Spider veins – those fine, web-like red or blue veins that often appear on the legs or face – are a common cosmetic concern for many people. While they might seem like surface-level issues, the true cause of spider veins often lies deeper beneath the skin. One of the most critical yet frequently overlooked factors in achieving effective and lasting results is the proper treatment of feeder veins, also known as reticular veins.
What are feeder veins?
Feeder veins are slightly larger, bluish-green veins located just under the skin. They are not always visible to the naked eye, but they act as the “source veins” supplying blood to the smaller spider veins that branch out from them. When feeder veins are left untreated, they continue to pump blood into the spider veins, which can lead to poor results, early recurrence, and ongoing cosmetic concerns.
Why Treating Spider Veins Alone Isn’t Enough
Many people seek treatment for spider veins thinking a surface-level approach – such as laser or sclerotherapy directly on the visible veins – will be enough. While these methods can improve the appearance temporarily, ignoring the feeder veins is like painting over damp walls without fixing the leaking pipe behind them.
Here’s why:
Untreated feeder veins continue to refill spider veins, leading to recurrence.
The root cause is left unaddressed, making treatments less effective and more short-lived.
Patients may require repeated treatments, increasing time and cost without long-term satisfaction.

While spider veins may be the most noticeable concern, they’re often just the symptom of a deeper issue: underlying feeder veins. These hidden reticular veins act as the source, constantly supplying blood to the surface spider veins. Failing to identify and treat them is like trimming branches while ignoring the roots—they’ll just grow back. By shifting the focus from the obvious (the “tree”) to the underlying cause (the “forest”), patients can achieve more effective, longer-lasting results that address both appearance and the actual vein dysfunction.
The Benefits of Treating Feeder Veins First
Targeting feeder veins as part of a comprehensive spider vein treatment plan offers multiple advantages:
Improved long-term outcomes – Treating the underlying source helps prevent the spider veins from returning.
More even cosmetic results – Reducing pressure in the feeder veins means fewer new spider veins form over time.
Fewer treatment sessions – Addressing the source early can reduce the need for repeated touch-ups.
How Are Feeder Veins Treated?
Feeder veins are typically treated using a technique called ultrasound-guided sclerotherapy. Unlike basic surface treatments for spider veins, this method allows the practitioner to locate and target the underlying reticular or feeder veins that aren’t always visible to the naked eye. Using ultrasound imaging, a trained provider can precisely inject a sclerosing solution into the feeder vein. This solution irritates the vein lining, causing it to collapse and eventually be reabsorbed by the body. As blood is redirected to healthier veins, pressure on the surface spider veins is reduced, which helps prevent recurrence.
This treatment is minimally invasive, requires no surgery, and can often be completed in under 30 minutes, depending on the number and size of feeder veins involved. Most patients can return to their normal activities the same day, although compression stockings may be recommended for a short period afterward to enhance healing and results. By combining ultrasound guidance with targeted sclerotherapy, practitioners can effectively address the root cause of spider veins, leading to smoother, more consistent outcomes and fewer repeat treatments over time.
The Bottom Line
If you’re considering treatment for spider veins, make sure your provider assesses and treats the feeder veins too. It’s the difference between a temporary fix and a lasting solution. At Laurel Clinical, our vein doctor take a comprehensive approach, targeting both the visible spider veins and their deeper sources to give you results that are not just noticeable – but sustainable.
