Thread Vein Removal

Thread veins/Spider Naevi

Thread veins or broken capillaries commonly occur around or under the nose or on the cheeks and are often the underlying cause of redness on the cheeks. Spider Naevi are a cluster of broken vessels that can look like a red spot. They occur most frequently on the chest or cheeks and can be quickly and easily removed with thermocoagulation.

Are there any side effects?

Overall blemish removal is a safe and well tolerated treatment. It produces excellent cosmetic results and side effects are mild and temporary. However, as with all medical procedures, there are some potential risks which you need to be aware of listed below.

Potential side effects related to using a needle for the procedure include:

  • Temporary discomfort – brief – can be reduced with Emla cream
  • Redness at the site (maximum 20 – 40 minutes post procedure – can last up to 48 hours)
  • Bruising or scab formation (usually small and fades within 1 week)
  • Swelling (mild – can last up to 48 hours after treatment)
  • Infection (very rare)

Potential side effects related to Thermocoagulation (diathermy) include:

  • Incomplete removal – larger veins and extensive areas are likely to require further treatments. Allow a minimum time interval of 4 weeks between further treatment sessions
  • Recurrence – some veins may resolve initially and then gradually reoccur and require further treatment. Allow up to 12 weeks to see the full effect of treatment
  • Hyperpigmentation – rare
  • Blistering – rare
  • Dimple or pin size pit in the skin (most heal and resolve over a few weeks)
  • Scarring (rare) – best to under treat and return for a top up – rather than over treat in 1 session


If there are lots of thread veins on the legs or face it may require 2 – 4 treatment sessions.
