Q. How is the 'Quasi-drug active (薬用化粧品有効成分)' tag determined?

Regulatory tags reflect each ingredient's status under Japan's PMD Act (薬機法) and Food Sanitation Act, plus relevant systems like Foods with Function Claims (FFC) and Tokuho. Tags are an editorial classification — buyers should always verify the latest regulatory status against MHLW and CAA primary sources before product launch.
