Big news for sun protection in the US! The FDA just approved Bemotrizinol, also known as PARSOL Shield, a UV filter that has been used in Korea, Japan and around the world for years.

This is a huge deal for American skin health and here’s why it matters:

- Broader UVA + UVB protection
- More photostable protection in sunlight
- Potential for lighter, more elegant sunscreen textures
- A major step toward closing the gap between US sunscreens and global sun care innovation

As a dermatologist and health policy advocate who has advocated on Capitol Hill for this kind of regulatory progress, I am so proud of everyone who helped push this forward.

Skin cancer is the most common cancer in America, and sunscreen is one of our most powerful prevention tools. Better filters can mean better formulas, better daily use, and better protection.

Just got back from an incredible weekend in Dallas, Texas, where I attended the TikTok Shop K-Beauty Collective Pop-Up as the medical dermatologist for Dr. Groot Hair!

Hosted by TikTok Shop, the K-Beauty Collective brought together 20+ top K-beauty brands flying in directly from Korea for two full days of product discovery, exclusive previews, and conversations with brands, creators, and consumers who are just as excited about Korean beauty innovation as we are.

We were especially proud to represent Dr. Groot, South Korea’s No. 1 hair thickening brand and part of the LG Beauty portfolio. As scalp care continues to become one of the most exciting frontiers in K-beauty, I loved helping bridge the gap between beauty, hair health, and the clinical science behind it.

This is exactly what being “The K-Beauty Dermatologist” is all about: bringing dermatologic credibility into the spaces where skincare culture, haircare innovation, and science meet.

Back on campus this past weekend for my MIT 25th reunion.

There is something humbling about returning to a place that shaped how you think, a quarter-century later, and seeing how much further the work has gone. No more Athena clusters, a Banana Lounge across from 26-100, and now MIT.nano.

My first stop was to see my former UROP professor and eminent researcher, Dr. Elazer Edelman, followed by Professor Jeehwan Kim, who is doing incredibly exciting work in e-skin technology.

I spent Saturday morning at MIT Technology Day 2026 in Kresge Auditorium for “Our Next Era of Possibility: How MIT Is Redefining Intelligence, Computing, and Discovery.” The program brought together faculty leading the MIT Generative AI Impact Consortium and the MIT Quantum Initiative to discuss how breakthroughs in AI and quantum computing are reshaping science, industry, and society.

We capped the weekend with a brunch hosted by MIT President Sally Kornbluth, followed by our reunion class photo.

Twenty-five years later, MIT is still doing what it does best: asking what is possible, then going and building it. Grateful to this community, and to a place that still asks the hard questions.

This morning, I had the privilege of visiting the L'Oréal Research & Innovation Center in Clark, NJ, at the invitation of the SkinCeuticals Medical Affairs team.

I was joined by an exceptional group of colleagues, including Dr. Jared Jagdeo, Dr. Kachiu Lee, Dr. Amanda Doyle, Dr. David Shafer, and Dr. Jennifer Levine, for a behind-the-scenes look at the R&I process driving some of the most evidence-based topical formulations on the market.

The visit included an overview of L'Oréal's research and innovation pipeline, a facility and lab tour, and deep dives into advanced research and ingredient science.

As a board-certified dermatologist, understanding the translational science behind the products I recommend is essential, and today delivered exactly that. Particularly relevant to my practice was the science behind Age Interrupter Ultra Serum and the formulation rigor that supports its clinical positioning.

This is the kind of evidence-based foundation that informs how I counsel patients on cosmeceutical adjuncts to in-office treatments.

Grateful to SkinCeuticals and the L'Oréal Medical Affairs team for this rare and genuinely educational experience.

New York Tech Week starts today, and I’m kicking it off where I find the most interesting questions live: the intersection of AI, healthtech, and the realities of delivering care.

Tonight I'm joining BioLabs @ NYU Langone, Orbiss, and MedRock Ventures for "AI & HealthTech for Hospitals and Healthcare," bringing together hospital leaders, healthtech founders, and investors for a candid panel and live startup pitches.

Great lineup of voices on stage, including Eric Noonan (Memorial Sloan Kettering), James Hamet and Dr. Samy Merad, PharmD (MedRock Ventures), and Jenny Le Doridour (Orbiss).

As a physician, what excites me most is not just the demos. It is the harder, more meaningful work: how these tools integrate into clinical workflows, navigate regulatory pathways, and earn the trust of the people who use them every day. That is where the real progress happens.

Looking forward to the panel and the innovation showcase. If you’re attending, let’s connect.

Yesterday afternoon, I joined VisualDx for a webinar sponsored by Vaseline to talk about post-procedure wound care, common healing myths, and the role of petrolatum in supporting the skin barrier.

