🌱 Brand Story
Hada Labo was born in 2004 from the desire of young employees at Rohto Pharmaceutical to deliver skincare focused on ingredients at an affordable price. Leveraging years of research on hyaluronic acid developed for eye drops and stomach medicine, it was developed with the philosophy of "only what the skin needs, only the necessary amount, no unnecessary ingredients" — a "perfectly simple" approach. It was commercialized in an unprecedented six months and has since grown into a brand that has maintained the top sales in the skincare category in Japan for many years.
The "Hada Labo Shirojun" series is the brightening line of Hada Labo. It inherits the moisturizing philosophy of the Gokujyun series, which focuses on hydration, with the concept of "moisturizing while achieving clear skin." The current Shirojun Quasi-drug brightening emulsion, renewed in spring 2024, has evolved to include tranexamic acid as a brightening active ingredient and allantoin as a new skin roughness prevention ingredient, allowing it to address more skin concerns simultaneously. With pharmaceutical-quality control and cost performance that allows generous use, it makes brightening care a part of your daily routine.
