Here is a before and after of a patient with localized scalp morphea who experienced significant hair regrowth after treatment with oral and topical JAK inhibitors. Morphea is a rare immune-driven condition that causes firm, discolored patches of skin that can become thickened over time. When it affects the scalp, the inflammation and fibrosis can damage hair follicles, making hair growth difficult or impossible in the affected area.

This patient had a longstanding patch on the scalp that led to noticeable hair loss and a lot of self-consciousness. After starting a combination of oral JAK inhibitors, including oral upadacitinib (Rinvoq) and ruxolitinib cream (Opzelura), to target the underlying inflammation and soften the sclerotic tissue, we began to see new hair growth within the first few months. Here, at the eight-month mark, the improvement was even more visible, with continued regrowth and no progression of the morphea plaque.

Although more studies are needed, early results like this are promising for patients with inflammatory and scarring conditions that impact quality of life.

Spent the weekend volunteering for the 32nd Annual Race to Deliver 4M in Central Park with to support . It was a beautiful day to aid thousands of runners coming together for a cause that means so much. God’s Love We Deliver prepares and delivers medically tailored meals to New Yorkers too ill to shop or cook, providing a lifeline of nutrition, care, and dignity. Last year, the organization delivered over 3.3 million medically tailored meals to almost 11,000 New Yorkers who rely on this essential support.

I also celebrated My Best Winter Skin Day with my fellow NYRR medical volunteers, an initiative from the Skin of Color Society that raises awareness about how to protect and care for skin during colder months. With winter’s dry air and wind, SOCS emphasizes basics like moisturizing daily, choosing thicker creams, using gentle cleansers, covering up, and remembering sunscreen. Thank you to for leading this valuable campaign and helping bring dermatologist-led education to communities everywhere.

Curious how ultrasound is reshaping aesthetic dermatology? At our office, we use high-resolution ultrasound imaging to see dermal fillers beneath the skin in real time. Here, we are using ultrasound to check the placement of a patient's under eye filler and how it interacts with surrounding anatomical structures.

Ultrasound guidance is especially valuable for filler dissolution. By pinpointing the precise location of the product, we can target hyaluronidase with accuracy, improving both safety and effectiveness. This approach is particularly helpful in areas like the under eyes, where anatomy is delicate and precision is essential.

What makes ultrasound helpful?
- Real-time visualization of filler placement
- More precise and predictable filler dissolution
- Better understanding of facial anatomy beneath the surface
- Supports safer, more individualized aesthetic treatments

Tools like ultrasound help us tailor procedures, refine outcomes, and provide patients with greater clarity and confidence throughout the treatment process.

Proud to have teamed up with the Skin Cancer Foundation () in advocating for the SAFE Sunscreen Standards Act, and thrilled to share that the legislation was officially signed into law on November 13, 2025. This is an important step toward giving Americans access to newer, safer, and more effective sunscreen filters that can help prevent skin cancer and save lives.

The Act modernizes how the FDA evaluates sunscreen ingredients by requiring clearer and more flexible testing standards, aligning U.S. regulations with international procedures, and directing the FDA to review and approve new and globally used sunscreen filters. These updates expand access to advanced, effective ingredients and support long-overdue innovation in sun protection.

Here’s a before and after of a patient who underwent PICO laser treatment for freckles and solar lentigos on her face. This result is after just one treatment. She was thrilled to see the larger and darker sun spots fade while still preserving the lighter freckles that give her skin its natural charm!

Freckles, also known as ephelides, are small light to dark brown macules that commonly occur in fair-skinned individuals and often become more noticeable with UV exposure. Solar lentigos, or sun spots, develop over time due to cumulative sun exposure and tend to persist unless treated. PICO laser can effectively target both, helping create a clearer, more even complexion without removing all the unique features that make someone’s skin theirs.

And this season is one of the best times to treat pigmentation concerns! Winter brings shorter days, heavier clothing coverage, and a lower UV index, which supports healing and reduces the risk of unintended darkening after laser treatments.

As always, diligent sun protection remains essential. Daily broad-spectrum tinted sunscreen helps protect results and prevents pigment from returning.

The ASDS Annual Meeting begins today in Chicago, Illinois (November 13 to 16), and I am excited for a full weekend of education, innovation, and connecting with colleagues in aesthetic dermatology and dermatologic surgery. I am honored to be serving as a session director for AI applications in aesthetics, and will also be speaking on the digital skin revolution and presenting on imaging in dermatologic surgery and aesthetics using ultrasound.

From advances in procedural safety to the newest techniques and technologies, the ASDS continues to shape the future of our specialty. Looking forward to the conversations and collaboration ahead.

