Broken Capillaries and Telangiectasia
Broken Capillaries and Telangiectasia — small, dilated blood vessels visible just beneath the skin's surface, often appearing as fine red, purple, or bluish lines on the cheeks, nose, or around the nostrils. Despite the common name, the vessels are not truly broken but rather widened and persistently visible. They are a frequent cosmetic concern and can be linked to sun damage, genetics, or conditions like rosacea.
Key points
- Telangiectasia refers to permanently dilated superficial blood vessels, which the term broken capillaries popularly describes.
- Contributing factors include chronic sun exposure, aging, genetics, rosacea, and repeated flushing or trauma to the skin.
- They are typically a cosmetic rather than medical concern, though they can accompany underlying conditions worth evaluating.
- Sun protection and gentle skincare may help limit worsening, while in-office treatments like laser or light therapy are commonly used to reduce their appearance.
Red marks that are not telangiectasia
| Often confused with | How to tell them apart |
|---|---|
| A transient flush | Diffuse warmth that rises and fades within the hour; a telangiectasia is a fixed line that stays. |
| Post-inflammatory erythema | A flat pink patch left where a spot healed, fading over months, with no threadlike vessel in it. |
| Cherry angioma | A small domed red dot standing proud of the skin, commoner on the trunk than the face. |
| Spider naevus | One central point with fine legs radiating out; press the centre and the whole lesion blanches. |
| Bruising or petechiae | Blotchy purple that does not blanch under pressure and shifts through green and yellow as it clears. |
Why the vessels stay open
The popular name is misleading, and correcting it is the most useful line on this page: these vessels are not broken. Nothing has ruptured and nothing is leaking. They are small superficial vessels that have widened and lost the recoil needed to narrow again, so they stay open and read as fine red or bluish threads.
Distribution follows the anatomy. Skin over the nose, nostril rims and cheekbones is thin, sits above a dense superficial vascular network and takes the most sun and wind. Cumulative ultraviolet exposure degrades the collagen bracing vessel walls, while years of flushing, rosacea, pregnancy, prolonged topical corticosteroid use on the face and physical trauma each push the same way.
Clearing the vessel versus calming the background
An established telangiectasia is not closed by any topical product. Serums described as strengthening capillaries do not reach or remodel a dilated vessel, and such claims deserve scepticism. What topicals do achieve is real but different: azelaic acid and niacinamide reduce the diffuse background redness around the vessels, which makes them less conspicuous.
Clearing the vessel itself means targeting it with light. Vascular laser and intense pulsed light, delivered by a trained clinician after assessment, heat the blood inside the vessel so its wall collapses and is absorbed. Several sessions are usual, and results vary with skin tone and vessel size. Daily broad-spectrum sunscreen and limiting known flushing triggers slow new ones forming.
Signs worth a doctor's opinion rather than a laser
Most facial telangiectasia is cosmetic. Some patterns are not. Several new spider naevi appearing together, particularly across the upper body, warrant medical assessment, since they can accompany liver or hormonal changes; a single one, common in pregnancy and childhood, usually does not.
Arrange an appointment for telangiectasia on the lips, tongue or fingertips alongside recurrent nosebleeds, for a vessel that bleeds, enlarges quickly or changes colour, and for visible vessels in a child. If they followed a corticosteroid cream used on the face, raise it with the prescriber rather than stopping it yourself.
Frequently asked
Are broken capillaries actually broken?
Not usually; the vessels are dilated and more visible rather than ruptured, which is why the clinical term telangiectasia is more accurate.
Can skincare remove visible capillaries?
Topical products may help calm surrounding redness and protect the skin, but visibly dilated vessels typically respond best to professional treatments such as laser therapy.
Can scrubbing or hot water make them worse?
Heat, steam and vigorous rubbing provoke flushing, and repeated flushing is one contributor. Neither conjures a vessel overnight, but lukewarm water and a gentle touch are the sensible default.
Do visible vessels ever fade on their own?
Those following pregnancy or a one-off injury sometimes settle within months. Vessels built up over years of sun exposure generally persist, which is why treatment gets discussed at all.
Why did they appear during pregnancy?
Higher oestrogen and increased blood volume widen small vessels, so new ones often surface later in pregnancy. Many fade in the months after birth; those still present at a year rarely resolve unaided.
How many laser sessions are usually needed?
A clinician estimates this after seeing the vessels, and the honest answer is that it varies. Fine cheek vessels often need fewer sessions than larger ones on the nose, and maintenance is common.
