If you've started researching leg vein treatment, you've probably run into two terms over and over: sclerotherapy and laser treatment. Comparing sclerotherapy vs laser vein treatment can feel confusing at first, especially because "laser" actually covers two quite different procedures at Melbourne Leg Vein Centre, surface laser, which treats veins from outside the skin, and endovenous laser ablation (EVLA), which treats veins from inside them. Add sclerotherapy's own two forms (surface and ultrasoundguided) and it's easy to see why people arrive at their first consultation unsure which option applies to them.

This guide walks through how each treatment actually works, which type of vein each one suits, and the practical differences in pain, downtime, sessions and cost, including Medicare rebate eligibility. It's general information to help you prepare for a consultation, not a diagnosis. Every leg is different, and one of MLVC's doctors will only recommend a specific treatment after examining your veins, in many cases using ultrasound to see what's happening beneath the surface.

How Sclerotherapy Works

Sclerotherapy is an injection-based treatment. A fine needle is used to inject a solution directly into the vein, which irritates the vein wall, causing it to collapse and eventually be reabsorbed by the body and fade from view over the following weeks.

MLVC offers two forms of sclerotherapy:

• Surface sclerotherapy: used for spider veins and reticular veins visible at the skin's surface, where the vein can be targeted by eye.

• Ultrasound (guided) sclerotherapy: which uses real-time ultrasound imaging to guide injections into larger or deeper veins that can't be seen or safely treated by sight alone, including some varicose veins.

How Laser Treatment Works (Two Different Procedures)

This is the point where a lot of the online confusion starts. "Laser" is not one treatment, it's a mechanism (using light or heat energy) that MLVC applies in two distinct ways depending on where the problem vein sits.

• Surface Laser Vein Treatment: Surface laser vein treatment is applied to the outside of the skin. The laser targets the pigment in blood within very fine, superficial spider veins and telangiectasia, heating and closing them without any needle or injection. It's a non-invasive option best suited to the finest surface vessels, particularly where injecting a needle would be impractical.

• Endovenous Laser Ablation (EVLA): Endovenous laser ablation is a completely different procedure despite the shared word "laser." Under ultrasound guidance, a thin laser fibre is inserted inside a larger, faulty vein (commonly the great or short saphenous vein) through a small entry point in the skin. The fibre heats the vein wall from within, sealing the vein shut. Blood then reroutes naturally through healthy veins, and the treated vein is gradually absorbed by the body. This is a treatment for the underlying "feeder" veins driving larger varicose veins, not for surface spider veins.

MLVC also offers two related endovenous options for larger veins, which your doctor may discuss alongside sclerotherapy and EVLA depending on your ultrasound findings: radiofrequency ablation (RFA), which uses heat generated by radiofrequency energy rather than laser light to close a faulty vein from inside, and endovenous medical glue (VenaSeal), which seals the vein using a medical adhesive instead of heat.

Which Treatment Suits Which Vein Type

The honest answer to "sclerotherapy or laser" is usually "it depends on the vein," not on one method being generally superior to the other. Each is suited to a different job. Fine spider veins and telangiectasia are typically suited to surface sclerotherapy or surface laser, depending on vessel size, colour and skin tone. Reticular veins (feeder veins) are typically suited to surface or ultrasound-guided sclerotherapy. Larger varicose veins with proven reflux are typically suited to ultrasound-guided sclerotherapy, EVLA, RFA or medical glue, chosen on ultrasound findings.

Sclerotherapy tends to be the more versatile of the two mechanisms because it can be scaled from a very fine surface vessel right up to a larger vein when guided by ultrasound. Surface laser is generally reserved for the finest vessels where a needle isn't the ideal tool, while EVLA (and its heat-free alternatives, RFA and medical glue) is reserved for the larger, deeper "source" veins that are often feeding the visible surface veins in the first place. Treating the underlying larger vein first, where one exists, is often why a doctor recommends EVLA, RFA or ultrasound sclerotherapy before addressing the smaller cosmetic veins on the surface.

Pain and Discomfort: What to Expect

Neither treatment is generally described as significantly more painful than the other, but the sensations differ. Sclerotherapy involves a series of small injections, and most people describe the sensation as a brief sting or pinch at each injection point, with some mild cramping possible if the solution reaches a larger vein. Surface laser involves a warm, snapping sensation on the skin with each laser pulse, similar to a light elastic band flick, with no needles involved. EVLA is performed with local anaesthetic around the vein before the laser fibre is activated, so the ablation itself is not typically felt, though some soreness or a pulling sensation along the treated vein is common for a few days afterwards.

Pain tolerance is individual, and your doctor can talk through what to expect for your specific veins at consultation.

Downtime and Recovery Differences

Recovery expectations differ mainly by how deep the treated vein sits, not by whether the treatment involved a needle or a laser. Surface sclerotherapy and surface laser involve minimal downtime, and most people resume normal daily activities the same day, though some bruising, redness or temporary discolouration at treatment sites is common and settles over one to a few weeks. Ultrasound-guided sclerotherapy has similar minimal downtime, generally with compression stockings recommended for a period afterwards to support the treated vein as it closes. EVLA, RFA and medical glue are also outpatient procedures with same-day discharge, but because a larger, deeper vein has been treated, doctors typically advise wearing compression stockings for a period after the procedure and easing back into strenuous exercise gradually. Most people are back to normal light activity within a few days.

