What is vascular laser?
A laser whose light is absorbed by haemoglobin, the red pigment in blood. The heat produced in the vessel closes it without reaching the surrounding skin; the body then reabsorbs it over a few weeks. Wavelength, pulse duration and cooling are set according to the size and depth of the vessel and the colour of the skin.
Which indications?
Broken capillaries and facial erythrosis (persistent redness of the cheeks and nose), the vascular component of rosacea, ruby angiomas (small raised red spots, common with age), spider angiomas (star-shaped), telangiectasias of the sides of the nose and chin, and small spider veins of the legs. Diagnosis always comes before treatment.
Rosacea: laser and core treatment
In rosacea, laser treats visible vessels and redness, but does not cure the disease. Flares of spots, skin sensitivity and inflammatory redness call for core medical treatment (suitable care, medicines), with which laser is combined. The rosacea page details this care.
Spider veins and varicose veins: what laser can and cannot treat
Laser treats small superficial vessels, fine "spider veins" (telangiectasias). Swollen, prominent veins, "varicose veins", are for a vascular doctor to assess, who may use a Doppler ultrasound, sclerotherapy or other techniques; they are not treated by laser alone. If your situation falls into this category, the dermatologist refers you.
The clinic's laser
The clinic has the Fotona SP Dynamis Nx Line platform, whose Nd:YAG is used for vascular lesions. Its wavelength penetrates deeper and is less absorbed by melanin, which allows olive skin to be treated more safely, with individualised settings and built-in cooling.
How a session goes
After consultation and cleaning of the area, goggles protect the eyes. The laser is passed over the targeted vessels, with a tingling or small rubber-band snap sensation, relieved by cooling. A session generally lasts 15 to 30 minutes. Transient redness of 24 to 48 hours is common; small scabs or bruises are possible and disappear within a few days.
How many sessions, what results?
One to three sessions are generally needed depending on the indication, extent and size of the vessels; improvement is often visible from the first. The laser treats the vessels present, not the predisposition: new vessels can appear over time, especially with sun exposure or rosacea, hence the value of maintenance and sun protection.
Precautions and contraindications
Avoid sun, tanning and UV before and after sessions, and apply sunscreen. Report photosensitising treatment, anticoagulant treatment, active herpes or damaged skin. Laser is postponed during pregnancy. The ideal time is autumn or winter, when the skin is less exposed to the sun.
Factors that favour redness
Sun, heat, sudden changes in temperature, certain prolonged topical treatments and family tendency favour redness and broken capillaries. The dermatologist advises on which care to favour and which to avoid, with a gentle routine and daily sun protection, particularly useful in Marrakech.
