If you are short on time, here is the honest version. In Korea, melasma is usually treated with a combination of low-energy laser toning (Q-switched or picosecond Nd:YAG), oral tranexamic acid, and prescription brightening creams. No single visit clears it. Most people run a course of treatments over two to three months, then keep it in check with maintenance.
Rough 2026 price band: a single laser toning session runs about 50,000-150,000 KRW (roughly $37-$110), and clinics usually sell 5-10 session packages for 300,000-1,200,000 KRW (about $220-$880). A month of oral tranexamic acid is cheap, often 20,000-50,000 KRW ($15-$37). Gangnam clinics sit at the top of these ranges.
The most important thing to know: melasma responds slowly and relapses easily. A clinic promising to erase it in one session is either overselling or about to use settings that can darken your skin. Slow and conservative wins here.
