If you’ve noticed clusters of red, blue, or purple veins spreading across your legs, calves, or thighs, you’re not alone. Spider veins (also called telangiectasias) affect up to 55% of women and 45% of men at some point in their lives. For most people, summer is the season that makes them finally act: shorts, swimsuits, and bare legs put spider veins in plain view. At Laser Clear Skin MedSpa in San Francisco, our RN-led team offers sclerotherapy, the gold-standard spider vein treatment, with free medical-grade compression stockings included with every session.
Whether you’re dealing with a handful of visible veins on one leg or an extensive network across both, this guide covers everything you need to know before booking: what causes spider veins, how sclerotherapy works, what the treatment actually feels like, how many sessions you’ll need, what it costs in San Francisco, and why now is the best time to start. By the end, you’ll know exactly what to expect, and exactly where to go.
What Are Spider Veins: Causes, Risks, and What to Kno
Spider veins are small, dilated blood vessels that sit close to the surface of the skin, forming web-like or branching patterns in shades of red, blue, or purple. They appear most often on the legs and face. Unlike varicose veins (which are larger, raised, and rope-like) spider veins are flat and generally don’t cause serious circulatory problems. But they can cause aching, burning, itching, or leg fatigue in the affected area, and for many people, eliminating them is as much about comfort as appearance.
Several factors contribute to spider vein formation:
- Genetics: If your parents or grandparents had spider veins, your risk is significantly higher. Family history is one of the strongest predictors.
- Hormonal changes: Pregnancy, birth control pills, hormone replacement therapy, and menopause all increase the likelihood of spider vein development by affecting blood vessel walls.
- Prolonged sitting or standing: Jobs or lifestyles that require long periods in one position (whether behind a desk or on your feet) create pressure in the leg veins over time.
- Sun exposure: UV damage is the leading cause of spider veins on the face and nose. Years of sun exposure breaks down collagen in vessel walls, making them more prone to dilation.
- Age: Vein walls and valves weaken naturally as we age, making blood less efficient at flowing upward from the legs. This allows small vessels to dilate and become visible.
- Weight and lifestyle: Excess weight increases venous pressure in the legs, and low physical activity means less help from the calf muscle pump that moves blood back toward the heart.
The good news: regardless of the cause, spider veins are highly treatable. The American Academy of Dermatology recognizes sclerotherapy as the most effective first-line treatment for leg spider veins, and it’s exactly what we offer at Laser Clear Skin.
Sclerotherapy: The Gold Standard for Spider Vein Treatment in San Francisco
Sclerotherapy has been the gold standard for spider vein treatment for decades, and for good reason: it’s safe, minimally invasive, highly effective, and requires no downtime. The procedure involves injecting a medical-grade sclerosing solution (typically a salt-based or foam formula) directly into the affected vein with a very fine needle. The solution irritates the inner lining of the vessel, causing it to swell shut and collapse. Over the following weeks, the body naturally reabsorbs the treated vessel, and it gradually disappears from view.
The entire session takes 30–45 minutes, requires no anesthesia, and is performed right in our North Beach clinic. Most patients drive themselves home and return to work or daily activities the same afternoon. At Laser Clear Skin, every sclerotherapy session includes free medical-grade compression stockings, a value most San Francisco clinics charge separately. These stockings are essential for optimal results: they support the treated vessels and improve circulation during healing.
For very fine or facial spider veins, laser vein therapy can be an effective alternative. However, sclerotherapy remains the preferred approach for the vast majority of leg veins because it works across a wider range of vein sizes and colors, and has a longer, more established track record. Your RN will assess your specific situation during the consultation and recommend the right approach.
What to Expect at Your Spider Vein Treatment Appointment
Knowing exactly what happens during a sclerotherapy session removes the anxiety that can come with any first visit. Here’s the step-by-step:
- Consultation and vein mapping: Your RN examines the treatment area, maps out the network of veins to treat, and reviews your medical history. This step ensures sclerotherapy is appropriate and confirms there are no contraindications.
- Positioning: You’ll lie down on the treatment table with your legs slightly elevated. The area is cleaned with antiseptic.
- Injections: Using a very fine needle, your nurse injects the sclerosing solution into each targeted vein. Most patients feel a mild sting or brief cramp at the injection site (similar to a small pinch) that passes within seconds.
- Compression: Immediately after treatment, medical-grade compression stockings are applied. You’ll wear these for several days to support the collapsed vessels and reduce the chance of new vein formation.
- Walk and go: Short walks immediately after your session actually help the treatment work; gentle movement promotes blood flow through healthier vessels. You’ll leave the clinic on your feet and go about your day.
In the first few days after treatment, it’s completely normal to see mild bruising, redness, or a temporary darkening of the treated veins (a response called hemosiderin staining). These side effects resolve on their own, typically within a few weeks.
How to Prepare for Your Appointment
A little preparation goes a long way toward making your sclerotherapy session comfortable and your results as strong as possible:
- Wear loose, comfortable clothing: You’ll be putting on compression stockings after treatment, so shorts or loose pants are ideal.
- Avoid blood thinners for 48–72 hours beforehand: This includes ibuprofen, aspirin, and fish oil supplements. These increase the risk of bruising. (Consult your doctor before stopping any prescribed medication.)
