Dr. Rishabh Kala, lead scientist for Estée Lauder, and Dr. Jaime Emmetsberger, lead scientist for La Mer’s Max Huber Research Labs, were selected to deliver talks the 2026 IMCAS World Congress.

Held Paris in late January, the conference drew more than 20,000 participants.

In his presentation, “Skin Longevity: The Proven Role of Sirtuins and Mitochondrial Health in Dermatological Aging,” Dr. Kala highlighted Estée Lauder’s more than 17 years of research in skin longevity. He detailed the interconnected roles of sirtuins and mitochondrial dynamics in maintaining youthful skin function and discussed emerging research on sirtuin activators and mitochondrial-targeted technologies that are influencing the next generation of longevity-focused skin care.

Estée Lauder’s proprietary research demonstrates the ability of exclusive ingredients to counteract the effects of age-related declines in SIRT activity. By supporting visible age reversal and improved skin resilience, the company is continuing to advance skin longevity, helping skin cells perform at their peak and act younger and healthier for longer.

In her presentation, “Realizing Exosome Potential in Cosmeceuticals: Alternative Sources, Biological Benefits, and Challenges,” Dr. Emmetsberger highlighted exosomes as one of the most rapidly emerging areas of interest in cosmetic science. Rather than treating exosomes as a single “ingredient,” she framed them as biological messengers whose impact depends on an understanding of the vesicles themselves and the signals they carry.

As interest in this field continues to accelerate, Dr. Emmetsberger noted that the term “exosome” is often applied too broadly, leading to confusion and suggested clearer standards to address this. She also highlighted a growing shift toward more scalable options from plants, algae, and the microbiome, which are increasingly relevant for cosmetic applications. Building on Dr. Emmetsberger’s expertise, the company is continuing to deepen its scientific understanding of signaling vesicle platforms, like exosomes, and translating into delivering meaningful skin benefits.

According to Claude Saliou, SVP science, The Estée Lauder Companies, the research underscores the company’s leadership in skin longevity and regenerative aesthetics.
