Sclerotherapy for thread veins on the legs

Sclerotherapy

Reduce visible thread veins on the legs

About the treatment

Visible thread veins and small superficial blood vessels on the legs are very common. They can develop as a result of genetics, age, hormonal changes, pregnancy and other factors.

Sclerotherapy works by injecting a solution directly into the visible blood vessels. The solution causes the vessel wall to react, after which the blood vessel closes and is gradually absorbed by the body. The blood is then naturally redirected through other, healthy blood vessels.

The treatment is particularly well suited to smaller superficial veins and thread veins on the legs. The result develops gradually, and several treatments may be needed depending on the number and size of the vessels treated.

Sclerotherapy is a targeted treatment where the aim is to reduce the visibility of the unwanted blood vessels and create a more even appearance on the legs.

The process

What to expect at Caolín

The surgeons at Caolín
  1. Consultation

    We begin by assessing your legs and the visible blood vessels. Among other things, we look at the size, location and appearance of the blood vessels to determine whether sclerotherapy is the right treatment.

  2. The treatment

    The specially developed solution is carefully injected directly into the selected blood vessels. The treatment is carried out precisely and in a targeted way.

  3. After the treatment

    There may be mild redness, swelling or bruising in the area. You will receive advice on aftercare and any precautions, so your skin and the treated vessels have the best conditions to heal.

  4. The result

    The treated blood vessels close and are gradually broken down by the body. The improvement therefore becomes more visible over time. If visible vessels remain, a further treatment can be considered.