- Skip tanning beds and sun exposure: Treat the treatment area as if it’s sunburned; tanned skin can affect how the solution reacts and increase the risk of pigmentation changes.
- Skip moisturizer on your legs the day of: Clean, dry skin makes it easier to apply compression stockings post-treatment.
- Stay hydrated: Good circulation and hydration support optimal results.
Aftercare: What to Do (and Avoid) After Sclerotherapy
Post-treatment care is straightforward, and following it closely makes a real difference in your results:
- Wear your compression stockings: For 3–7 days post-treatment (your RN will advise the exact duration). This is the single most important aftercare step.
- Walk daily: Aim for at least two 15-minute walks per day in the week after treatment. Walking activates the calf pump and promotes healthy circulation.
- Avoid sitting or standing still for long periods: Take breaks to move around during the work day.
- No hot baths, saunas, or hot tubs for 1–2 weeks: Heat dilates blood vessels and can reduce the effectiveness of the treatment.
- Avoid direct sun on treated areas for 2–4 weeks: UV exposure on recently treated veins can cause pigmentation changes. Sunscreen and light cover-up are your friends.
- Skip strenuous exercise for 48–72 hours: Light walking is encouraged; heavy cardio, weightlifting, and high-impact activities should wait.
Some patients notice temporary darkening of treated veins (this is the body beginning to break down the vessel) and occasionally small lumpy areas under the skin (trapped blood, called coagula). These are normal and typically resolve within a few weeks. Your provider may lightly drain a coagulum at a follow-up visit if needed.
How Many Sessions Do You Need?
The honest answer is: it depends on your veins. Most patients need 2–4 sclerotherapy sessions for satisfactory clearance, with treatments spaced 4–6 weeks apart to give the body time to reabsorb the collapsed vessels between sessions.
Smaller, finer spider veins often improve dramatically after a single treatment. Larger networks, veins with significant feeder vessels (the larger reticular veins that supply spider veins), or widespread involvement across both legs typically require more sessions. A very common outcome is 70–80% clearance after the first session, reaching full satisfaction by session 3 or 4.
At your Laser Clear Skin consultation, your RN will assess the density and complexity of your veins, identify any feeder vessels that need to be treated first, and give you a realistic session estimate. We don’t oversell sessions; you’ll know what to expect before spending a dollar.
Spider Vein Treatment Cost in San Francisco
Spider vein treatment in San Francisco typically ranges from $250 to $600 per session, depending on the size of the treatment area and the complexity of the vein network. A small patch of veins on one lower leg costs less than a full bilateral leg treatment addressing multiple areas.
Sclerotherapy is cosmetic in nature and is not covered by health insurance in most cases. However, Laser Clear Skin’s membership and package plans can significantly reduce the per-session cost for patients who need multiple treatments, which most do. When you factor in the free compression stockings included with every session (a $30–$60 value most clinics charge separately), the total cost of care at Laser Clear Skin is highly competitive for San Francisco.
Ask about package pricing and current promotions during your consultation; our team is always transparent about pricing before any treatment begins.
Why Summer Is the Best Time to Start Treatment
There’s a common misconception that you can’t do sclerotherapy in summer. You absolutely can, with one simple rule: keep treated skin protected from direct sun for 2–4 weeks post-session (easy to do with light clothing and SPF). Starting now means:
- Your results will be visible by late summer and early fall, right when most patients want clear skin.
- You’ll complete multiple sessions before the holidays and be ready for next year’s swimsuit season.
- Providers are busier in fall and winter when people plan for spring. Booking now means shorter wait times and better appointment availability.
- Summer motivation is real: using it while it’s fresh leads to better follow-through on completing a full treatment series.

Frequently Asked Questions About Spider Vein Treatment in San Francisco
Does spider vein treatment hurt?
The injections involve a mild sting or brief cramp at the needle site that passes within seconds. No anesthesia is needed, and most patients are surprised by how manageable the discomfort is. Post-treatment soreness is minimal and typically resolves within 24 hours. Most people return to work the same afternoon.
How long does it take to see results from sclerotherapy?
Treated veins begin fading within 3–6 weeks as the body absorbs the collapsed vessels. Full clearance typically takes 3–4 months. Many patients see 50–70% improvement after their first session. Results continue developing in the weeks and months following each treatment.
Are spider veins the same as varicose veins?
No. Spider veins are small, flat, branching vessels that sit just below the skin surface. Varicose veins are larger, raised, and rope-like, often visible as bulging through the skin. Both can be treated with sclerotherapy, but varicose veins are first evaluated for underlying venous insufficiency (a valve problem in deeper veins), which may require additional assessment before treatment.
Will my spider veins come back after treatment?
The veins that are treated with sclerotherapy are permanently destroyed; they do not return. However, new spider veins can develop over time due to the same underlying factors (genetics, hormonal changes, lifestyle) that caused the original ones. Wearing compression stockings regularly and returning for maintenance sessions as new veins appear is the best long-term strategy.
How many sessions will I need for spider vein treatment in San Francisco?
Most patients need 2–4 sessions spaced 4–6 weeks apart to achieve satisfactory clearance. A small, simple cluster of veins may respond to a single session. A widespread network across both legs may require 4 or more. Your RN at Laser Clear Skin will give you a personalized estimate at your initial consultation, so you’ll know what to expect from the start.
