On behalf of the Chinese Society for Investigative Dermatology (CSID), it is my great pleasure to welcome you to Shenyang for the 9th Annual Meeting of CSID. We are thrilled to gather once again in person to celebrate and advance the science of dermatology together.

Dermatology is a field vibrant with innovation, and 2025 marks a year of remarkable transformation. This meeting brings together cutting-edge research at the forefront of cutaneous biology and clinical practice—from immunology, oncology, and skin barrier science to epidemiology and novel therapeutics. The diversity and depth of our program reflect the dynamic progress of our specialty.

More than a series of presentations, this meeting is a platform for collaboration and inspiration. I encourage each of you—whether an established expert or an emerging investigator—to actively engage, exchange ideas, and build connections. It is through these interactions that we will spark the next wave of breakthroughs.

We are honored to host world-renowned keynote speakers and offer a range of symposia and workshops designed to explore new concepts and clinical strategies. New formats for oral and poster sessions this year will also provide fresh opportunities for researchers at every career stage to share their work.

Nurturing the next generation of dermatologists and scientists remains essential to our mission. The young researchers present today will undoubtedly lead the future of our field, bringing new energy and vision.

Beyond the science, Shenyang—a city rich in history and culture—offers a stimulating environment for reflection and networking. I hope you take time to explore its unique charm and enjoy meaningful conversations with colleagues.

Welcome to CSID 2025 in Shenyang! Let’s make this an inspiring and unforgettable gathering dedicated to science, collaboration, and the future of dermatology.

On behalf of the organizing committee, we warmly welcome all attendees, speakers, and exhibitors to the historic and dynamic city of Shenyang for the 2025 CSID Annual Conference—this year’s premier gathering in dermatology. We are grateful for your commitment to advancing our field and for bringing your expertise and perspectives to this global forum.

The skin, our largest and most visible organ, safeguards human health and serves as a vital barrier to the external environment. This conference provides a unique platform for researchers, clinicians, and industry partners to exchange insights, challenge assumptions, and accelerate translation from discovery to practice. Together, we aim to deepen our understanding of skin biology and disease—from molecular mechanisms to population health.

Our scientific program spans molecular biology, regenerative medicine, immunology, allergy, biochemistry, and the emerging applications of artificial intelligence in dermatology. Highlights include late-breaking clinical data, consensus discussions on standards of care, and sessions that showcase real-world evidence and implementation science. The knowledge exchanged here will strengthen clinical practice and ultimately improve patient outcomes and public health.

This year, we convene hundreds of distinguished speakers selected for their excellence and impact. Attendees can expect inspiring keynotes, rigorous oral presentations,

interactive workshops, case-based discussions, and vibrant poster sessions, alongside meet-the-professor events and young investigator spotlights designed to nurture the next generation of leaders.

We invite you to join us in Shenyang—where tradition meets innovation—to explore new horizons, forge meaningful collaborations, and spark ideas that move our specialty forward. May your time here be productive, collegial, and memorable.

Welcome to the 2025 CSID Annual Conference — where the world is, there we are!
