Cosmetics and quasi-drugs categories
In Japan, the Japanese Ministry of Health, Labour & Welfare classifies the beauty products under 2 categories: cosmetics and quasi-drugs. Quasi-drugs, in opposite to cosmetics, are medicated, have a mild pharmacologic effect and include active ingredients. If the product is approved as a quasi-drug by the ministry, the manufacturer is allowed to actually claim the effectiveness of the product.
"COSME DECORTÉ" is Kose's prestige brand.
