Korean medicine treats melasma/blemishes addressing root cause: ① hormonal/blood-stasis melasma (Hyeolbu-jukeo-tang base), ② damp-heat blemishes (Yongdam-saganh-tang), ③ kidney-yin deficiency age spots (Yukmijiwhang-tang base). Combined with laser toning, pharmacopuncture, topical care. Effects: ① melasma: 60–70% improvement (3–6 months), ② sun spots: 70–80%, ③ post-inflammatory: 80–90%. Long-term constitution improvement prevents recurrence — often Korean medicine's biggest advantage over laser-only.
