The situation

After pregnancy and breastfeeding many women notice that the upper breast has emptied and the skin envelope has loosened. The situation is a change in volume and shape rather than a disease, so people compare options that restore fullness: implants, autologous fat grafting, or accepting the change. Questions typically concern how much volume fat can add, how many sessions are needed, whether the result lasts, and whether future breastfeeding or screening is affected.

Common concerns: natural look · not wanting implants · future breastfeeding · screening anxiety

How much of the graft remains

Pooled volume retention

Retention by fat preparation method

Number of sessions

Sessions
More than one session may be needed because part of the graft is resorbed[1]organizationFat Transfer Breast AugmentationAmerican Society of Plastic Surgeons

Effect on breast imaging

Oncologic safety evidence

How to verify an institution

Instead of a ranking, use the public records that exist for this kind of procedure in Korea.

  1. Check the Ministry of Health and Welfare list of designated advanced regenerative medicine institutions for the designation number.
  2. Check the cell-processing facility permit register (K-ARM) when cells are isolated or processed.
  3. Treat case counts, success rates and "first" claims published by the institution itself as official claims until an independent record confirms them.
