I am excited to be in Hamburg, Germany for the Global Skin Longevity Summit by , hosted at the headquarters and taking place February 10–11, 2026. This global meeting brings together more than 300 dermatologists from around the world to explore the evolving science of skin longevity, with a strong focus on epigenetics, aesthetic treatments, and long-term skin health.

I’m also looking forward to the dedicated Hyperpigmentation Masterclass on February 12, which will highlight the latest clinical findings and therapeutic approaches for managing hyperpigmentation across diverse skin tones.

Grateful to for the invitation and for continuing to foster thoughtful, science-driven conversations that advance dermatologic care worldwide.

February is Black History Month, a time to celebrate Black history, culture, creativity, and leadership, and to honor the profound impact Black individuals have had and continue to have across medicine, science, advocacy, and community care. It is also a moment to recognize resilience, excellence, and the ongoing contributions that shape healthier and more equitable futures.

In dermatology, one important and often overlooked issue is skin cancer in skin of color. While skin cancer is less common in Black patients, it is more likely to be diagnosed at later stages, which can lead to worse outcomes. Contributing factors include misconceptions about risk, fewer routine skin exams, and limited awareness that skin cancer can present differently in darker skin, sometimes appearing in areas not typically associated with sun exposure.

Representation also matters. Many skin conditions are still primarily taught and shown on lighter skin tones, which can make it harder for both patients and clinicians to recognize disease in darker skin. Improving representation in medical education and clinical care is an essential step toward earlier diagnosis, better outcomes, and stronger patient trust.

Everyone, regardless of skin tone, deserves education, access to care, and representation in medicine. This month and every month, we remain committed to inclusive dermatologic care and patient education.

It was great being back in Paris for IMCAS World Congress 2026. I had a wonderful time speaking this year and reconnecting with colleagues and friends from around the world.

IMCAS continues to be an incredible space for thoughtful conversations around innovation, technology, and aesthetics. Some highlights included trying out my Meta glasses in French, volunteering AGAIN as the ultrasound demo patient, and filming an interview for the IMCAS academy.

Outside the congress halls, I loved exploring the largest French pharmacy in Paris and building a very solid product haul, and, of course, eating some delicious croissants and macarons.

Always grateful for the science, the energy, and the global community that makes IMCAS so special.

Last week, I had the opportunity to attend New Year, New You! Powered by K-Health at , a timely conversation exploring how Korea’s rapidly advancing health and biotechnology sectors are shaping the future of wellness and care.

The discussion highlighted the growing intersection of AI-enabled diagnostics, precision medicine, and cross-border collaboration, and how innovation in K-Health is influencing not only patient care, but also how health systems, startups, and institutions work together globally.

It was a pleasure to hear from an impressive panel, including William Ban, Co-Founder and COO of Himedi (), Taesoo Sean Kim, Partner at Ice Miller and Co-Chair of the firm’s Asia-Pacific Practice Group, and Ken Nesmith, Group Head of Oncology at Lunit, each bringing a distinct perspectives on how Korean health-tech companies are engaging with the U.S. healthcare landscape, from navigating regulatory and legal frameworks to building meaningful partnerships that ultimately shape how care is delivered.

Grateful for spaces like this that foster thoughtful dialogue at the intersection of medicine, technology, and global health, and for organizations like that continue to convene meaningful conversations around where healthcare is headed next.

Hearing that the U.S. has left the World Health Organization feels deeply disappointing, not just as a physician, but as someone whose first real “on the ground” public health experience began at the WHO.

As a graduate student in Health Policy at Harvard, my first real-world internship brought me into global HIV/AIDS work at a moment when the world was fighting for something urgent and tangible: access, scale, and lives.

I had the privilege of contributing to the WHO’s 3x5 initiative, working under Dr. Jim Kim, with a mission that felt almost impossible at the time: getting 3 million people on antiretroviral therapy by 2005. It was ambitious, imperfect, and yet profoundly human.

