Hudson Yards to Clark, NJ!

Beauty born from science, and today I saw it. Thank you La Roche-Posay and L'Oréal Paris for hosting me for a behind-the-scenes look at the science behind La Roche-Posay’s new Anthelios UV Defense, launching October 20.

Why I'm excited as a dermatologist:
- Bemotrizinol (BEMT) is the 3rd FDA "generally recognized as safe and effective" sunscreen filter, after zinc oxide and titanium dioxide
- The first new U.S. sunscreen active in 20+ years
- Covers UVB, UVA2, and UVA1 and is highly photostable
- Low systemic absorption and no estrogenic activity in vitro
- FDA-permitted for adults and children 6 months and older
- Cell-Ox Shield antioxidant system (Litchiderm + Exo-P)
- More elegant formulas mean better protection for skin of color

UV Defense will be launching Oct 20!

20 miles, 3 bridges, and an overcast morning that still called for sunscreen.

Yesterday morning, I volunteered at check-in for the New York Flyers’ Three Bridges Run, handing out bibs and sunscreen to runners getting in one of their last big long runs before the NYC Marathon.

Thank you to La Roche-Posay for providing Anthelios UV Pro Sport sunscreen. Even on cloudy days, UV exposure still adds up, especially over several hours outdoors. Sweat and friction can also wear sunscreen down, making reapplication especially important during long runs.

Thank you as well to all of the volunteers who staffed the fluid stations, paced runners, and helped make the morning run smoothly, and to Fleet Feet Columbus Circle for hosting check-in. Marathoners, you’re almost there!

October is Eczema Awareness Month.

More than 31 million Americans live with eczema, and it's so much more than "dry skin." It can mean sleepless nights, constant itch, flares that show up at the worst times, and a lot of frustration with products that promised to help.

What I tell my patients:

- Think barrier first. Eczema skin loses moisture easily, so a fragrance-free moisturizer applied within a few minutes of bathing makes a real difference.
- Simpler is usually better. A gentle cleanser and a good moisturizer beat a 10-step routine on reactive skin.
- "Natural" doesn't always mean gentle. Essential oils and botanical extracts are common triggers.
- If over-the-counter care isn't enough, there are more treatment options than ever, including non-steroidal topicals, targeted oral medications, and biologics.

If you've been struggling in silence, this is your sign to get it evaluated. You deserve comfortable skin.

Save this for the next flare and share it with someone who needs it.

Happy Chuseok

Today is Chuseok, Korea’s harvest festival and one of my favorite Korean holidays. Families travel home, make songpyeon together, honor their ancestors, and gather around the table.

As “The K-Beauty Dermatologist,” I’m often asked what makes Korean skincare different. The answer is not one hero ingredient or even a 10-step routine. Much of it comes down to consistency, prevention, and caring for the skin over time.

In that way, Korean skincare has something in common with Chuseok. Both are rooted in traditions and rituals that are passed down through generations.

A few things I’m taking into fall from that same spirit:
- Repair, don’t attack. After a summer of sun, heat, and humidity, focus on supporting the skin barrier rather than over-exfoliating.
- Sunscreen doesn’t get a holiday. Cooler weather does not mean UV exposure disappears.
- Slow down. Your skin often benefits from consistency more than constantly adding something new.

To everyone celebrating, 추석 잘 보내세요. Wishing you a full moon and a full table.

And I have to ask, songpyeon or jeon?

As a dermatologist, this month always brings me back to something I talk about often but that doesn't get nearly enough airtime: skin of color deserves skin of color–specific care.

Melasma. Post-inflammatory hyperpigmentation. Sun protection that doesn't leave a white cast. These aren't niche concerns, they're everyday realities for so many of my Latina patients, and yet so much of mainstream skincare advice still defaults to research done on lighter skin types.

A few things I want more people to know:
- Melasma is incredibly common in Hispanic/Latina skin and often worsens with sun + hormones. It's manageable, not something to just live with
- SPF is non-negotiable regardless of skin tone (melanin built-in sun protection)
- Hyperpigmentation from acne or irritation heals differently in deeper skin tones and needs a gentler, more strategic approach

Representation in dermatology research and imagery matters, and so does having derms who actually understand your skin's unique needs.

