Cosmax, South Korea's biggest cosmetics ODM (original design manufacturer) company, has launched an AI-driven personalised beauty business in Japan, marking a decisive shift away from contract manufacturing towards a technology-led model. The move is widely seen as a twin-pronged strategy: upgrading the sophistication of the K-beauty industry while simultaneously cracking one of Asia's most demanding consumer markets.
Personalisation becomes the new industry standard
The global personalised cosmetics market is expanding rapidly. According to Grand View Research, the sector was worth roughly $37.3 billion in 2023 and is forecast to grow at more than 8% annually through to 2030. As consumers increasingly favour products tailored to their specific skin condition, genetic profile and lifestyle over off-the-shelf alternatives, AI and big-data technologies are becoming the core infrastructure of the beauty industry.
Cosmax's approach involves analysing skin-diagnostic data through proprietary AI algorithms to determine the optimal combination of ingredients and formulations for each individual consumer. The company's competitive edge lies in coupling a self-developed skin-analysis platform with an AI model trained on tens of thousands of skin-data records to generate bespoke prescriptions.
Why Japan?
Japan has been chosen as the first overseas beachhead for Cosmax's AI personalisation push, and the logic is compelling. Japan is the world's third-largest cosmetics market, with annual sales of approximately ¥2 trillion (around 18 trillion Korean won), according to the Japan Cosmetic Industry Association (JCIA). Japanese consumers are renowned for exacting quality standards — captured in the concept of *monozukuri*, or artisanal craftsmanship — and have highly differentiated skincare demands, making the latent appetite for customised products considerable.
Japan's ageing population adds a structural tailwind: demand for functional personalised products addressing skin ageing and sensitivity is rising steadily. Cosmax also already operates a local subsidiary there, giving it established distribution channels and partnership networks that lower barriers to entry.
What the shift means for an ODM giant
Cosmax built its business by manufacturing products on behalf of major cosmetics houses, including Amorepacific and LG H&H (both South Korean conglomerates with large beauty divisions), as well as global brands. The AI personalisation venture represents something more ambitious: an attempt to move up the value chain into consumer-data analysis, formulation design and platform operations — well beyond the role of a contract manufacturer.
Industry analysts believe this strategic pivot could fundamentally alter the economics of ODM businesses. Personalised cosmetics command higher margins than mass-produced goods and generate strong customer lock-in effects. "If an ODM company internalises AI and data capabilities, it can transcend the limitations of pure manufacturing and achieve a profit structure closer to that of a platform business," one analyst at the Korea Cosmetic Industry Institute has noted.
Competition and challenges
The Japanese personalised beauty market is already fiercely contested. Local incumbents Kao and Shiseido have staked out early positions with their own AI skin-diagnostic technologies, while global players — including L'Oréal's Lancôme Le Teint Particulier and the American start-up Prose — are aggressively rolling out personalisation offerings.
Experts caution that winning the trust of Japanese consumers, who are notoriously sceptical of foreign brands, will hinge on three factors: the accuracy of AI-generated prescriptions, transparent communication about ingredient safety, and a user experience designed specifically for the local market. Regulatory risk is also a consideration: Cosmax must comply strictly with Japan's revised Act on the Protection of Personal Information, which came into full effect in 2022, governing the collection and use of personal skin data.
Lessons from abroad
Overseas precedents offer a mixed picture. The American start-up Function of Beauty achieved a valuation of over $1 billion with an AI-driven subscription model for personalised haircare and skincare, but subsequently struggled to sustain profitability and was forced to restructure. L'Oréal, by contrast, demonstrated clear technology leadership at CES 2021 with its Perso device, which combined AI skin analysis with on-the-spot product formulation.
These cases illustrate that technology alone is insufficient. Consumer education, price accessibility and the design of a sustainable subscription model are equally decisive in determining whether such ventures succeed or fail.
A turning point for K-beauty
Cosmax's move carries significance well beyond a single company's expansion plans. It represents a symbolic inflection point for the K-beauty industry as a whole — a shift from a manufacturing-centred OEM/ODM model towards a technology- and data-driven platform model. South Korea's Ministry of Trade, Industry and Energy and its Ministry of Food and Drug Safety formalised a regulatory framework for personalised cosmetics in 2020, providing institutional backing for companies entering this space.
Should Cosmax demonstrate tangible results in Japan, the industry expects the pace of expansion into South-East Asia and North America to accelerate. The company's AI personalisation business has only just begun, but its outcome will serve as a critical test of where K-beauty's competitive strengths can take it next.
