L'Oréal Groupe announces the expansion of 'Melasyl™', its exclusive molecular innovation, into 7 L'Oréal Paris and La Roche-Posay skincare products

With Melasyl™'s unique ability to intercept pigment precursors before they surface as dark spots and dullness, L'Oréal is expanding its offerings to deliver tailored care for all skin types, focusing on restoring a beautifully even and luminous complexion.

Patrick Girod, Managing Director of L'Oréal Thailand, Myanmar, Laos, and Cambodia, stated, “Scientific excellence is the foundation of L'Oréal's research and innovation. We believe that science and technology are the driving force for positive change, and we have dedicated decades to continuous research to develop effective products for consumers worldwide, including in Thailand. We recognize that pigmentation and dark spots are a major concern for Thai consumers, affecting not only skin health but also personal confidence. Incorporating the innovative Melasyl™ molecule into L'Oréal Paris and La Roche-Posay products reflects our commitment to developing safe, effective, cutting-edge, and accessible scientific innovations to meet the diverse needs of consumers.”

Melasyl™ is the result of nearly 20 years of research and development, involving the testing of over 100,000 molecules. Unlike traditional pigmentation treatments that focus on fading existing dark spots or inhibiting melanin-producing enzymes, Melasyl™ works differently as a 'Melanin Precursor Interceptor,' inhibiting melanin precursors by trapping them before they transform into the pigments that cause dark spots and dullness on the skin.

Dr. Tarun Chopra, Head of Science Communications for L'Oréal in South Asia Pacific, the Middle East, and North Africa (SAPMENA), stated, “Our scientific approach is based on the skin’s natural biological mechanisms. While melanin plays a crucial role in protecting the skin and determining its diverse skin tones, external factors such as high levels of UV radiation and pollution in Thailand can stimulate excessive melanin production, leading to dark spots and dullness.”

“Melasyl™ has revolutionized the treatment of these localized pigmentation issues by working at the source through an innovative mechanism. It blocks melanin precursors before they can be converted into the skin's natural pigmentation, resulting in significantly more effective results compared to conventional treatments, without disrupting the skin's natural pigmentation process,” added Dr. Tarun Chopra.

L'Oréal Paris: Beyond the core molecules, the 'product formula' is the heart of what makes this innovation truly effective. Dr. Richard Betts, L'Oréal Paris's Scientific Director for the SAPMENA region, revealed that the brand utilizes the 'Professional Power Couple' concept, combining Melasyl™ with glycolic acid and niacinamide to comprehensively address pigmentation issues at every stage, from exfoliation and radiance restoration to inhibiting melanin production. This synergy reduces dark spots by up to 88%, reflecting the application of advanced cosmetic science to daily skincare for masstige consumers at an accessible price.

La Roche-Posay, the #1 skincare brand recommended by dermatologists worldwide, elevates skincare innovation with a comprehensive protocol centered around Melasyl™ to effectively combat sun spots and dark spots. It begins with Mela B3 Facial Serum, an exclusive serum clinically tested and comparable to 4% hydroquinone in effectiveness and gentleness compared to standard pigment-reducing agents. The protocol also includes sun protection with Anthelios UVMune 400+ Anti-Dark Spots Fluid, infused with the exclusive Mexoryl 400™ sunscreen filter to shield against Ultra-Long UVA and High-Energy Visible Light (HEVL), key factors in dark spot formation, while effectively restoring and protecting skin like a tinted product.

These two skincare steps have demonstrated tangible results in Thailand through the personalized Skin Transformation program, designed under the care of dermatologists to address the specific needs of Thai people. This not only helps solve sunspots and dark spots but also boosts confidence and improves the quality of life for those facing these problems. This reflects La Roche-Posay's role as a brand committed to creating life-changing skincare results. Building on this success, in May 2026, the brand launched Mela B3 Dual Body Treatment, the first body care product containing Melasyl™, offering an exceptionally lightweight texture to effectively restore skin radiance, even in sensitive areas, in the Thai beauty market.

L'Oréal Thailand now offers Thai consumers access to a range of high-performance products featuring L'Oréal's exclusive Melasyl™ molecule, through seven products from two world-class beauty brands, La Roche-Posay and L'Oréal Paris. These products are designed to specifically address the needs of consumers in treating sun spots and dark spots.

• La Roche-Posay's Mela B3 product line includes Mela B3 Serum, Mela B3 Cream SPF 30, Mela B3 Micro-Peeling Gel, and Anthelios UVMUNE 400 Anti-Dark Spots Fluid, complemented by Mela B3 Dual Body Treatment, the brand's first body care product incorporating the innovative Melasyl™ molecule for comprehensive and effective care and correction of pigmentation issues across the entire body.
• L'Oréal Paris' Glycolic-Bright product line includes items such as the reformulated Glycolic-Bright Anti-Dark Spot Brightening Serum and the latest Glycolic-Bright Matte Luminizing Cream, developed to help reveal brighter-looking skin every day while effectively controlling facial oil.

Furthermore, by 2026, L'Oréal Thailand plans to launch additional new product formulas featuring L'Oréal's exclusive Melasyl™ molecule, continuing its commitment to delivering the best skin health and pigmentation solutions to Thai consumers.
