Vascular & Pigmented Lesions in Côte Saint-Luc, Montreal

Laser treatment of vascular and pigmented lesions is a targeted aesthetic procedure that uses specific light wavelengths to selectively treat skin imperfections related to blood vessels (vascular lesions) and melanin (pigmented lesions). Unlike global skin rejuvenation that treats the entire face, this treatment focuses precisely on individual lesions to eliminate them in a targeted and effective manner.

Vascular lesions include broken capillaries (telangiectasias), facial varicosities, cherry angiomas (small red dots), rosacea-related redness, and spider veins. These lesions form when small blood vessels under the skin dilate or rupture, becoming visible through the skin. They can be caused by aging, sun exposure, genetics, hormonal changes, rosacea, or skin trauma.

Pigmented lesions include solar lentigines (sun spots), age spots, darkened freckles (ephelides), focal hyperpigmentation, and certain types of flat naevi (moles). These lesions result from localized overproduction of melanin, often caused by cumulative UV exposure.

The treatment works on the principle of selective photothermolysis: the laser emits a specific wavelength that is preferentially absorbed by the target chromophore — hemoglobin for vascular lesions or melanin for pigmented lesions. The absorbed energy is converted to heat, selectively destroying the lesion without damaging surrounding tissue. For vascular lesions, heat coagulates the blood vessel, which is then naturally reabsorbed by the body. For pigmented lesions, excess melanin is fragmented and eliminated by the lymphatic system.

At Réhabital in Côte Saint-Luc, our SharpLight Rapid DPC Pro system offers multiple wavelengths perfectly suited to each type of lesion. The Nd:YAG (1064nm) penetrates deeply to treat deeper vessels, while short-wavelength IPL filters effectively target superficial pigmented lesions. This versatility allows our technicians Liliana and Elena Ebrahimi to treat different types of lesions in a single session, delivering comprehensive, harmonious results.

Treatment precision is one of its main advantages: your technician can target lesions as small as one millimeter in diameter, preserving surrounding healthy skin. The built-in contact cooling system protects the epidermis and ensures patient comfort throughout the procedure. Results are often visible immediately for vascular lesions (the vessel disappears before your eyes) and within 1 to 2 weeks for pigmented lesions (the spot darkens then naturally flakes off).

During your initial consultation at Réhabital, your technician carefully examines your lesions, identifies them (vascular vs pigmented), and determines the optimal treatment protocol. Some lesions require a prior medical examination to rule out any pathology — in that case, your technician will refer you to a dermatologist.

On treatment day, the area is cleansed and a conductive gel is applied. your technician selects the appropriate wavelength and parameters based on the lesion type: Nd:YAG for vessels, filtered IPL for pigments. The applicator is positioned precisely on the lesion and one or more pulses are delivered. For broken capillaries, you'll often see the vessel disappear immediately — an instantly gratifying result.

For pigmented spots, the lesion may darken slightly immediately after treatment (fragmented melanin rises to the surface). Over the following 7 to 14 days, a thin crust may form and naturally fall off, revealing clear skin underneath. Most lesions require 1 to 3 sessions depending on their size and depth. Treatment is quick — 15 to 20 minutes — and you can resume normal activities immediately.
