CLaCS Treatment
The procedure consists of the combined application of a transcutaneous laser and injections of a liquid, with the aid of a cooler with a continuous flow of cold air that offers greater comfort to the patient.
The physical action of the cold air and the technique used will collapse the vein and also destroy the wall of the diseased vessel.
To enhance results, VeinViewer is used, an augmented reality technology that emits infrared rays to project onto the skin veins that are invisible to the naked eye but are the source of visible spider veins. This device also allows treatment of the veins that feed the veins visible on the surface of the skin.
It is a non-invasive and non-aggressive treatment for the body.
Contraindications
This technique may be indicated for a large percentage of patients who wish to treat spider veins.
However, prior to any treatment, a consultation and assessment must be carried out.
If you are pregnant, and since this is a time when spider veins is likely to develop, it is best to wait until 6 months after delivery to obtain more promising results.
