Have you ever caught a glimpse of spider veins on your legs and thought, “When did those get there?” You’re not alone—and you’re certainly not without options. Whether you’re dealing with visible spider veins or small varicose veins that leave your legs feeling heavy or itchy, sclerotherapy could be exactly what you need to feel more confident and comfortable in your skin.
This treatment might sound complex, but it’s actually a straightforward, non-surgical procedure that’s been helping people for decades. In this guide, we’ll walk you through everything you need to know—from what sclerotherapy is and which conditions it treats to what happens before, during, and after treatment. If you’re looking for smooth, vein-free skin and wondering what the journey looks like, keep reading. We’ve got you covered.
Understanding Sclerotherapy
Sclerotherapy involves injecting a special chemical solution called a sclerosant directly into the problematic vein. This causes the vein to collapse and gradually disappear as the body reabsorbs it. The blood then reroutes through healthier veins.
Different types of sclerosants—such as sodium tetradecyl sulfate, polidocanol, or foam formulations—are chosen depending on the size and location of the vein. It’s a safe, well-tolerated treatment that improves both the appearance and the symptoms of problem veins.
Conditions Treated by Sclerotherapy
You might be surprised at the range of issues sclerotherapy can help resolve. Here’s what it’s commonly used for:
- Spider veins (telangiectasias) – Thin red, blue, or purple veins visible near the surface of the skin.
- Reticular veins – Slightly larger bluish veins located just under the skin.
- Small varicose veins – Bulging veins that may cause aching or throbbing.
- Early chronic venous insufficiency – When veins can’t return blood efficiently from the legs to the heart.
- Symptoms like leg fatigue, burning, itching, or swelling – Often linked to vein dysfunction.
It’s not meant for large, deep varicose veins, which may require treatments like endovenous laser therapy or surgery.
Ideal Candidates for Sclerotherapy
If you’re generally healthy and want to improve the look or feel of your legs, you might be a great fit. Sclerotherapy works well for:
- Adults with visible spider or small varicose veins
- People experiencing mild leg discomfort
- Non-smokers and those without blood clotting issues
- Those not currently pregnant or breastfeeding
- Individuals who haven’t had recent blood clots
A vein consultation can help determine whether you’re a good candidate or if another treatment would work better.
Before and After: What to Expect Over Time
Seeing the transformation unfold can be incredibly motivating. Here’s a general timeline of what you might expect:
- Days 1–3: Redness, mild swelling, or bruising is common. Treated veins may look darker initially.
- Week 1: Veins begin to close off and fade. You may notice firmness or lumpiness in some areas.
- Week 3: Bruising subsides and cosmetic improvement becomes visible.
- Week 6–8: Most veins have significantly faded.
- Month 3–6: Final results are visible. Additional sessions may be done for stubborn veins.
Remember, every person’s body responds a bit differently—so patience and aftercare are key.
Getting Ready for Your Appointment
Simple prep steps can make your treatment day easier and more effective:
- Stay out of the sun and tanning beds for a few days before.
- Avoid applying lotion, oil, or self-tanner on the treatment area.
- Tell your practitioner about any medications or supplements you take.
- Bring your compression stockings with you.
- Eat a light meal beforehand to avoid feeling faint.
What Happens During Sclerotherapy?
The actual treatment is quicker than you might think—usually just 30 to 45 minutes. Here’s how it works:
- Your practitioner will clean the area and possibly use ultrasound to locate deeper veins.
- A fine needle is used to inject the sclerosant directly into the vein.
- You may feel a slight sting or warmth, but discomfort is minimal and short-lived.
- Compression is applied right away to help the veins close properly.
- You’ll be encouraged to take a short walk immediately after the procedure.
What to Do After Your Treatment
The aftercare phase is just as important as the procedure itself:
- Wear compression stockings for at least two weeks.
- Walk daily to keep blood flowing.
- Avoid hot baths, saunas, or direct sunlight for 48 hours.
- Refrain from heavy exercise, alcohol, and standing for long periods for at least a week.
- Keep your legs elevated while resting.
Following these tips can help reduce side effects and speed up healing.
Healing Timeline: From Week 1 to 3 Months
Your body needs time to fully break down and reabsorb the treated veins. Here’s what that looks like:
- Week 1: You may feel minor cramping or itching. Some treated veins might look worse before they look better.
- Week 2: Discoloration and swelling begin to fade.
- Weeks 3–4: Skin texture improves. You may feel smoother, firmer skin.
- Week 6–8: Most treated spider veins are visibly reduced or gone.
- By 3 months: Final results are apparent. Additional sessions may be considered.
How Long Will the Results Last?
Here’s the good news—once a treated vein fades, it’s gone for good. But your body may form new veins over time, especially if you have an underlying tendency toward vein issues.
To maintain your results:
- Stay active
- Wear compression stockings when needed
- Avoid prolonged standing or sitting
- Maintain a healthy weight
Possible Side Effects and Risks
While sclerotherapy is generally safe, a few side effects can occur:
- Mild bruising or redness
- Temporary dark lines or spots
- Tiny clusters of new veins (matting)
- Itching or stinging at injection sites
Rare risks include:
- Allergic reactions
- Blood clots in deeper veins (DVT)
- Skin ulcers or infection
If you notice unusual warmth, swelling, or pain, contact your provider right away.
How Does Sclerotherapy Compare to Other Vein Treatments?
Here’s a quick overview:
- Sclerotherapy: Great for spider and small varicose veins. Minimal downtime.
- Laser therapy: Effective for surface veins. May cause more discomfort.
- Radiofrequency or laser ablation: Used for larger, deeper veins. More invasive.
- Vein surgery: Reserved for severe varicose veins. Requires recovery time.
For cosmetic and mild vein issues, sclerotherapy is often the best balance of results and convenience.
When’s the Best Time for Sclerotherapy?
Cooler months—like autumn and winter—are ideal. Why?
- Compression stockings are more comfortable.
- You’re less exposed to the sun, which can help prevent pigmentation.
- Your legs will be summer-ready by the time warm weather rolls around.
Common Areas Treated
Sclerotherapy can be performed on various body parts:
- Legs – Thighs, calves, and ankles are the most common.
- Face – For small veins on the nose and cheeks.
- Hands – To reduce signs of aging.
Facial sclerotherapy should always be done by experienced professionals due to the delicate skin and nerves in that area.