How Many Sessions Are Typically Needed

Session numbers vary by vein size, extent and how the vein responds, and MLVC's doctors will give you a personalised estimate rather than a fixed number. Sclerotherapy for spider and reticular veins is often done as a course of several sessions spaced weeks apart, since each session targets what's visible and further sessions address fading or newly visible vessels. Surface laser similarly may involve multiple sessions for full coverage of an area of fine surface veins. EVLA, RFA and medical glue are generally single-procedure treatments per vein, since the goal is to seal one specific larger vein in one sitting. Sclerotherapy may still be used afterwards to address any remaining smaller surface veins once the larger source vein is dealt with.

Cost and Medicare Rebate Differences

This is one of the most practical differences between the two approaches, and it comes down to vein size and whether the vein qualifies under Medicare rules rather than which "type" of treatment it is.

Under Medicare item 32500, a rebate applies to injection sclerotherapy of veins over 2.5mm in diameter, using continuous compression technique, where proximal reflux has been demonstrated on ultrasound and the treatment is not cosmetic. This item is capped at 6 treatments per 12-month period. The schedule fee is $131.45, with a rebate of $98.60 (75%) or $111.75 (85%), and an Extended Medicare Safety Net cap of $144.60. Item 32500 does not cover sclerotherapy delivered as part of EVLA, RFA or medical glue procedures.

Veins under 2.5mm, such as most fine spider veins, don't qualify for this rebate and are treated as a cosmetic procedure, which also attracts GST.

Larger varicose veins treated with EVLA or RFA may be eligible for a separate Medicare Benefits Schedule rebate under different item numbers, though an out-of-pocket cost typically still applies. Your doctor and the MLVC team can talk you through the likely costs for your specific veins once an assessment has been done. For general pricing information, see the fees page.

How MLVC's Doctors Decide What's Right for You

You don't need a GP referral to book a consultation with one of MLVC's doctors, Dr Tim French or Dr Garth Dicker. A referral is only required if a detailed vein-mapping ultrasound scan is needed and you want to claim a Medicare rebate on that scan.

At consultation, your doctor examines your legs and, where indicated, uses ultrasound to look beneath the skin at how blood is flowing through the vein system. This is important because spider veins on the surface are sometimes being "fed" by a larger, deeper vein that isn't visible to the eye. Treating only the visible spider veins without addressing that underlying source can mean the surface veins are more likely to return.

Based on vein size, depth, location and whether reflux is present, your doctor will recommend an approach, which might be a single treatment type or a staged combination (for example, EVLA or RFA for a larger source vein, followed by sclerotherapy for the remaining surface veins). You can read more about how leg veins develop on the about leg veins page, or browse the full range of options on the leg vein treatments hub.

Frequently Asked Questions:

Is sclerotherapy or laser treatment better for spider veins?

For most fine spider veins, both surface sclerotherapy and surface laser vein treatment can be appropriate, and the choice often comes down to vessel size, colour, skin tone and personal preference around needles versus light-based treatment.

Neither is universally better for every case; it's a suitability decision your doctor makes after examining your veins

What's the actual difference between sclerotherapy vs laser vein treatment?

Sclerotherapy uses an injected solution to collapse a vein from the inside via chemical irritation, while laser treatment uses light or heat energy, either applied to the skin surface or via a fibre inserted into the vein, to close it. Some larger veins are treated with laser fibres inserted internally (EVLA), which is a different procedure again from surface laser used on visible spider veins.

Can EVLA and sclerotherapy be used together?

Yes. It's common for a larger underlying vein to be treated with EVLA, RFA or medical glue first, with ultrasound-guided or surface sclerotherapy used afterwards for any remaining visible surface veins once the source vein has been closed.

Does Medicare cover sclerotherapy or laser vein treatment?

Medicare item 32500 provides a rebate for injection sclerotherapy of veins over 2.5mm where proximal reflux has been demonstrated on ultrasound and treatment is non-cosmetic, capped at 6 treatments per 12-month period. Veins under 2.5mm don't qualify and attract GST. Larger varicose veins treated by EVLA or RFA may attract a separate MBS rebate, though out-of-pocket costs typically still apply.

How many sessions of sclerotherapy or laser treatment will I need?

This depends on the size and extent of your veins. Spider and reticular vein treatment with sclerotherapy or surface laser is often done over several sessions, while EVLA, RFA and medical glue are typically single procedures per vein. Your doctor can give you a clearer estimate after an assessment.

Do I need a referral to see someone about my leg veins at MLVC?

No referral is needed to book a consultation. A referral is only required if you need a detailed vein-mapping ultrasound scan and want to claim a Medicare rebate on that scan specifically.

Conclusion

When it comes to sclerotherapy vs laser vein treatment, there isn't a single winner, only the option (or combination of options) suited to the specific veins on your legs. Sclerotherapy is the more versatile injection-based option, scaling from fine surface vessels to larger veins under ultrasound guidance. Surface laser suits the finest visible spider veins, while EVLA (along with RFA and medical glue) is reserved for larger, deeper source veins found through ultrasound. The most reliable way to know which applies to you is a consultation with one of MLVC's doctors, no GP referral required, where an assessment (and ultrasound if needed) will guide the recommendation. You can book an appointment directly, or read more on the leg vein treatments hub beforehand.
