Sclerotherapy

BEFORE & AFTER

Every Result Has a Story

Before and after Sclerotherapy results at PI Aesthetics Medical Spa in Mill Creek, WA.

Treatment type: Sclerotherapy

Patient Concerns: Prominent spider veins on her legs had quietly changed the way she dressed and the choices she made without fully realizing it at first. Short dresses stayed in the closet. Swimwear felt uncomfortable. She had spent years covering up something she resented having to cover, and she was done with it.

Treatment Plan: We designed a personalized sclerotherapy plan tailored to her specific veins and her goals. She chose to start with the most prominent vessel before committing to a full leg treatment, and we built her plan around that decision, treating the largest vein first to give her a clear picture of what was possible before moving forward with the rest.

Results: After a single session, the largest vessel has essentially disappeared. The photo you are seeing captures just the beginning of her treatment journey. She is already looking forward to addressing the remaining veins, and for the first time in years, she is thinking about what she wants to wear rather than what she needs to hide.

I had an absolutely incredible experience at PI Aesthetics! Thoa is knowledgeable, personable, kind, and just overall so skilled at what she does. I went to her for my first Botox experience, and I had no idea what to expect. She took the time to thoroughly explain things to me and made me feel super comfortable. The whole thing was so seamless. I’ve come back to her for laser hair removal and some additional skin care treatments, and I’m super happy with all of my results. She has a great way of educating/explaining your options without pressuring you into doing anything you’re not ready for. Plus, she truly makes you feel like she’s known you for years. I will never go anywhere else :)

"Sclerotherapy is one of those procedures where precision is everything. I like to put on my surgical loupes for most sclerotherapy treatments. Some of these vessels are remarkably small and getting a needle placed accurately into them requires complete focus and a steady hand. There is something deeply satisfying about watching the sclerosing agent fill a vessel and knowing it simply has no chance against it. It will eventually collapse, fade, and be gone over the following weeks to months”

"Hearing patients tell me that this treatment changed their life is truly one of the most rewarding things I experience. I have had patients who would not wear a skirt because they were ashamed of how their legs looked. That hurts my heart, and I will not stand for it. My goal is to have every single one of them showing off their clear legs in a bright colored skirt by next spring. Score: Spider Veins 0 - Clear Beautiful Legs 1."

What our doctors have to say about sclerotherapy

FAQs

Frequently asked questions

What is sclerotherapy?

Sclerotherapy is a medical treatment for spider veins and small varicose veins performed outside of the face, most commonly on the legs. A sclerosing agent is injected directly into the affected veins, causing them to collapse and be gradually reabsorbed by the body.

What concerns can sclerotherapy treat?

Sclerotherapy is effective for spider veins and small varicose veins, most commonly on the legs.

How is sclerotherapy different from laser treatment for spider veins?

Both treatments are effective for spider veins but work differently and are suited to different situations. Sclerotherapy uses a sclerosing agent injected directly into the vein, making it particularly effective for larger spider veins and small varicose veins on the legs. Laser treatment uses light energy applied to the surface of the skin and is generally better suited for smaller, finer vessels and facial vascular concerns. In some cases, a combination of both approaches delivers the best outcome. Your doctor will help you determine the most appropriate treatment during your consultation.

How many sessions will I need?

Most patients require between 2 and 4 sessions to achieve their desired result, though this depends on the extent and size of the veins being treated. Sessions are typically spaced several weeks apart to allow the treated veins to fully respond before the next treatment. Your doctor will give you a realistic estimate during your consultation.

What is the cost?

Cost depends on the number of veins being treated and the number of sessions required. The cost of a single session ranges from $300 to $750, depending on the area being treated. Your doctor will provide an accurate estimate during your consultation once your treatment plan is established.

What are the risks?

Like all medical treatments, sclerotherapy carries known risks. We address these thoroughly during your consultation so you can make a fully informed decision. Our team is specifically trained to manage possible complications, and we approach every treatment with a high degree of clinical care and thoughtfulness.

Am I a good candidate for sclerotherapy?

Most patients with spider veins or small varicose veins on the legs are good candidates for sclerotherapy. However, certain conditions may affect candidacy. An in-person assessment is the best way to determine whether sclerotherapy is the right treatment for your specific concern.

What should I avoid before my treatment?

In the days before your treatment we recommend avoiding alcohol and, if medically able, NSAIDs such as ibuprofen and other medications that can increase bleeding. We also recommend avoiding sun exposure to the treatment area. Your doctor will provide specific preparation instructions during your consultation.

What should I expect after treatment and is there any downtime?

After treatment you may experience mild bruising, redness, and temporary darkening of the treated veins, which is a normal part of the process. Compression stockings are typically recommended after treatment to support the healing process. Most patients are able to return to normal activities the same day, though strenuous exercise should be avoided for a short period. Your doctor will provide detailed aftercare instructions following your treatment.

When will I see results?

Treated veins gradually fade over several weeks to months as the body reabsorbs them. Some veins may darken initially before fading, which is a normal response to treatment. Full results are typically visible within 3-6 months after each session. Your doctor will set realistic expectations during your consultation based on your specific treatment plan.

Your Consultation Is Where It All Starts

Before any treatment is discussed, your doctor sits down with you. Not a coordinator, not a patient intake manager. Your doctor.

Your doctor will begin by taking the time to understand what brought you in and what you are hoping to achieve. From there they will perform a comprehensive facial assessment, evaluating your unique anatomy, facial profile, skin condition, and movement patterns. They will share their findings, walk you through what they are seeing, and make sure you leave with a clear understanding of your options. This is not a formality. It is the foundation of everything that follows, because a plan that is right for someone else may not be right for you. We do not rush this part.

From there we walk you through your options honestly, discuss what we believe is appropriate, and build a personalized plan around your goals. We only recommend what we genuinely believe in, and we hold ourselves to the same standard we would expect for our own family.

You will leave with clarity, a plan you feel confident in, and every question answered. Whether you proceed with a treatment that day or not, you will leave informed.

Overview

Spider veins are one of those concerns that tend to grow quietly in the background until one day they are simply impossible to ignore. For many patients it is not a dramatic moment but a gradual shift, choosing pants over shorts, skipping the swimsuit, thinking twice before crossing your legs in a meeting. The concern is specific, the frustration is real, and the good news is that it is treatable.


Sclerotherapy is a medical treatment in which a sclerosing agent is injected directly into affected spider veins and small varicose veins, causing them to collapse and be gradually reabsorbed by the body. It is one of the most reliable and clinically proven treatments available for this specific concern, particularly for larger spider veins and small varicose veins on the legs where laser treatment alone may not be the most effective approach. In some cases a combination of both delivers the best outcome, and your doctor will guide that decision during your consultation.


Every sclerotherapy treatment at PI Aesthetics is performed by our doctors. Results develop gradually over several weeks to months as the treated veins fade and the body completes the reabsorption process. Most patients return to their normal activities the same day, and your doctor will give you a clear and honest picture of what to expect before you commit to anything.