Saw the musical Ragtime this weekend at Lincoln Center Theater. Ragtime is a sweeping musical adaptation of E.L. Doctorow’s novel that follows three fictional families in pursuit of the American Dream at the dawn of the 20th century: Black pianist Coalhouse Walker Jr. and his beloved Sarah, Jewish immigrant Tateh and his little girl, and a wealthy white family led by matriarch Mother. All grasping for the same dream, if only they can hold on to it.
It’s a story about who gets to belong, the dignity of work, the cost of progress, and the intersections of race, immigration, and power, told with music that still lands like a warning and a hope.

In a week of heavy headlines, it felt less like nostalgia and more like a civic prompt to listen harder, widen the circle, protect the vulnerable, and do the unglamorous work to vote, volunteer, and show up.

On this Veterans Day, taking a moment to honor those who have served and sacrificed, protecting the ideals of freedom, resilience, and belonging that stories like Ragtime remind us to cherish.

Last week I attended LG Beauty () Bojagi Workshop, a holiday gifting event built around traditional Korean Bojagi wrapping, taught by the Hanulbo Academy ().

Bojagi is a square fabric traditionally used to wrap, cover, and carry belongings. It embodies the heartfelt wish to wrap and share blessings. Each knot represents the philosophy of care and inclusiveness passed down from Korean ancestors, transforming Bojagi into a versatile art form that can be used in everyday life.

Ladies from the House of Three () taught us how to elegantly wrap products from belif (.official), THE FACE SHOP (.official), Dr. Groot (.groot_official), The Crème Shop (), and Euthymol (.official) with lotus, hydrangea, and chrysanthemum knots.

This holiday season, as we spend time with loved ones, let’s take a moment to be thankful and wrap our blessings with the same care and intention!

Spent last night with renowned, influential photographer Annie Leibovitz in a private exhibition tour and discussion in which she offered insights into her seminal work, Women. Celebrating the individual power of each woman with their portraits projected onto the huge white walls of Studio 525 was awe inspiring, featuring dancers, actors, astronauts, artists, politicians, farmers, writers, CEOs, philanthropists, soldiers, musicians, athletes, socialites, and scientists.

This essential visual record of women comes at a moment in history that has never been more urgent, with changing women's rights and the future challenges of the next generation. An exhilarating and unforgettable evening to end the week!

Curious about the hottest new innovation in K-Beauty skin tightening? Today we’re showcasing the EVERESSE device by .inc, a non-invasive treatment designed to lift and firm the skin with precision and comfort.

Here’s a live demonstration of treatment along the jawline. EVERESSE uses monopolar radiofrequency technology with continuous water cooling. This combination allows for deep, controlled heating in the dermis while protecting the surface of the skin, which makes treatments both effective and comfortable.

The result is immediate tissue contraction with ongoing collagen remodeling in the weeks and months that follow. Areas like the jawline, where early laxity often appears, are especially responsive to this type of treatment. EVERESSE can also be used on the neck, around the eyes, the lips, and even the body, areas where skin is thinner and early changes in elasticity tend to show.

What makes it unique:
- Continuous water cooling that keeps treatments safe and comfortable
- Real-time contact detection and a curved tip that allow for even energy delivery
- Versatility to treat multiple areas, from face and neck to more delicate zones like around the eyes and lips
- Safe for all skin types without downtime

As more patients seek non-invasive ways to maintain skin health, EVERESSE adds another strategy to stimulate collagen and improve elasticity over time.

This Sunday, I’ll be on the start line of the TCS New York City Marathon . Before that, I’ll be volunteering at the Parade of Nations in Central Park, celebrating athletes from around the world in a vibrant procession of global unity and diversity.

Tomorrow’s Abbott Dash to the Finish Line 5K kicks off from the United Nations and winds past Grand Central Terminal and Radio City Music Hall into Central Park, finishing at the iconic TCS New York City Marathon finish line.

Training for this race begins in the summer, so what you’ll see on Sunday is months of early mornings, long runs, and careful pacing, fueling, and recovery. Grateful for the friends who kept me consistent and accountable through it all. Sunscreen is packed, chafe balm and pace band ready, and I’m excited to soak it all in. Thank you for the blinged bottles!

Running through five boroughs means crossing multiple bridges, but it’s one incredible city. Volunteers, spectators, and thousands of runners come together to create a moving city of kindness, grit, and resilience.

That NYC energy is unmatched. The TCS New York City Marathon embraces runners of every pace, background, and story, and no one gets left behind. There’s no better feeling than knowing we’ll all come together on race day. 26.2!
