Understanding Vascular Lesion Treatments

Last updated: 11 February 2026

Vascular lesions — visible blood vessels, red spots, and redness on the skin — are among the most common dermatological concerns seen in aesthetic clinics across the United Kingdom. From delicate thread veins on the cheeks to port wine stains present from birth, these conditions affect millions of people and can have a significant impact on self-confidence. Fortunately, modern treatment technologies offer highly effective solutions for the vast majority of vascular lesions. This guide provides a comprehensive overview of vascular lesion types, treatment options, and what patients can expect.

What Are Vascular Lesions?

Vascular lesions are abnormalities of the blood vessels that are visible through the skin. They range from tiny spider veins (telangiectasia) measuring less than 1mm in diameter to large, complex birthmarks covering significant areas of the face or body. Vascular lesions are broadly categorised into two groups: vascular malformations (present from birth, caused by structural abnormalities in vessel development) and acquired vascular lesions (developing during life due to sun damage, ageing, hormonal changes, or other factors).

Common Types of Vascular Lesions

Spider veins (telangiectasia) are dilated superficial blood vessels, typically 0.1-1mm in diameter, appearing as fine red or purple lines. They most commonly affect the face (particularly the nose and cheeks) and legs. Facial spider veins are often associated with rosacea, sun damage, or genetic predisposition.

Cherry angiomas (Campbell de Morgan spots) are small, bright red dome-shaped papules caused by proliferation of capillaries. They are extremely common, affecting over 75% of adults over 75, and are entirely benign. Spider naevi consist of a central arteriole with radiating smaller vessels, resembling a spider’s web. Port wine stains (naevus flammeus) are flat, pink-to-purple birthmarks caused by capillary malformation. They are present from birth and tend to darken and thicken over time without treatment. Haemangiomas are raised, red vascular tumours most common in infants, often resolving spontaneously but sometimes requiring treatment.

Lesion Type	Appearance	Location	Cause	Best Treatment
Telangiectasia (spider veins)	Fine red/purple lines	Face, legs	Sun, ageing, rosacea	IPL, Nd:YAG laser
Cherry angioma	Small red dome	Trunk, limbs	Ageing	Electrocautery, laser
Spider naevus	Central dot + radiating vessels	Face, upper body	Hormonal, liver disease	Electrocautery, laser
Port wine stain	Flat pink/purple patch	Face, body	Congenital malformation	Pulsed dye laser
Rosacea redness	Diffuse facial redness	Central face	Inflammatory condition	IPL, V-beam laser
Broken capillaries	Visible small vessels	Nose, cheeks	Trauma, sun, alcohol	IPL, diathermy

Treatment Technologies

Intense Pulsed Light (IPL)

IPL devices emit broad-spectrum light (typically 500-1200nm) that is selectively absorbed by oxyhaemoglobin in the blood vessels. This thermal energy causes photocoagulation — the blood within the vessel heats and coagulates, causing the vessel wall to collapse. The body then gradually reabsorbs the treated vessel over the following weeks. IPL is particularly effective for diffuse facial redness, fine telangiectasia, and rosacea-related vascular changes.

A typical course involves 3-6 sessions spaced 3-4 weeks apart. Each session takes approximately 20-30 minutes for a full face. Patients experience a sensation similar to a rubber band snap during treatment, with mild redness and slight swelling lasting 24-48 hours afterwards.

Pulsed Dye Laser (PDL)

The pulsed dye laser (commonly known as V-beam) emits light at 585-595nm — the precise absorption peak of oxyhaemoglobin. This makes it the most targeted vascular laser available, with excellent specificity for blood vessels and minimal damage to surrounding tissue. PDL is the gold-standard treatment for port wine stains, having been used for this indication since the 1980s with extensive clinical evidence.

The PDL can be set to purpuric or sub-purpuric settings. Purpuric settings produce temporary bruising (lasting 7-14 days) but achieve greater vessel clearance per session. Sub-purpuric settings avoid bruising but may require more treatment sessions. The choice depends on the lesion type, patient preferences, and social downtime considerations.

