Vascular Lesion

Vascular Lesion Laser Treatment in Toronto and Richmond Hill Clinics


Vascular lesion include any skin conditions that arise from or influence blood or lymphatic vessels, such as tumors, malformations, and inflammatory diseases. A vascular anomaly is any of a range of lesions from a birthmark to a large tumor. Lasers have become an integral part in the management of hemangiomas and vascular malformations of many types. Patient outcomes have improved with new discoveries in laser technology and technique.


Cutaneous vascular lesion include any skin diseases that arise from or influence blood or lymphatic vessels, such as tumors, malformations, and inflammatory diseases. While some vascular lesions are easily detected clinically using methods such as skin surface microscopy, others can be difficult to differentiate because many of them have similar dermoscopic features.

There are other ways to treat this issue, but the most popular method is using laser treatment for cutaneous vascular lesion. This treatment method has progressed significantly over the past 30 years

One of the most common applications of lasers in dermatology is the treatment of vascular lesion. Lasers have generally become the treatment of choice for vascular birthmarks such as hemangiomas and port-wine stains, and rosacea telangiectatica. The number of congenital and acquired vascular lesions that can be efficiently treated with lasers is growing.

Multiple cutaneous vascular lesion, including telangiectasias, port wine stains (PWS; sometimes known as port wine birthmarks), and infantile hemangiomas, are treated with lasers and intense pulsed light (IPL). During treatment, light energy absorption by intravascular oxyhemoglobin causes heating and coagulation of lesioned blood vessels. The type of light source employed, the clinical characteristics of the target lesion, and patient-specific factors all influence how vascular lesions respond to therapy (eg, skin color, patient age).

Although laser and IPL therapy can provide clinical benefits, the procedure is not without risks. If clinicians are not careful, injuries can result, involving areas such as the skin or eyes. The use of suitable equipment settings, skin cooling systems, and other safety measures reduces the occurrence of treatment-related injuries and adverse effects.

By employing an appropriate wavelength, pulse duration, and energy setting, laser irradiation can selectively kill certain targets (chromophores) within the skin. To prevent damage to adjacent structures, the pulse duration must be less than or equal to the chromophore’s targeted thermal relaxation time, i.e. the time required for the target to cool by half of its peak temperature following laser irradiation. Because the energy deposited in the tissue is restricted to specific locations, considerable thermal diffusion to surrounding skin is avoided.

Furthermore, because the wavelengths corresponding to absorption peaks for distinct skin chromophores, laser energy absorption can be concentrated without causing damage to surrounding structures. Because intravascular oxyhemoglobin is the targeted chromophore for vascular lesions, thermal damage is largely limited to cutaneous blood vessels. The major oxyhemoglobin absorption peaks are at 418, 542, and 577 nm, with the latter being optimum.

Who's at risk?

A typical candidate has diffuse redness (many fine blood vessels appearing) or specific troublesome linear blood vessels, or both. The face, particularly the nose, is the most typically treated area. The treatment may take up to a month to fully take effect, but the result is permanent. People who have an excess of blood vessels, on the other hand, may develop new vessels that will necessitate treatment in the future.

Vascular Lesion Treatment Procedure

There are various versions of a “normal session” in laser vascular lesion treatment, and what happens throughout the session varies on the technology utilized. If the treatment is uncomfortable, numbing cream is sometimes applied 30–90 minutes before the procedure. The patient will lie down on an exam bed and the area will be cleansed to remove any makeup before the treatment. Everyone in the room is required to wear eye protection once the treatment area has been identified and confirmed by the patient. Metal-lined adhesive pads, goggles, or eye shields either over or under the eyelid, are some of the eye protection options available to patients.

The doctor will next program the equipment with the necessary settings and select a hand-piece. The hand-piece is placed on the skin, and the pulse of laser energy is fired using either a trigger or a foot pedal, targeting a 1–3 cm area of skin. The feeling during the treatment is fleeting, and each laser pulse is commonly characterized as a warm pin-prick. Treatment timeframes vary depending on the size of the region to be treated and the equipment employed, but they typically last 15–30 minutes.

How to prepare for a vascular lesion laser session:

  • Avoid getting tanned — Stay out of the sun during the day, use sunscreen with a high SPF, and wear UV-protective clothing (eg, a hat and tightly woven clothing).
  • If necessary, apply numbing cream 30–90 minutes before the surgery.
  • Avoid drugs and supplements that increase the likelihood of bruising (only if quitting any of the following medications has been discussed with your doctor):
  • Aspirin
  • Ibuprofen
  • Vitamin E
  • Fish oil supplements
  • Prescription blood-thinning medications

What outcome should patients expect? 

Lesions may dissolve completely after 1-2 treatments or may require a series of treatments, depending on the condition. The patient must follow post-operative care requirements, such as limiting sun exposure and applying broad-spectrum sunscreen on a regular basis.

Success rates

Treatment techniques are frequently based on the patient’s skin type. There is a larger risk of problems with particular disorders or skin types. It is critical for the patient to do their homework ahead of time in order to find a practitioner who has the necessary skills and experience to perform the treatment.

Q & A for Vascular Lesion

Laser light penetrates the outer layers of skin to reach the blood vessels below. Targeted blood vessels selectively absorb the energy in the laser light and are destroyed by the brief, but intense heat created. The body removes the damaged vessels gradually to normalise the skin’s appearance. Surrounding tissue is unaffected because it does not selectively absorb this wavelength of light. Vascular lasers are the ideal treatment for blood vessels and red blemishes close to the surface of the skin, particularly on the face, neck, and chest.

Vascular laser treatment is non-invasive and feels like a series of quick stings, similar to a rubber band flicking on the skin. A sensation of heat that may persist for a few minutes after treatment.

Most treatments take just a few minutes to about half hour. How many treatments will I need for vascular lesion?
One or two treatments usually eliminate most common red blemishes, though certain conditions may require a course of treatments. Port wine birthmarks, for example, often require multiple treatments over many months.
