Mono Thread Treatment: What Happens, Aftercare and How Long Effects Last

The approach differs between providers. Always follow the instructions you receive. This page is part of our guide to mono threads.

Consultation

A qualified clinician should check your history, examine the area and explain risks, alternatives and limits. You should receive written consent information and time to decide.

Treatment

• The skin is cleaned and may be numbed with local anaesthetic or cream
• Many fine threads are inserted just under the skin using fine needles or cannulas
• The needle is withdrawn, leaving the thread in place
• A session often takes under an hour, depending on the area

Straight afterwards

Tiny puncture marks, redness, mild swelling and bruising are common. Some people feel small lumps or the threads under the skin.

Aftercare

Typical advice includes:

• Avoiding strenuous exercise and heat for a period
• Not rubbing or massaging the area
• Keeping the skin clean
• Sleeping on your back
• Avoiding tight underwire

Duration

PDO threads are absorbed over several months. Providers may suggest repeating treatment. Evidence on how long any skin benefit lasts is limited, and results vary.

Repeat treatments

Repeating adds cost and cumulative risk. Ask how many sessions are suggested and what you can expect at each stage.

Contact your clinician if

You develop fever, increasing pain, redness, discharge, firm lumps or thread coming through skin. See breast enlargement safety for urgent warning signs.
