Here is a polished English translation of the Chinese title: **L’Oréal China and Huashan Hospital Jointly Launch First Results from Dermatology Research Collaboration — La Roche-Posay’s Supramolecular Oil-Control Balancing Lotion & Emulsion Debuts** Alternatively, a more concise version: **L’Oréal China & Huashan Hospital Unveil First Dermatology Research Results — La Roche-Posay Launches Supramolecular Oil-Control Balancing Skincare Set**

ShanghaiApril 28, 2026 /PRNewswire/ — On April 27, the “Grand Beauty, Smart Future” L’Oréal China 2025/2026 Annual Development Strategy Communication Meeting was successfully held, bringing together industry forces to explore the answers to beauty in our era. La Roche-Posay, a dermatological science skincare brand originating from France, proudly launched the first tangible product from the “Huashan Hospital X L’Oréal China Medical-Research Co-creation Dermatology Science Laboratory” — the Supramolecular Oil-Control Balancing Toner & Lotion^[1]. This series is the first to apply dual co-supramolecular technology, breaking the limitations of oil-control and acne-clearing products that may irritate the skin, offering a new skincare choice for oily skin that provides gentle oil control and root-cause acne suppression.

During the 8th China International Import Expo in November 2025, L’Oréal China entered into a strategic collaboration with Huashan Hospital affiliated with Fudan University (hereinafter referred to as “Huashan Hospital”), officially establishing the “Huashan Hospital X L’Oréal China Medical-Research Co-creation Dermatology Science Laboratory.” This laboratory deeply focuses on three core areas: scientific research, technology transfer, and science communication. Currently, the laboratory has taken the lead in completing its first listing at “Meichuang Jingjie” and innovatively adopts a “dual-listing” operational model, with plans to simultaneously establish a presence at Huashan Hospital’s East Campus in the future. This high-level scientific research platform aims to break down barriers between the industry and clinical sectors, accelerating the implementation of cutting-edge technologies while empowering the high-quality development of the beauty industry in Jing’an District.

Nobel Scientist Laboratory Empowers Supramolecular Technology, Medical-Research Co-creation Drives Product Transformation

In terms of product technology transformation, La Roche-Posay has deepened its strategic synergy with the Dermatology Department of Huashan Hospital to jointly explore the health management of acne-prone and oily skin. The research teams from both sides conducted joint studies on oily acne-prone skin issues. Using advanced bio-detection technologies, they deeply analyzed the scientific value of supramolecular salicylic acid in dermatological applications and successfully revealed that, under the dual verification of genomics and lipidomics perspectives, the core active ingredient combination containing supramolecular salicylic acid can significantly enhance the expression of five key barrier indicators, reshaping skin defense from the foundational logic. In terms of soothing/improving redness, it achieves multi-effect regulation from base repair to protein release, precisely inhibiting IL-6 and NF-κB signaling pathways, deeply improving skin issues caused by discomfort.

Simultaneously, by targeting and regulating upstream and downstream pathway signals that promote lipid synthesis, it reduces lipid production and related protein expression in multiple dimensions. This breakthrough discovery has laid a solid scientific foundation for both parties to collaborate on innovation and optimization of products based on this ingredient, driving the launch of the “New Supramolecular Oil-Control Balancing Toner & Lotion” in April. This product achieves gentle oil control and reduces acne recurrence over 4 weeks, efficiently transforming “clinical wisdom” into “consumer products.”

This innovative breakthrough not only upgrades the product from the source of formula design but also provides solid support in efficacy verification, opening up new ideas for repairing oily acne-prone skin. It fully demonstrates La Roche-Posay’s leading R&D strength in dermatological science as the No.1 recommended skincare brand by dermatologists globally^[2].

Facing the Challenge of Skin “Out of Control,” Leading New Trends in Scientific Skincare

Based on continuous insights into consumer needs, La Roche-Posay remains committed to deep research in dermatological science, dedicated to providing professional, safe, and effective solutions for various skin issues. Faced with the multiple pressures brought by high-paced lifestyles, the issue of young consumers’ skin being “out of control” is increasingly drawing attention. Phenomena such as excessive sebum production, recurring acne, and fluctuating skin conditions not only affect appearance but also drive consumers to have higher expectations for more scientific and systematic skincare solutions. At the same time, the selection criteria for oil-control and acne-clearing products are constantly evolving, with texture, ingredients, efficacy, and compatibility becoming key dimensions of consumer focus.

The new La Roche-Posay Supramolecular Oil-Control Balancing Toner & Lotion is specifically designed for Asian oily sensitive skin and oily acne-prone skin. It is formulated with 0% alcohol, 0% fragrance, and 0% colorants, and features the brand’s proprietary “Triple Acid” golden ratio formula of 9:8:5 (Polyhydroxy Acid^[6]: Sulfonic Acid^[7]: Supramolecular Salicylic Acid). This provides a tailored “Triple Acid Peel” solution for acne-prone users, targeting the root cause of acne while refining pores and reducing blackheads. Additionally, the co-supramolecular [Salicylic Acid + Niacinamide] gently reduces redness and fights acne, while the co-supramolecular [Salicylic Acid + Betaine] provides hydration without dryness. This dual synergy delivers long-lasting oil control and regulates the skin’s oil-water balance.

The La Roche-Posay Supramolecular Oil-Control Balancing Toner has a clear, lightweight texture that instantly absorbs excess oil, achieving oil control, acne reduction, and skin refinement within 4 weeks^[3]. The La Roche-Posay Supramolecular Oil-Control Balancing Lotion can reduce acne in 7 days^[4] and gently improve skin texture within 4 weeks^[5], reducing sebum production at the source. It features a light gel texture that is refreshing and non-sticky, like an invisible matte film. The product is also enriched with the star ingredient B5^[8], combined with Betaine and Hyaluronic Acid^[9], providing triple care to gently build tolerance, strengthen the skin barrier, soothe irritation, and hydrate. This offers more comprehensive protection for oily and sensitive skin, delivering a refreshing skincare experience for consumers.

Upholding the brand mission of “Dermatological Science, Changing Lives,” La Roche-Posay consistently delves into the skincare needs of different populations, building a product matrix of “Treat with Expertise, Care with Science, Indulge with Innovation,” and continuously exploring the infinite possibilities of scientific skincare. In the future, the brand will continue to drive product iteration through scientific innovation, providing professional, safe, and effective solutions for more skin issues, helping every consumer embrace healthy and confident beauty under professional care.
