The Nd:YAG laser treatment is primarily used to reduce the appearance of thread and spider veins. Nd:YAG laser penetrates deep into the skin to selectively target even the deepest skin structures such as deep-lying veins and hair follicles. It breaks apart unwanted particles, such as pigments, so that the body’s own immune system can remove them.
The laser penetrates the superficial blood vessel. The heat generated from the laser coagulates the blood inside the vessel, causing it to collapse and seal.
Over the next few weeks, the vessel will disappear and all the blood will be removed by the body’s scavenging cells. The modern laser treatments allow delivery of a precise dosage of energy to each blood vessel without injuring any nearby structures. Patients will feel mild discomfort during the treatment.
After the procedure, you may feel a slight bump on the skin; it should disappear a few hours after treatment. The area may also appear slightly redder and occasionally may be bruised.
The results of laser treatment for spider veins is not immediate. After the laser therapy, the vessels underneath the skin will gradually change from a dark blue to a light red colour as you can see on the video, then eventually fade in two to six weeks.
Between 2 – 6 sessions are recommended and they should be spaced four to six weeks apart. If new veins appear, additional treatments are required for optimum results.
The majority of patients report a high degree of satisfaction with the procedure and are happy to no longer hide unsightly veins. The treated areas are noticeably clearer and in most cases the skin continues to improve with each successive treatment.
