Sclerotherapy for Leg Veins in North Sydney
What is sclerotherapy?
Sclerotherapy is a medical treatment for certain visible leg veins, such as small varicose or spider veins, in which a solution is injected into the vein to reduce its appearance over time. It is performed by a qualified medical doctor after a consultation, and results develop gradually and vary between individuals.
Many people are bothered by small, visible veins on the legs, whether fine web-like spider veins or slightly larger surface varicose veins. Sclerotherapy is a non-surgical option used to help reduce the appearance of certain suitable veins. During treatment, a solution is injected into the targeted vein using a very fine needle, prompting the vein to gradually fade as the body reabsorbs it. Sclerotherapy is not appropriate for every vein condition, and some conditions require different medical care. For this reason, a doctor’s assessment comes first, to confirm whether the treatment is suitable for you and to explain the potential risks and aftercare.Considering sclerotherapy for leg veins in North Sydney?

How does sclerotherapy work?
Sclerotherapy works by treating the vein from the inside. A small amount of solution is injected directly into the targeted vein, irritating the lining of the vein wall so the vein closes and stops carrying blood. Over the following weeks and months, the body gradually reabsorbs the treated vein and its appearance fades. Blood that previously travelled through it simply reroutes through other, healthier veins nearby.Because the change happens as the body reabsorbs the vein, the result is gradual rather than immediate, and it varies from person to person depending on the size and number of veins treated. Some veins respond to a single session, while others need a course of treatments spaced over time. It is a non-surgical treatment, performed in the clinic, with no general anaesthetic. Your doctor will assess your veins and explain what a realistic outcome looks like for your situation before any treatment goes ahead.Which veins can be treated?
Sclerotherapy may be suitable for certain smaller surface veins on the legs, but it is not appropriate for all vein conditions. Some veins and underlying circulation issues require different medical care, which is one of the reasons a thorough assessment is essential. Areas and vein types that may be discussed at your consultation include:- Fine spider veins, the small web-like or branching veins close to the skin’s surface
- Smaller surface varicose veins that are suitable for injection
- Clusters of small visible veins on the legs that affect appearance
What happens at your appointment?
Your first appointment begins with a consultation. Under the 2025 AHPRA cosmetic guidelines, a consultation with a qualified practitioner is required before treatment. There is no obligation to proceed.A typical appointment involves:- A discussion of your concerns and what you would like to achieve
- An examination of the veins on your legs to assess which, if any, are suitable
- A clear explanation of what the treatment can and cannot do, the likely results, and the risks
- A personalised plan and quote, which you are free to consider before deciding
What results can you expect, and when?
Results from sclerotherapy develop gradually, over weeks to months, as the body reabsorbs the treated veins. A course of treatments may be recommended to work towards a good outcome. Results are not immediate and vary between individuals depending on the veins treated and personal factors.
It is normal for treated veins to look a little more noticeable at first, with some temporary bruising or discolouration, before they begin to fade. Smaller veins often respond sooner than larger ones. Because everyone’s veins and circulation differ, the number of sessions needed and the degree of improvement vary from person to person, and your doctor will give you a realistic idea of what to expect.Sclerotherapy treats the veins present at the time and does not stop new veins from appearing in future, as that depends on individual factors such as genetics and lifestyle. Some people choose to return for occasional maintenance treatment if new veins develop. There is no obligation to continue, and your doctor will talk you through what to expect over the longer term.Recovery and aftercare
Sclerotherapy is generally a low-downtime treatment, and most people return to their normal day soon afterwards. Good aftercare supports the result, and your doctor will give you personalised instructions. Common guidance includes:- Wear the compression stockings or bandages provided for the period your doctor recommends
- Walk regularly and keep moving, as gentle activity supports healthy circulation
- Avoid strenuous exercise, heavy gym sessions and hot baths for the first day or two
- Avoid prolonged standing or sitting still where you can
- Avoid direct sun and use a high-SPF sunscreen on the treated area while it settles
- Expect some temporary bruising or discolouration, which usually settles over time
What are the risks and side effects?
Sclerotherapy is a widely used treatment and is generally well tolerated, but like any medical procedure it carries potential risks. Being clear about these is part of responsible care, and your doctor will discuss them fully with you at your consultation.Common, temporary effects can include:- Bruising, redness or small raised areas at the injection sites
- Temporary discolouration or brownish lines along the treated veins, which usually fade over time
- Mild stinging, cramping or tenderness during or shortly after treatment
How much does sclerotherapy cost in North Sydney?
There is no single price, because the cost depends on how many veins are treated and how many sessions are needed. The most accurate figure is the one you receive at your consultation, once a doctor has assessed your legs and confirmed what is suitable. The main factors are:- The number and type of veins treated: a small cluster differs from more extensive treatment
- The number of sessions required: some veins need a course of treatments rather than one
- The practitioner: having your treatment assessed and performed by a qualified medical doctor is part of what you are paying for
