Hada Labo Premium®
Medicated penetrating whitening lotion
Moist type
Directly approaches melanocytes, the source of spots.
Serum-grade moist whitening lotion with double active ingredients × two types of hyaluronic acid.
Product overview
Hada Labo Premium® Medicated Penetrating Whitening Lotion (moist type) is the top whitening line of Rohto Pharmaceutical's "Hada Labo®" brand. Designed for those who want to pursue both moisture and whiteness simultaneously with a rich, serum-like formula.
Compared to the regular Hada Labo series, the biggest feature is the double formulation of active ingredients. Whitening active ingredient White Tranexamic Acid® (Tranexamic Acid) suppresses the production of inflammatory substances in the early stage of spot formation, and the additional anti-inflammatory active ingredient Glycyrrhizic Acid 2K supports the prevention of rough skin and acne.
Contains two moisturizing ingredients: Nano Hyaluronic Acid (Hydrolyzed Hyaluronic Acid) and Hyaluronic Acid Na-2. Combined with skin conditioning and moisturizing ingredients Vitamin C derivative and Vitamin E, it penetrates deep into the stratum corneum damaged by UV rays and directly approaches melanocytes, the source of spots. Formulated to be weakly acidic, fragrance-free, colorant-free, mineral oil-free, alcohol (ethanol)-free, and paraben-free.

Double active ingredients to block spots and rough skin
Whitening active ingredient White Tranexamic Acid® suppresses the production of inflammatory substances that cause spots from the initial stage. Anti-inflammatory active ingredient Glycyrrhizic Acid 2K further prevents rough skin and acne, creating a clear skin base with double active ingredients. This is the biggest differentiating point from the regular Hada Labo version.
Direct approach to melanocytes
Penetrates deep into the stratum corneum of skin damaged by UV rays and directly acts on pigment cells (melanocytes) that cause spots. As the name "penetrating whitening" suggests, it features a deep approach beyond surface care.
Moist rich formula with two types of hyaluronic acid
Nano Hyaluronic Acid, which is micronized to about 1/100 the particle size of regular hyaluronic acid, penetrates deep into the stratum corneum, and Hyaluronic Acid Na-2, which holds 6L of water per gram, broadly maintains moisture on the skin surface. The moist, rich texture delivers satisfying hydration even for those concerned about dryness.
Skin conditioning and moisturizing ingredients that refine skin texture
Vitamin C Phosphate Mg (Vitamin C derivative) conditions the skin from inside the stratum corneum, and Vitamin E conditions it from the outside, preventing dryness caused by UV damage. It replenishes moisture and firmness, leading to smooth skin with refined texture.

Brand Story
Restore your natural translucency. The philosophy of Hakuju Premium®
Rohto Pharmaceutical's "Hada Labo®" was born in 2004 under the philosophy of "Perfectly Simple." The concept of removing unnecessary elements and delivering only the essential ingredients to the skin at the highest purity is proven by its achievement of 14 consecutive years as Japan's No.1 in domestic sales volume in the skincare cosmetics category (Intage SRI/SRI+ data).
The vision of Hakuju Premium® is "to aim for the natural translucent skin you inherently have." For example, the uniform skin tone and translucency of skin that has not been damaged by UV rays, like the inside of the upper arm which is less exposed to sunlight—that is the natural skin Rohto Pharmaceutical aims for. Rohto's unique research has revealed that visible spots increase at a rate 2.3 times faster after age 35, making early intervention on melanocytes important. Hakuju Premium® condenses this scientific knowledge into its products.
Also, Hada Labo® places great importance on environmental responsibility and has continued sustainable product development since launching refill packs in 2005, including adopting biomass containers made from plant-derived materials.
