Hada Labo

Hada Labo (肌ラボ, "Skin Lab") is a Japanese skincare brand launched in 2004 by Rohto Pharmaceutical, a company founded in 1899 in Osaka [5]. Built around hyaluronic acid and a stated philosophy of "everything your skin needs, and nothing it doesn't," the brand became a fixture of Japanese drugstores and, later, an internationally discussed name in the online skincare community.

Its reputation rests largely on a single product. The Super Hyaluronic Acid Moisturizing Lotion — sold in Japan as Gokujyun — was, according to the company, the number one lotion in Japan for seven consecutive years [5], and it gathered a following abroad through word of mouth rather than advertising. The brand remains active across multiple regions, with current product lines and editorial coverage as recent as 2025.

Hada Labo was developed by Rohto Pharmaceutical, a Japanese company that the brand traces to an 1899 founding in Osaka. The name translates from Japanese as "Skin Lab." From the start, the brand positioned itself around a pared-down approach to skincare, seeking, in its own description, to remove "unnecessary additives, colorant, fragrance and mineral oil." The individual founders of the Hada Labo line are not recorded in the available sources.

Hada Labo is owned by its creator, Rohto Pharmaceutical. The brand's about-page identifies Rohto as a company founded in Osaka, and on that basis places its corporate home in Osaka [2]; Wikipedia, by contrast, lists the headquarters as Tokyo [5]. The brand's US-facing identity is marketed as "Hada Labo Tokyo," which appears to be the source of the discrepancy — "Tokyo" functions as a marketing reference in the brand name rather than a corporate address. For the American market, the line is produced by Mentholatum, a Rohto subsidiary, under separate branding and formulation [5].

Hada Labo's range centers on hydration, spanning cleansers, hydrators, gel creams and eye creams, with the brand's about-page citing a portfolio of more than 60 products. The signature ingredient is Super Hyaluronic Acid, a trademarked formulation the company describes as a proprietary blend of hyaluronic acid types developed to hold moisture at different depths of the skin.

The number of hyaluronic acid types varies by product line, and sources differ accordingly. The brand's US science page describes Super Hyaluronic Acid as a blend of three types [3], while Hello Magazine reports that the Premium Lotion uses seven types "working at different skin depths" [8] — a reflection of distinct formulations rather than a contradiction. Refinery29 identified the three acids in the original Goku-jyun lotion as hydrolyzed hyaluronic acid, sodium acetylated hyaluronate and sodium hyaluronate. Across its marketing, the brand repeats the often-cited claim that hyaluronic acid can hold up to 1,000 times its weight in water.

Beyond the flagship lotion, the brand highlights a Skin Plumping Gel Cream, which combines serum and moisturizer, and a Replenishing Hydrator essence that the company says is Japan's top-selling product, with "one sold every 2 seconds." In Japan the range is organized into recognized lines including Gokujyun for intense hydration, Shirojyun for brightening, and Gokujyun Alpha for anti-aging. The brand's products are formulated without parabens, dyes, mineral oils or added fragrance.

Hada Labo summarizes its approach with the phrase "Perfect and Simple," blending, in the company's words, "advanced technologies with the Japanese value of simplicity." Its philosophy pages extend this to J-beauty traditions of application, emphasizing manual techniques — patting product into the skin, palm-pressing for warmth — over elaborate routines, on the principle that "even the best products aren't as effective if your skin isn't healthy." The brand sits at a drugstore price point, the original lotion costing roughly $12 a bottle.

Hada Labo's cult standing developed mostly online. Marie Claire wrote in 2017 of the Gokujun lotion's internet fame, citing some 600 five-star Amazon reviews and a steady presence on skincare forums [7]. The following year, Refinery29 described the Goku-jyun lotion as having "received rave reviews across the board, from all over the world," driven by "word-of-mouth cred on Amazon, Reddit, and other communities," and noted that Reddit's r/AsianBeauty community treated it as a "Holy Grail" product for dewy skin [6]. The brand has been linked to the J-beauty, glass-skin and skin-minimalism trends of the 2010s. Its Skin Plumping Gel Cream was named "Most Effective Skin Plumper" by New Beauty Magazine in 2017 [2].

A recurring caveat in this coverage is that the US "Hada Labo Tokyo" line differs from the Japanese originals; Refinery29 observed that between the two versions "the formulas are hardly comparable" [6].

The brand's packaging history is documented through two changes. In 2005 it switched from glass to plastic bottles and introduced refillable pouch variations. In November 2019 it revised the packaging of its Gokujyun and Shirojyun lines using what Wikipedia describes as "plant-derived materials" [5].

Hada Labo is an active brand operating across multiple regions. It launched in several Asian markets before expanding to the United States, where in 2015 Hada Labo Tokyo became, per Wikipedia, the first Japanese cosmetics brand to launch at US mass retailers, debuting at 235 Harmon locations [5]. According to its about-page, parent company Rohto Pharmaceutical operates in 12 major markets and distributes in more than 150 countries [2]. The most recent visible activity in the sources is a September 2025 editor review of the brand's Premium line in Hello Magazine, which referred to it as "Japan's number one selling skincare brand for many years" [8].
