Demand for GLP-1 obesity treatments like Wegovy and Mounjaro has exploded in Seoul, where aesthetic clinics heavily prescribe them. Yet, this has created a stark supply imbalance across South Korea.
GLP-1 Supply Heavily Concentrated in Greater Seoul
Ministry of Health and Welfare data from January 21 shows 914,000 units of Wegovy and Mounjaro supplied nationwide in November 2025. About 65.8%—or 601,000 units—went to Greater Seoul, including Incheon and Gyeonggi Province.
- Seoul alone: 34.5% of total supply
- Gyeonggi Province: 26%
- Incheon: 5.3%
Outside the capital, Busan received 5.9% and Daegu 4%, while most other regions got around 1% each.
Disparity Exceeds Population Distribution
Greater Seoul houses roughly 50% of South Korea's population but claims over 65% of GLP-1 drugs. This pattern stems from surging demand in urban aesthetic clinics.
