Recommended recovery time and post-op care in Seoul is two weeks. Sometimes, 10 days is sufficient.

Skin suture removal is usually not needed, because Dr Kim uses absorbable suture material.

The final result takes time to be apparent. Residual swelling around the lower portion of breast below the nipple is normal.

Pre-op testing to officially document you are strong and healthy and it is safe for you to have surgery is NOT included in the surgical fee.

You will need to get those blood tests done at the clinic 48 hours before surgery. They cost US$200.


The standard pre-operative tests include:

  1. Internist Exam [internal medicine specialist, ECG, and ultrasound heart exam]
  2. Blood Analysis (including for HIV, all types of hepatitis and any other infectious blood diseases)
  3. Urine Analysis (urine test, urinalysis)
  4. Blood Group (blood typing)
  5. PT (Prothrombin Time | Clotting Time)
  6. PTT (Partial Thromboplastin Time)

Adult blood tests need to include HIV, Hepatitis B & Hepatitis C.

Those do not disqualify a patient from surgery in Korea but there are strict protocols about where (at the National Medical Center, not at the clinic) surgery can be performed for patients requiring special care for infectious diseases.

After post-op discharge from the clinic, you will need to come back to the clinic every day, especially the first three days. After that, you can come to the clinic on alternate days if you prefer.

Dr Kim explains:

The residual swelling underneath of the peri-areolar area usually takes time before flattening, because the swelling is caused by hardening of residual fatty tissues.

If I removed all of the fatty tissue during surgery, the nipple area would shrink.

The swelling takes more than three months to disappear.