We discussed evidence-based post-procedure regimens and how simple barrier support can make a meaningful difference in the way skin heals after procedures.

In my office, I emphasize clear consent, realistic expectations, and proper wound care. For many post-procedure patients, consistency with products like petrolatum can help support the skin barrier and protect the healing process.

Thank you to VisualDx and Vaseline for the opportunity to be part of this important clinical education discussion.

Happy National Sunscreen Day!

There is no better day to talk about sunscreen, especially after joining Skin of Color Savvy, the official podcast of the Skin of Color Society, for an episode titled “The Sunscreen Gap: Cancer Prevention in Skin of Color.”

Skin cancer can affect anyone, regardless of skin tone. Melanoma in skin of color is often diagnosed later, in part because it can appear in places we may not think to check, including the palms, soles, under the nails, and other less visible areas.

And when patients with deeper skin tones avoid older sunscreens because of a white or gray cast, that is not vanity. It is not “non-adherence.” It is a formulation failure. The good news is that sunscreen science is evolving, with more cosmetically elegant options, tinted formulas, iron oxides, and broader conversations around access to newer-generation UV filters.
The best sunscreen is the one you will actually wear consistently.

Thank you to SOCS President Dr. Rebecca Vasquez, SOCS Founding Member Dr. Henry Lim, and Dr. Jeanine Downie for this important conversation on skin cancer prevention, delayed diagnosis, sunscreen adherence, and health equity in skin of color.

This episode highlights the importance of closing persistent gaps in skin cancer prevention and awareness for patients with skin of color.

May is AAPI Heritage Month, and as a Korean American dermatologist, it is a month I hold with both pride and purpose.

So much of my work lives at an intersection that feels deeply personal: the clinical science of dermatology and the rich tradition of Korean and Japanese skincare. K-beauty and J-beauty are often framed as trends. I see them differently, as heritage, as craft, and increasingly as a source of genuine formulation innovation. Some of the most cosmetically elegant, broad-spectrum UV filters in the world are found in Korean and Japanese sunscreens, and the U.S. is still working to catch up.

But Heritage Month is also a moment for an honest message. AAPI patients have the lowest 5-year survival for advanced-stage melanoma of any group in the U.S., despite low overall incidence. Skin cancer in skin of color often appears where we do not think to look, including the palms, soles, and under the nails. The myth that darker skin is “fully protected” can delay diagnosis on both sides of the exam table.

Celebrating our heritage and protecting our health are not separate projects. They are the same one.

To my AAPI colleagues, patients, and community: I am grateful to do this work alongside you.

After a beautiful K-Beauty Immersion Day at the Javits, I was invited to a dinner at Gaonnuri, 39 floors above Manhattan, hosted by IOPE.

IOPE launched in the US this March, and if last night was any indication, they came ready. Korea’s #1 anti-aging brand brings clinical-grade formulations built around ingredients I already discuss with my patients, including PDRN for regeneration and barrier repair, as well as a 2% retinol delivery system designed to be effective while minimizing the irritation that often makes patients stop using retinoids.

The view was stunning. The science was even better.

Yesterday at NYSCC Suppliers’ Day (), I had the privilege of curating and moderating the first dedicated K-Beauty program, K-Beauty Immersion, at a major US cosmetic science conference.

What I wanted the room to understand: K-beauty is not a trend to be managed. It is a lens through which some of the most rigorous thinking in skincare has happened. Barrier science. Anti-inflammatory formulation. Early intervention. UV filter innovation that puts US photoprotection to shame.

We covered all of it, from market signals with Spate () and NielsenIQ (), to clinical translation in my own session on evidence-based K-beauty routines and outcomes, to skin-of-color inclusion with L’Oréal (), to the SPF regulatory frontier with dsm-firmenich () on bemotrizinol.

Visionary founder Charlotte Cho () reminded the room why cultural conviction and scientific integrity are not opposites.

The science panel brought it home: Amorepacific () broke down what is actually behind the PDRN, spicule, and exosome buzz, and what the data does and does not support. LG H&H (.lghh) pulled back the curtain on why K-beauty textures feel so different from everything else on the market: the emulsion science, the sensorial engineering, and the formulation philosophy that drives adoption and adherence.

The supplier panel, SEPPIC (), INOLEX (), BASF Personal Care (), and COSMAX (.global), did not just talk innovation. They brought it. Attendees walked the show floor and experienced these ingredients firsthand: the textures between their fingers, the actives on their skin, and the scents in the air. That sensory dimension is something no slide deck can replicate, and it made everything we discussed in the room suddenly tangible.

The conversation the US cosmetic industry needed to have. I’m proud we started it.
