FAQs on Thermocoagulation Is thermocoagulation safe? As with any medical treatment, there are certain risks and side effects but thermocoagulation is generally very safe. Reported and known risks associated with the treatment can include bruising or scarring. No major side effects have been reported. Are thermocoagulation and ThermaVein® the same thing? Yes. ThermaVein® is a brand name for the machines that are used to perform thermocoagulation. We use ThermaVein-branded machines, so you may see or hear “thermocoagulation” and “ThermaVein®” used interchangeably to describe the same thing. Is any preparation needed? You will need to attend with no face makeup, or be willing to remove it just before treatment. Does it hurt? For most patients, the sensation is similar to a warm pin prick, or possibly a small electric shock. Only the top layers of skin are breached; the vein itself is not pierced. How long does it take? We give patients a 45-minute slot, as consultation and treatment is performed in the same appointment. Is any aftercare needed? There is minimal aftercare needed following thermocoagulation, however there are a few things to make note of. For the first 48 hours, wash the area gently without scrubbing or rubbing, do not keep touching the treated area, avoid stretching the skin, avoid excessive exercise or any activities which might cause sweating or dilation of the capillaries and, if you are prone to flushing, avoid alcohol and spicy food. Please do not wear makeup for at least 24 hours after treatment and, if possible, leave it 48 hours. Apply aloe vera gel to soothe irritated skin. After healing, protect skin with a good broad-spectrum SPF and avoid sunbeds. Use tepid water on the face and moderate temperature on the body in baths and showers. Avoid harsh cleansing, steaming and exfoliation of the skin for the first week, as well as avoiding stretching and pulling the skin for the first week following treatment.
