mouth, pregnancy, and any tendency to pigment after inflammation.
Questions patients ask
Are cherry angiomas dangerous?
They are benign and become more common with age. Treatment is optional and cosmetic, though a lesion that changes or bleeds repeatedly should be examined.
Why do I keep getting new red spots?
Cherry angiomas increase in number with age, and facial vessels recur where sun exposure, rosacea or genetics continue to drive them. Treatment removes vessels, not causes.
Can broken capillaries on my face be cured permanently?
Individual vessels can be cleared, but new ones form if the underlying driver persists. Controlling rosacea and sun exposure makes results last considerably longer.
How many sessions will I need?
Usually several. Fine superficial vessels respond most predictably; larger or deeper vessels are less certain and results build across a course.
Does vascular laser hurt?
It is usually brief but not entirely comfortable, often described as a snapping or hot sensation. Redness afterwards is expected and bruising is common.
Is laser safe for darker skin?
It can be, with appropriate device choice and settings, but the risk of pigmentary change is higher. This is a reason for assessment rather than choosing by machine brand.
Laser or sclerotherapy for leg veins?
It depends on vessel size and depth. Sclerotherapy suits many leg veins, while laser is useful for smaller vessels and particular sites.
Why did my leg veins come back?
Often because a deeper refluxing vein continues to fill them. Where symptoms or varicose veins are present, underlying venous insufficiency should be assessed.
Will a port-wine stain fade on its own?
No. Unlike infantile haemangiomas, capillary malformations do not involute and may darken or thicken over time.
My baby has a red birthmark — what should I do?
Have it assessed. Infantile haemangiomas and port-wine stains behave differently, and location near the eye, airway, nose or lip needs earlier paediatric review.
Should I worry about several new spider naevi?
A single one is usually benign, but several appearing together in an adult warrants medical assessment rather than cosmetic treatment.
What should I tell the clinician before treatment?
Photosensitising medication, recent sun exposure or tanning, cold sore history if treating around the mouth, pregnancy, and any tendency to pigment after inflammation.
