Understanding Vascular Lesions: Treatment Approaches

Vascular lesions encompass a broad spectrum of conditions characterised by abnormal blood vessels visible on or beneath the skin surface. From spider veins and broken capillaries to port wine stains and cherry angiomas, these common presentations affect millions of individuals and can cause significant cosmetic concern. Modern aesthetic medicine offers highly effective, evidence-based treatments for the vast majority of vascular lesions.

Types of Vascular Lesions

Telangiectasia (Spider Veins)

These fine, dilated blood vessels measuring 0.5-1mm in diameter commonly appear on the face (particularly the nose, cheeks, and chin) and legs. They result from chronic UV exposure, rosacea, hormonal changes, or genetic predisposition. Research in the British Journal of Dermatology indicates that facial telangiectasia affects up to 15% of the adult population.

Cherry Angiomas (Campbell de Morgan Spots)

Bright red to purple dome-shaped papules caused by proliferating capillaries. They increase in frequency with age, affecting over 75% of adults over 75. While completely benign, they are a frequent cosmetic concern.

Spider Naevi

Central arterioles with radiating capillary branches creating a spider-like pattern. Common in children and pregnant women due to hormonal influence. Multiple spider naevi in adults may warrant investigation for liver disease.

Port Wine Stains

Congenital vascular malformations caused by an absence of normal nerve supply to blood vessel walls, resulting in persistent vasodilation. They appear as flat, pink to deep purple patches that darken and thicken with age if untreated.

Rosacea-Related Vascular Changes

Persistent erythema, flushing, and telangiectasia associated with rosacea represent some of the most common vascular presentations seen in aesthetic practice. The vascular component of rosacea is driven by dysregulated neurovascular signalling and chronic inflammation.

Treatment Options

Vascular Lasers

Laser treatment is the gold standard for most vascular lesions. Lasers work by selectively targeting haemoglobin (the red pigment in blood), causing thermal destruction of the abnormal vessel while sparing surrounding tissue — a principle known as selective photothermolysis.

Pulsed Dye Laser (PDL – 595nm): The gold standard for vascular lesions, PDL delivers short pulses of yellow light preferentially absorbed by oxyhaemoglobin. It is highly effective for telangiectasia, port wine stains, rosacea-related redness, spider naevi, and some scars. Side effects are typically limited to temporary purpura (bruising) lasting 7-14 days.

Nd:YAG Laser (1064nm): This longer wavelength penetrates deeper into tissue, making it effective for deeper and larger vessels, leg veins (1-4mm), blue/purple vascular lesions, and darker skin types where PDL carries higher pigmentation risk.

KTP Laser (532nm): Effective for superficial red vascular lesions, particularly fine telangiectasia and cherry angiomas. Its shorter wavelength limits penetration depth but provides precise superficial treatment.

Intense Pulsed Light (IPL)

IPL delivers broad-spectrum light filtered to target haemoglobin. While less specific than laser, IPL is effective for diffuse redness, background erythema, and mild telangiectasia. It is often used in combination with laser treatment for comprehensive vascular rejuvenation.

Sclerotherapy

For leg veins, injection of a sclerosing agent (typically sodium tetradecyl sulphate or polidocanol) directly into the vessel causes endothelial damage and eventual vessel closure. Evidence in the Cochrane Database of Systematic Reviews confirms sclerotherapy as an effective treatment for varicose and spider veins.

Electrocautery

Fine-needle electrocautery uses electrical current to cauterise individual vessels. This is particularly effective for isolated telangiectasia and cherry angiomas, offering immediate results with minimal cost.

Treatment Considerations by Skin Type

Vascular laser treatment in darker skin types (Fitzpatrick IV-VI) requires careful consideration due to competing absorption by melanin. Longer wavelength lasers (Nd:YAG 1064nm) are preferred, as they minimise melanin absorption. Longer pulse durations and lower fluences are used, and epidermal cooling is essential to protect the melanin-containing epidermis.

What to Expect During Treatment

Most vascular laser treatments cause a snapping sensation similar to an elastic band. Cooling devices integrated into the laser handpiece minimise discomfort. Sessions typically last 15-30 minutes depending on the area treated. Immediately after treatment, treated vessels may appear darker or bruised — this is expected and resolves within 1-2 weeks.

Post-Treatment Care

Following vascular treatment, patients should apply cold compresses to reduce swelling, avoid sun exposure and apply SPF 50 daily, avoid hot baths, saunas, and strenuous exercise for 48 hours, not take aspirin or blood-thinning medications unless medically prescribed, and wear compression stockings if leg veins were treated.

When to Seek Medical Assessment

While most vascular lesions are benign cosmetic concerns, certain presentations warrant medical investigation. These include rapidly growing vascular lesions, new vascular lesions associated with other symptoms, multiple spider naevi in adults, vascular lesions that bleed spontaneously, and asymmetric or unusual-appearing lesions.

Frequently Asked Questions

How many laser sessions are needed for vascular lesions?

Simple telangiectasia and cherry angiomas often respond in 1-2 sessions. Rosacea-related redness typically requires 3-5 sessions. Port wine stains may need 6-10 or more sessions depending on depth and colour.

Can vascular lesions come back after treatment?

Treated vessels are permanently destroyed. However, new vessels can develop over time due to ongoing UV exposure, hormonal changes, or the underlying condition (such as rosacea). Maintenance treatments every 12-24 months can manage recurrence.

Is vascular laser treatment safe during pregnancy?

Elective laser treatments are generally avoided during pregnancy and breastfeeding as a precautionary measure. Pregnancy-related spider naevi often resolve spontaneously within 3-6 months postpartum.

What is the difference between a vascular lesion and a mole?

Vascular lesions are caused by blood vessel abnormalities and typically appear red, pink, or purple. Moles are melanocytic lesions that appear brown or black. Any lesion that changes in size, shape, or colour should be assessed by a dermatologist.
