"Hada Labo" is a skincare brand launched by the pharmaceutical company Rohto Pharmaceutical in 2004. Its core philosophy is "Perfect Simple®" — the idea of "packing only what is essential for the skin and excluding unnecessary ingredients." The simple formula, free of fragrance, colorants, alcohol, and parabens, breaks free from cosmetic conventions and is made possible by Rohto's pharmaceutical manufacturing expertise. Additionally, the use of pharmaceutical-grade purified water in production and attention to quality even in unseen areas supports long-standing trust.
The "Hakuju" series was launched in 2005 and has been loved across generations for over 20 years as a whitening care line. In the full renewal in spring 2024, in addition to the traditional "moisturizing + whitening," allantoin, an ingredient to prevent acne and rough skin, has been added. The new formula, completed after more than 300 prototypes to achieve the "smooth and plump skin" admired by today's younger generation, delivers a feeling of skin improvement with every use.
