Broken Capillaries

Broken capillaries are the fine red or purple threads visible on the face, most often around the nostrils, cheeks and chin. The name is misleading: these vessels are not broken. They are facial telangiectasias, capillaries that have dilated permanently and stay filled with blood, which is exactly why they show through the skin.

A vessel that lost its spring

Facial capillaries constantly widen and narrow to manage temperature and emotion, the reflex behind blushing. That elasticity has limits: after intense, repeated dilation, the vessel wall loses its ability to contract back and stays open for good. Cumulative sun exposure adds to this by weakening the collagen that supports the vessel, so dilated capillaries multiply with age and sun.

What causes broken capillaries?

Broken capillaries come from a dilation reflex pushed past recovery, on facial skin where vessels sit close to the surface. Temperature extremes, sun, heat, alcohol and the inflammation of rosacea all overwork that reflex, while weakened collagen lets vessels dilate more easily. Knowing the triggers matters, because limiting them is what slows new vessels from forming.

1
An overworked dilation reflex

Facial capillaries dilate and contract many times a day to regulate temperature and respond to emotion. Each intense dilation stretches the wall a little. Repeated often enough, through cold-to-warm swings, hot showers or flushing, the wall eventually loses its spring and the capillary stays open. This is the core mechanism behind every visible facial vessel.

2
Temperature extremes and heat

Sudden shifts between cold outdoors and dry indoor heat, plus saunas, hot showers and intense exercise, all drive strong dilation. The Canadian winter is an ideal setting for this back-and-forth. Heat is one of the most reliable triggers, which is why managing temperature exposure is central to keeping new capillaries from forming.

3
Sun and weakened support

Cumulative sun exposure fragments the collagen that surrounds and supports capillary walls. Less supported, the vessels dilate more easily and sit closer to the surface. This is why dilated capillaries multiply with age and sun history, and why daily photoprotection is one of the most effective ways to slow their appearance.

4
Alcohol, friction and rosacea

Alcohol is a temporary vasodilator, friction and local trauma irritate surface vessels, and the chronic inflammation of rosacea keeps the dilation reflex active. None of these breaks a capillary, but each pushes the wall toward losing its spring. On reactive skin, they are common contributors to visible vessels over time.

How to Prevent
1

Daily photoprotection

Because sun weakens the collagen that supports vessel walls, daily broad-spectrum protection is the single most useful habit. It slows the fragmentation that lets capillaries dilate and surface, and it protects skin that is already reactive. This matters year-round, including bright winter days when snow reflects UV onto the face.

2

Limit heat extremes

Since heat strongly triggers dilation, reducing prolonged or sudden heat helps: cooler showers, care around saunas, and easing in and out of temperature extremes. This will not close existing vessels, but it removes a recurring signal that keeps the dilation reflex working and new capillaries forming.

3

Gentle, soothing skincare

Reactive skin does better with gentle, fragrance-conscious care than with harsh actives or aggressive exfoliation, which irritate vessels and feed redness. A calm, supportive routine protects the skin barrier and limits the inflammation that overworks the dilation reflex. Professional guidance helps match products to sensitive, vessel-prone skin.

4

Know the limits

Once a capillary stays dilated, it does not close on its own, so prevention limits new vessels rather than clearing existing ones. Because the dilation reflex and reactive terrain remain, addressing visible vessels means treating what is there while managing the triggers that would otherwise add more.

Vascular Lasers
The laser technologies used-such as YAG, Cutera, VBeam, Fotona or Perfecta-rely mostly on light as a concentrated energy source to treat various skin conditions. Each laser is characterized by a wavelength that extends from ultraviolet rays to infrared rays, with each wavelength targeting a precise condition.

Intense Pulsed Light Therapy (IPL)
Intense Pulsed Light (IPL) is a non-invasive technology that uses controlled pulses of light to target specific structures in the skin, including pigment (melanin), blood vessels, acne-causing bacteria and hair follicles. When absorbed, the light creates a controlled thermal effect that helps reduce discoloration, redness, inflammation or unwanted hair, while preserving the surrounding skin. Because this technology acts on pigment and blood vessels, it is not suitable for all skin types. Very dark skin tones, recently tanned skin or certain skin conditions may carry a higher risk of side effects, which is why a professional skin assessment is essential before treatment.

Advanced Fluorescence Technology (AFT)
AFT is an advanced light-based treatment that targets a range of common skin concerns—pigmentation, redness, acne, and early signs of aging—with no downtime. It’s a comfortable, non-invasive option for patients looking to visibly improve skin tone, texture, and clarity.