That experience shaped my belief that global health is not abstract. It is not “somewhere else.” It is deeply connected to our local health systems and our communities, and as I saw firsthand, it relies on working with governments across varied political ideologies to get much-needed medications and supplies on the ground.

The WHO is not flawless. No large institution is. But turning away from global cooperation in health feels like stepping backward at exactly the moment we need stronger surveillance, stronger trust, and stronger infrastructure.

As a dermatologist, I am reminded constantly that health is never siloed. Skin reflects systemic inflammation, stress, access, equity, and chronic disease. Public health is not separate from medicine. It is the foundation beneath it.

I am grateful for what I learned at the WHO, and I remain hopeful that we find our way back to collaboration, science, and shared responsibility.

Because viruses do not recognize borders, and neither should our commitment to health.

Years ago, I bought Google Glass, drawn to the idea that computing wouldn’t always live in our pockets. It felt exciting and awkward at the same time, very ahead of its moment, even if the world wasn’t quite ready for it yet.

This past snowy Saturday, I walked into the Meta Store on Fifth Avenue to buy the Meta Glasses paired with the Neural Band. The space felt calm and intentional, a contrast to my first visit when curiosity and crowds filled the room. This time, it felt unhurried.

I brought my Google Glass with me.

Standing there, I tried on both the past and the present just a few feet apart. That moment landed more deeply than I expected. Google Glass still felt like a prototype from the future, while the Meta Glasses felt designed for now. They don’t announce themselves or demand attention. They feel like thoughtfully made glasses that fit naturally into everyday life, and pairing them with the Neural Band only reinforced that sense of subtlety, lower friction, and intention.

What struck me most wasn’t everything the technology could do, but how much it has learned when to stay out of the way.

Walking back out into the snow, it became clear that this wasn’t just about buying new hardware. It was about watching an idea mature, and seeing something I believed in years ago finally arrive in a form the world is ready for.

Sometimes being early isn’t wrong, it’s just early. This time, the future feels ready, and I’m excited to be wearing it again.

Today we honor the life and legacy of Dr. Martin Luther King Jr., whose vision of justice, dignity, and equity continues to shape the work we do. His leadership reminds us that meaningful progress requires intention, service, and a willingness to examine the systems that affect people’s lives and health.

In healthcare, his message remains especially relevant. Equity goes beyond equal treatment and speaks to access, representation, and trust. It means recognizing how social and structural factors influence outcomes and committing to care that listens, understands, and serves diverse communities with respect and compassion.

On this MLK Day, we reflect on how his legacy calls us to continue this work through service, accountability, and action, every day.

If you’ve ever wondered how closely medspas are actually regulated, new reporting out of New York City offers an important reality check.

A New York City Council Oversight and Investigations Division report released in December 2025 detailed the results of inspections conducted between June and September 2024 at 15 medspas across all five boroughs. Every single location inspected was found to be out of compliance with state laws governing medical procedures.

Key findings from the report included:

- All inspected medspas were offering medical procedures without proper licensure
- 93% failed to properly display required licenses
- 73% operated without a medical professional present
- 86% lacked required safety records
- Over half had sanitation or hygiene violations, along with chemical or fire safety concerns
- Several cases have already resulted in license revocations

Following the release of this report, the American Academy of Dermatology Association and the New York State Society of Dermatology and Dermatologic Surgery issued a joint statement urging New York State lawmakers to strengthen medspa oversight. Their recommendations focus on clearer disclosure for consumers, stronger enforcement, and public education so patients understand which procedures non-physician facilities are legally prohibited from performing.

As a board-certified dermatologist, these findings highlight why medical procedures, even when considered “cosmetic,” require proper training, licensure, and on-site physician oversight. Treatments involving injections, lasers, or energy-based devices are safest when performed in a medical setting by or under the direct supervision of a licensed physician.

As medspas continue to grow in popularity, transparency and patient education are critical. Knowing who is performing your treatment, and under what medical supervision, matters.
