What Causes Spider Veins To Reappear After Laser Treatment?

Spider veins, those delicate red or blue networks that weave across the skin’s surface, can be a source of aesthetic concern for many individuals. Laser treatments have become a popular choice for addressing these unsightly veins, offering a non-invasive solution with promising results. However, a recurring question lingers in the minds of those who have undergone laser therapy: “What causes spider veins to do spider veins come back after laser treatment?” In this exploration, we delve into the intricacies of the phenomenon and seek to understand the factors contributing to the reappearance of spider veins post-laser treatment.

The Promise of Laser Treatment:


Laser treatment for spider veins has gained popularity due to its non-surgical nature and minimal downtime. The procedure involves directing focused laser energy onto the targeted veins, causing them to collapse and eventually fade from view. The initial success of the treatment often leaves individuals satisfied, but for some, the relief is short-lived as spider veins may reappear over time.

Understanding the Physiology:

To comprehend why spider veins might return, it’s essential to delve into the underlying physiology of these vascular imperfections. Spider veins occur when small blood vessels near the surface of the skin dilate, resulting in a visible web-like pattern. Laser treatments aim to eliminate these dilated vessels, but various factors can contribute to their resurgence.

Incomplete Treatment:

One common reason for the reappearance of spider veins is incomplete treatment during the initial laser session. In some cases, not all affected vessels are successfully targeted, allowing untreated veins to persist and potentially give rise to new spider veins.

Genetic Predisposition:

Genetics play a crucial role in the development of spider veins. Individuals with a family history of vascular issues may be more prone to developing new spider veins even after successful laser treatment. Genetic factors influence the overall health and resilience of blood vessels, impacting their susceptibility to dilation and the formation of spider veins.

Hormonal Changes:

Fluctuations in hormone levels can also contribute to the reappearance of spider veins. Pregnancy, birth control pills, and hormonal therapies can affect the vascular system, making individuals more susceptible to the development of new spider veins, even after laser treatment.

Lifestyle Factors:

Certain lifestyle factors can undermine the efficacy of laser treatment and contribute to the recurrence of spider veins. Prolonged periods of standing or sitting, lack of exercise, and obesity can strain the vascular system, leading to the emergence of new spider veins over time.

Preventive Measures and Optimizing Results:

While the reappearance of spider veins is a possibility, there are preventive measures and strategies to optimize the outcomes of laser treatment.

Comprehensive Assessment:

A thorough pre-treatment assessment is crucial for identifying all affected veins and ensuring a more comprehensive laser treatment. This involves mapping the vascular network to address both visible and potential hidden spider veins.

Lifestyle Modifications:

Encouraging individuals to adopt a healthier lifestyle can contribute significantly to the prevention of new spider veins. Regular exercise, maintaining a healthy weight, and avoiding prolonged periods of sitting or standing can help alleviate strain on the vascular system.

Follow-up Sessions:

Scheduled follow-up sessions with healthcare professionals can address any new spider veins that may have developed since the initial laser treatment. These sessions allow for timely intervention and the continued improvement of the overall vascular appearance.


In the quest for smooth, vein-free skin, understanding the factors contributing to the reappearance of spider veins after laser treatment is paramount. From incomplete initial treatment to genetic predispositions and hormonal influences, a multifaceted approach is needed to address this common concern. By combining comprehensive assessments, lifestyle modifications, and follow-up sessions, individuals can enhance the effectiveness of laser treatments and minimize the likelihood of spider veins making an unwelcome return.
