Reconstructed human skin: scientific advances for our industry and beyond

“Creating the beauty that moves the world” means sharing our scientific breakthroughs within our industry and other sectors to make them accessible to researchers worldwide. Our expertise in reconstructed skin is a prime example.

Since 1989, we have been at the forefront of developing reconstructed skin models for a world without animal testing. This year, we introduced Skin Technology by L’Oréal, a new platform that combines the best of biology, mechanics, and electronics to pioneer a new generation of inclusive, bioprinted skin models. These models replicate the complexity of human skin and its biological processes, from tanning to scarring. By setting new testing standards, we are accelerating research towards more responsible beauty while extending our expertise to healthcare providers, startups, and research institutions.

One example is our partnership with Bakar Labs, the biotech incubator at the University of Berkeley (USA). This collaboration gives medical research startups free access to our reconstructed skin models. L’Oréal also channels its fundamental research into public health by working with renowned institutions like Percy Hospital (France) and the University of Oregon (USA). Our partnership with the University of Oregon, for instance, has led to the development of an advanced biomimetic artificial skin model, leveraging rapid 3D bioprinting technology to fast-track research into treatments for severe skin conditions.

Green sciences: advancing beauty through sustainability and performance

By combining the expertise of our researchers with an extensive ecosystem of global partnerships – including startups, research institutes and suppliers – we create high-value added ingredients drawing on nature and science.

Our Green Sciences incubator is exploring the potential of living organisms to provide sustainable ingredients with startup Interstellar Lab. This Franco-American company is revolutionising sustainable agriculture with AI-driven autonomous greenhouses. This technology has the potential to optimise and accelerate the production of plant-based bioactives, even in harsh environments, ensuring a reliable supply of high-quality ingredients.

We are continuing our collaboration with Microphyt, a French company pioneering low-carbon fermentation technology for microalgae production. L’Oréal has already selected five microalgae-derived ingredients for future industrial-scale applications.

Danish probiotic and microbiome specialist Lactobio joined L’Oréal’s research network following its acquisition in 2023, strengthening our 20 years of expertise in microbiome science. Together, we are developing new probiotic and postbiotic formulations harnessing the targeted power of bacteria for innovative cosmetic solutions.

Finally, we continue to invest in the creation of unique fragrances, taking inspiration from nature in our search for unique scents. Our exclusive partnership with Cosmo International Fragrances grants us access to Osmobloom, a waterless, low-energy extraction technology that captures the true olfactory essence of flowers. This process opens up new creative possibilities for our perfumers. The first fragrance to feature Osmobloom, a tuberose extract, is Private Talk by Valentino Beauty.

Melasyl™: a revolutionary molecule for skin pigmentation issues

L’Oréal is committed to making beauty more inclusive and accessible. With the launch of Melasyl™, its exclusive and proprietary molecule, L’Oréal’s revolutionary science aims to combat localised pigmentation issues that cause dark spots and acne scars. The result of 18 years of research, Melasyl™ captures melanin precursors before they transform into coloured pigments. Validated by over 121 scientific studies, Melasyl™ has proven its effectiveness in correcting localised pigmentation, regardless of skin colour.

Drawing on its dermatological expertise, La Roche-Posay has incorporated Melasyl™ into its Mela B3 range, now available in nearly 40 countries. The combination of the Mela B3 serum and an SPF30 cream offers an inclusive preventive routine to correct dark spots while protecting skin from UV exposure, an aggravating factor in hyperpigmentation.

As part of a commitment to “beauty for each”, L’Oréal Paris also launched Glycolic Bright in 2024. This new range harnesses the power of Melasyl™ alongside glycolic acid and niacinamide to enhance skin radiance. Deployed first in emerging markets, it embodies L’Oréal Paris’ dedication to effective and accessible beauty.

Hair: innovating for beauty experiences adapted to every curl

By 2030, an estimated 40% of the global population will have curly, coily or wavy hair. L’Oréal is committed to developing inclusive haircare solutions tailored to all hair types and needs.

A study of 2,500 people in 22 countries led to the creation of a new classification system, categorising curls into eight types. For some curls, it highlights the need for enhanced hydration, specific care routines such as weekly washing or the need for multiple daily treatments.

For the first time, our researchers have created a 3D visualisation of curly hair, mapping the intricate interweaving of hair fibres. This scientific and technological expertise has led to the development of innovative solutions that effectively address the unique needs of curly hair.

In 2024, Redken launched Acidic Bonding Curls, the first silicone- and sulphate -free bonding treatment for curly hair. Powered by its patented D.E.S CURLS technology, this unique formula repairs, hydrates and strengthens fragile curls. The global rollout of this range is underway, ensuring more consumers can access this game-changing routine.
