What happens after thread vein treatment?
If you’ve decided to treat thread veins with ThermaVein® for facial veins or sclerotherapy for leg veins, it’s natural to wonder what happens after the procedure. Understanding the aftercare process helps ensure the best results, minimises complications, and keeps recovery smooth. At The Thread Vein Clinic, our doctor-led team provides expert guidance to support you throughout your journey. Our clinics are conveniently located at Harley Street, Liverpool Street (London), and Tunbridge Wells (Kent), making follow-up care easy to access.
Aftercare following ThermaVein® treatment
ThermaVein® is a minimally invasive treatment that uses a fine probe to deliver a micro-current of heat, sealing facial thread veins instantly. Because it is precise and gentle, recovery is usually very quick.
What to expect:

- Immediate results: Many patients see veins disappear during the session.
- Mild redness: Slight redness or warmth may appear on the treated area but usually resolves within a few hours.
- No downtime: You can return to normal activities immediately, including work or social engagements.
- Avoid irritation: For the first 24–48 hours, avoid harsh facial scrubs, extreme heat, or heavy makeup on the treated area.
- SkinCeuticals PhytoCorrective Serum: We recommend SkinCeuticals Phyto Corrective Serum (£78) to soothe and hydrate the skin post-treatment, enhancing recovery.
Our doctors provide detailed instructions during your consultation, ensuring you know exactly how to care for your skin post-treatment.
Aftercare following sclerotherapy
Sclerotherapy involves injecting a safe medical solution (sclerosant) into leg veins, causing them to collapse and be reabsorbed by the body. While highly effective, following aftercare instructions is crucial for the best results.
Key aftercare steps include:
- Wear compression stockings: Typically worn for 1–2 weeks after treatment to support circulation and healing.
- Gentle activity: Walking and light movement are encouraged to improve blood flow. Avoid vigorous exercise for a few days.
- Avoid prolonged standing or sitting: This helps prevent swelling or discomfort.
- Monitor treated areas: Mild bruising or temporary redness is normal; any unusual symptoms should be reported to your doctor.
Patients often notice significant improvement within 2–6 weeks, depending on the area and number of veins treated. Additional sessions may be recommended for more extensive leg veins.
Why aftercare matters
Following aftercare instructions ensures that your treatment with ThermaVein® or sclerotherapy delivers the best possible results. Proper care:
- Reduces the risk of complications such as bruising or irritation.
- Supports quicker healing and vein absorption.
- Maximises the longevity and effectiveness of your treatment.