Sunscreen history was made and I discovered it mid-trip.

I was recently in Australia and picked up Ultra Violette Skincare's Mini Mate Vibrant Screen SPF 50 while I was there. Around the same time, I learned Ultra Violette had launched Unblock Screen SPF 50 in the US, the first sunscreen in the United States to contain bemotrizinol (BEMT), the first new sunscreen filter the FDA has approved in more than 25 years.

It was a full circle moment. Ultra Violette has formulated with BEMT in its Australian and international range for close to a decade. Meanwhile, as a dermatologist, I've spent years advocating for US sunscreen filter modernization so American consumers could finally access what the rest of the world already had. Now that gap is closing, and I got to hold the "before" and read about the "after" in the same week.

BEMT is broad-spectrum, photostable, and effective at lower concentrations, which means lighter textures, less white cast, and more room in a formula for actual skincare benefits.

Star #7. 🌟

Last year, Sydney and I had unfinished business. I stopped at mile 24. This year, I went back and finished what I started.

7 of 8 Abbott World Marathon Majors down. Cape Town is the last one on my list, but Sydney was the one I needed to return to first after last year’s DNF.

26.2 miles has a way of reminding you that finishing is never guaranteed. Sometimes the most important part is simply being willing to show up again.

To anyone sitting with an unfinished race, a failed attempt, or a “not yet,” go back for it. Mile 24 wasn’t the end of this story. This time, I made it to the finish line.

I recently sat down with Dr. Patty Farris for the Science of Skin Summit podcast to talk all things K-beauty, from the science behind the trends to what is actually worth the hype.

We discussed how Korean skincare has influenced the way we think about skin barrier health, formulation, and daily routines, as well as where the evidence supports some of the most popular K-beauty trends and where it may not.

And if you have ever wondered whether you really need a 10-step routine, we talk about that too. The answer, of course, depends on your skin.

Thank you Dr. Patty Farris for having me and for such a thoughtful conversation.

I spent Labor Day weekend at the US Open with La Roche-Posay and my signature Honey Deuce!

Saturday evening, I watched a gripping three-set battle on the women’s side as Iva Jovic edged out Alexandra Eala 7-5, 3-6, 7-5 in a match that ran well past the three-hour mark, followed by No. 1 seed Alexander Zverev defeating Alejandro Tabilo in straight sets, 6-2, 7-6(2), 6-2.

UV exposure at outdoor sporting events is often underestimated. Hours of unbroken sun, reflected glare off hard courts and concrete, and sweat can all make sunscreen reapplication especially important, never mind during a three-hour match.

For days like this, I reach for La Roche-Posay’s Anthelios UV Sport SPF 50. It’s designed to hold up through sweat and activity without the heaviness or eye sting that can keep patients from wanting to reapply.

A good reminder heading into fall that UV damage doesn’t take a season off, and neither should your SPF habit!

Squeezing limes at a backyard party this summer? Here is something to keep in mind.

We recently saw a case of phytophotodermatitis, a skin reaction that can appear a day or two after certain plant or citrus juices come into contact with the skin and are then exposed to sunlight.

Limes, lemons, bergamot, figs, celery, parsley, and wild parsnip contain compounds called furocoumarins. When these compounds are exposed to UVA light on the skin, they can trigger a phototoxic reaction.

One of the biggest clues is the pattern. Rather than appearing like a typical rash, phytophotodermatitis often follows exactly where the juice touched the skin, creating drips, streaks, splashes, or even handprints.

What to expect:
- Redness and sometimes blistering, usually within 24 to 48 hours
- Burning or tenderness
- Brown discoloration afterward that can last for weeks to months

This is not an allergy, it is not contagious, and it is not “sun poisoning.” The reaction requires both the plant compound and UV exposure.

If it happens, use cool compresses and gentle skin care, protect the area carefully from the sun, and see a dermatologist if the reaction is significant. Sun protection is especially important afterward because UV exposure can make the lingering discoloration darker and more persistent.

And if you are cutting or squeezing citrus outdoors, wash your hands and any exposed skin thoroughly before heading back into the sun.
