Vascular Lesions

Visible blood vessel abnormalities that appear at or near the skin surface, ranging from fine thread veins and broken capillaries to more prominent birthmarks and port wine stains. Most are benign and can be significantly improved with laser or light-based treatments.

What Are Vascular Lesions?

Vascular lesions is a broad clinical term for any visible abnormality involving blood vessels at or near the skin surface. In aesthetic practice, the most commonly treated vascular lesions are those that are cosmetically visible and benign, meaning they carry no medical risk but affect the appearance of the skin. These include thread veins and spider veins, which are small permanently dilated superficial blood vessels; port wine stains, which are larger flat birthmarks caused by a concentration of dilated capillaries in the skin; haemangiomas, which are benign overgrowths of blood vessels that typically appear in early childhood; cherry angiomas, which are small, bright red raised spots common from middle age onward; and telangiectasias, the clinical term for fine dilated capillaries visible on the skin surface.

Most vascular lesions in the aesthetic context are treated because of their cosmetic impact rather than any medical necessity. The presence of visible blood vessels on the face or body can create an uneven or reddened complexion, and in some cases, such as port wine stains, can be quite prominent and a significant source of self-consciousness. Professional treatment can dramatically reduce or eliminate many types of vascular lesion with a good safety profile when performed by an experienced provider.

The primary treatment approach for most vascular lesions in aesthetic practice is laser or intense pulsed light therapy. These treatments work by targeting the pigment in red blood cells within the vessel, converting the light energy to heat that damages the vessel wall and causes it to collapse and be reabsorbed by the body over the following weeks. The specific laser or device used depends on the type, size, and depth of the vessel.

What to Expect

For laser or IPL treatment of vascular lesions, protective eyewear is provided throughout. A cooling gel may be applied to the skin surface and the device delivers pulses of light energy to the treatment area. The sensation is typically a brief warm snap or sting with each pulse, similar to the feeling of a small elastic band against the skin. Most people find it well tolerated, though sensitivity varies with the size and depth of the vessels being treated.

After treatment, some redness and mild swelling in the treated area is normal and typically settles within a few hours to a day. Larger vessels may bruise slightly as they are damaged by the treatment. Thread veins and capillaries often appear temporarily darker or more prominent immediately after treatment before fading over one to two weeks as the body reabsorbs the damaged vessel walls.

Smaller, more superficial lesions such as thread veins and small spider veins often show significant improvement or complete clearance from a single treatment session. Larger or deeper lesions such as port wine stains typically require a course of multiple sessions to achieve the best result, and complete clearance may not always be achievable. Sun protection after treatment is important to protect the healing skin.

Who It’s For and Results

Treatment for vascular lesions is appropriate for anyone bothered by the visible appearance of blood vessels on the face or body, whether these are isolated thread veins, widespread redness from rosacea, a prominent birthmark, or the scattered red spots that develop with age. Vascular lesion treatment is purely elective and based on cosmetic preference rather than medical need for most benign lesions.

Results vary by lesion type and size. Fine thread veins and small spider veins respond very well to laser and IPL treatment and can often be substantially cleared within one to three sessions. Port wine stains and larger or deeper lesions require more sessions and may achieve significant lightening rather than complete clearance. Cherry angiomas typically respond very well to a single targeted laser treatment.

Skin tone affects treatment planning. Lighter skin tones with clearly visible contrast between the red vessel and the surrounding skin are the most straightforward to treat. In darker skin tones, the contrast is lower and the risk of the treatment affecting surrounding pigmentation is higher, requiring careful device selection, settings adjustment, and an experienced provider.

Frequently Asked Questions: Vascular Lesions

Both vascular lesions and pigmentation affect the colour of the skin surface but through different mechanisms. Vascular lesions are caused by visible blood vessels, giving affected areas a red, pink, or purple colour. Pigmentation is caused by excess melanin, giving affected areas a brown or grey discolouration. The two can coexist and both respond to light-based treatments, but different wavelengths are used to target each. IPL is particularly versatile because it can address both in the same session using different filter settings.

Not all vascular lesions can be completely cleared, though most can be significantly improved. Fine thread veins and small spider veins respond very well and often clear completely with treatment. Port wine stains, which involve a dense concentration of deep vessels, can be substantially lightened but complete clearance is not always achievable, particularly in older and darker lesions. The response also depends on the individual’s skin type, the location of the lesion, and how many treatment sessions are completed. Realistic expectations about the degree of improvement possible for a specific lesion type are an important part of the consultation process.

This depends on the type and size of the lesion. Small, superficial thread veins and spider veins often show a good response from one to three sessions. Larger or more complex lesions such as port wine stains typically require six or more sessions to achieve the best result, and in some cases ongoing maintenance is needed as residual vessels can become more apparent over time. A provider will give an indication of the expected number of sessions based on the specific lesion type and the initial response to treatment.

Laser and IPL treatments for vascular lesions are generally safe and well tolerated when performed by a qualified and experienced provider using appropriate equipment and settings. The main risks include temporary redness and bruising, rare pigmentation changes particularly in darker skin tones, and very occasionally scarring if settings are inappropriate. Choosing a provider with specific experience in vascular treatments and in treating diverse skin tones is the most important safety measure. A patch test before treating a larger area is often recommended for those with medium to deeper skin tones.
