- Reticular Veins and Spider Veins
What are Reticular Veins?
Reticular veins are smaller types of veins. These veins are usually about 2–3 mm in diameter and often do not protrude on the skin surface. They are a closely grouped network of small veins. They are usually blue to greenish in colour and frequently feed areas of spider veins that are closer to the surface. Reticular veins are predominantly located on the inner parts of the thighs, backs of the legs, and ankles. They can also be associated with symptoms of pain and discomfort in the legs.
Reticular veins do not normally exist for no reason. Sometimes (though not always), there is underlying venous insufficiency which cause them to occur.
What are Spider Veins?
Spider veins are also part of varicose veins. They are smaller veins (<1mm in diameter), and they are closer to the surface of the skin than reticular and varicose veins. They can be blue, purple or red in colour, are frequently extensive, and may appear in linear, starburst or tree-like pattern distributions

Spider Veins Treatment
Microsclerotherapy
Microsclerotherapy is a non-surgical treatment option for spider veins and reticular veins, typically performed as a clinic procedure.
How it works:
- A liquid sclerosant (at a lower concentration) is injected directly into the spider veins using a very fine needle and a special visualization system.
- The sclerosant destroys the lining of the vein, causing the vein walls to stick together.
- Blood stops flowing through the treated vein, which then scars down and is absorbed by the body.
Aftercare:
- Compression stockings must be worn for 2–4 weeks after treatment.
- Normal activities can be resumed immediately.
- Multiple sessions may be required to remove all visible veins.
Possible side effects:
- Bruising
- Itching
- Brown discolouration / hyperpigmentation
- Redness at injection sites
Rare complications:
- Skin ulceration
- Allergic reaction to the sclerosant
Important to note:
- Once treated, spider veins will not reopen.
- However, microsclerotherapy does not prevent new spider veins from developing.
