This partnership integrates Yatsen's rigorous scientific infrastructure with the world's leading prestige beauty retailer, marking a significant milestone in Yatsen's continuing evolution into a global beauty technology powerhouse.

The collaboration will see Perfect Diary's premium, science-backed portfolio of products making its milestone debut across Sephora's extensive retail network of around 300 outlets, including Tier 1 hubs such as Beijing, Shanghai, Guangzhou, and Shenzhen. This expansion reflects a broader shift in the Chinese beauty market, where sophisticated consumers increasingly prioritize proven efficacy and technological excellence.

Since 2020, Yatsen has invested approximately $100 million (RMB 700 million) in R&D, establishing a robust global innovation ecosystem anchored by advanced research centers in China and Europe.

This commitment to scientific innovation by Yatsen Group is epitomized by the core product lineups driving Perfect Diary's entry into Sephora. As breakthrough products blending biotechnology with beauty, the Perfect Diary Biolip Essence Lipstick 3.0 and Biolip Essence Matte Lipstick 3.0 utilize exclusive patented technology to mimic the skin's biological composition.This creates a functional film on the skin's surface that enhances makeup longevity and reinforces the protective barrier, achieving a seamless fusion of high-performance color and clinical-proved anti-wrinkle skincare benefits.

Concurrently, the Perfect Diary Translucent Blurring Setting Powder features the exclusive Smartlock™ material technology developed jointly with the team at the Shanghai Institute of Ceramics, Chinese Academy of Sciences (SICCAS), enabling targeted and precise oil absorption.
