To unveil our new Chronologiste Overnight Youth Serum, we began with an exceptional moment. For this global launch, we took over Los Angeles for an exclusive evening of Power Talks & Chronologiste Experience — a tribute to the science of longevity and the art of timeless hair. Take a glimpse into an iconic moment with Demi Moore, captured just before her powerful appearance. Where luxury, innovation, and modern beauty meet. #Kerastase #Chronologiste #DemiMoore #HairLongevity #HairCare
