Brand Story
Hada Labo® born from the philosophy of "Perfect Simple"
Hada Labo® was born in 2004 under Rohto Pharmaceutical Co., Ltd. with the concept of "Perfect Simple", which means "removing unnecessary ingredients and delivering only the essential ingredients to the skin in minimal amounts and highest purity." It is also known for its development story where young staff got hints from ingredient cosmetics at drugstores and commercialized the product in just six months. It gained explosive support immediately after launch and has grown into a national brand boasting 14 consecutive years as Japan's No.1 in domestic sales volume in the skincare cosmetics category (Intage SRI/SRI+ data).
The Hada Labo Shirojyun series is a Quasi-drug whitening line born from Hada Labo®. It centers on Rohto Pharmaceutical's unique White Tranexamic Acid® as the core ingredient, aiming to achieve both clarity and moisture simultaneously. The formula was renewed in spring 2024 to provide higher whitening effects and skin irritation prevention. As part of environmental efforts, since launching refill products in 2005, the series has continued sustainable product development, including the introduction of biomass containers (plant-derived).