Nd:YAG Laser (1064nm)

The Nd:YAG laser at 1064nm wavelength penetrates deeper into the skin than the PDL, making it effective for larger, deeper vessels that IPL and PDL cannot adequately treat. It is particularly useful for leg veins (1-3mm diameter), deeper facial veins, and periorbital veins. The longer wavelength also makes it safer for treating vascular lesions in patients with darker skin tones (Fitzpatrick IV-VI).

Electrocautery and Diathermy

These techniques use electrical energy to generate heat at the tip of a fine needle, which is applied directly to the vessel. The heat causes the vessel wall to seal and collapse. Electrocautery is particularly effective for isolated spider veins, cherry angiomas, and spider naevi. It offers immediate visible results in many cases, with treated vessels disappearing during the treatment. The procedure uses local anaesthetic and takes 15-30 minutes depending on the number of lesions.

Sclerotherapy

Whilst primarily used for leg veins, sclerotherapy involves injecting a sclerosant solution (such as polidocanol or sodium tetradecyl sulphate) directly into the affected vessel. The solution damages the vessel lining, causing it to close and eventually be reabsorbed. Sclerotherapy is the gold-standard treatment for reticular veins (1-3mm) and small varicose veins on the legs. It is less commonly used for facial veins due to the higher risk of complications in the facial vasculature.

Treatment Selection: Matching Technology to Lesion

The choice of treatment technology depends on several factors including the type and size of the vascular lesion, its depth within the skin, the patient’s skin type (Fitzpatrick classification), the location on the body, and the patient’s tolerance for downtime. A qualified practitioner will assess all these factors during the consultation to recommend the most appropriate treatment approach.

What to Expect During Treatment

Before Treatment

Patients should avoid sun exposure for 2-4 weeks before vascular laser or IPL treatment, as tanned skin increases the risk of complications. Blood-thinning medications and supplements (aspirin, ibuprofen, fish oil, vitamin E) should be discontinued 7-10 days prior with medical approval. Topical retinoids should be stopped 5-7 days before treatment.

During Treatment

Most vascular treatments are well-tolerated with topical anaesthetic cream or cooling devices. IPL and laser treatments produce a sensation of heat and mild snapping. Electrocautery produces a brief stinging sensation at each point of treatment. Sessions typically last 15-45 minutes depending on the area and number of lesions being treated.

After Treatment

Immediately after treatment, the skin may appear red, slightly swollen, and warm — similar to mild sunburn. With PDL on purpuric settings, bruising is expected and can be quite vivid for 7-14 days. Treated vessels may initially appear darker or more prominent before fading over the following 2-6 weeks. Sun protection with SPF 50 is essential during the healing period to prevent post-inflammatory hyperpigmentation.

Results and Expectations

The number of treatments required varies by lesion type. Small spider veins and cherry angiomas may clear in a single session. Diffuse rosacea redness typically requires 3-6 IPL sessions. Port wine stains often require 6-12+ PDL sessions, with darker, thicker stains requiring more treatments. Leg veins may need 2-4 sessions of laser or sclerotherapy.

Complete clearance is achievable for many types of vascular lesion, though some conditions — particularly rosacea and port wine stains — may require ongoing maintenance treatments as new vessels can develop over time.

Costs in the UK

IPL treatment for facial redness costs approximately £150-£350 per session. Pulsed dye laser ranges from £200-£500 per session depending on the area treated. Nd:YAG laser for leg veins costs £200-£400 per session. Electrocautery for individual lesions is typically £100-£250 per session. Sclerotherapy ranges from £250-£500 per session.

Port wine stain treatment may be available on the NHS, particularly for children and for lesions on the face. Referral is through a consultant dermatologist or plastic surgeon. NHS treatment typically uses the pulsed dye laser and may involve waiting lists.

Safety and Regulation

Vascular laser and IPL treatments should be performed by trained practitioners operating within an appropriate clinical setting. In England, clinics performing laser treatments should be registered with the Care Quality Commission (CQC). The practitioner should hold relevant qualifications and be listed on a recognised register. A thorough consultation including skin type assessment, medical history review, and test patch is essential before commencing treatment.
