We’re thrilled to welcome Dr. Jameson Loyal to UnionDerm! His first day seeing patients is Friday, October 9th.
“Dr. Loyal brings exceptional depth to our team, from advanced laser resurfacing and injectables to hair restoration. Like all of us at UnionDerm, he believes great results start with a real conversation. He takes the time to understand each patient’s goals and builds a thoughtful, individualized plan to get them there.
His commitment to research and evidence-based care, including more than 50 clinical trials, fits naturally with everything we do here. We’re so glad he chose to come home to New York and join us, and we can’t wait for patients to experience his expertise and care.”

A decade of care. Consistently natural results. 🤍
Dr. Claire Chang has a gift for making even the most nervous patients feel completely at ease. Her hand is gentle, her approach is honest, and she takes the time to actually explain what’s happening — the science, the recovery, the realistic timeline.
We could tell you why patients keep coming back for 10+ years. Instead, we’ll let their words do it. Swipe through a few of our favorites. ✨

Same technology. Different treatment plans. Incredible results.
Every case of hair loss is different, which is why these two UnionDerm patients received personalized treatment plans centered around Folix. Whether you’re just starting to notice thinning or have been dealing with hair loss for years, an expert evaluation is the first step toward finding the right solution.

As my ASDS fellowship year comes to an end, I’m thrilled to share that I’ll be staying on at UnionDerm as an attending physician.
To the patients who trusted me with their care this year — thank you, from the bottom of my heart. Being part of your journey has been such a privilege, and I’m so looking forward to continuing to care for both new and existing patients across our Greenwich, Central Park, and Union Square offices.
I’m deeply grateful to Dr. Chapas and the physicians who poured into me and invested in my growth this year. This chapter has meant more than I can put into words — and I cannot wait for what’s next!
With gratitude 🩵

One of the best parts of having a fellowship program is getting to work closely with talented young physicians at such an important stage in their careers. From the beginning, it was clear that Dr. Humphrey was someone special.
She is thoughtful, hardworking, incredibly detail-oriented, and deeply committed to her patients. Over the past year, I’ve had the privilege of watching her grow as a cosmetic dermatologist, and I couldn’t be happier that she has chosen to stay at UnionDerm.
We are thrilled to welcome her to our attending physician team and excited for our patients to continue benefiting from her expertise and care.

Our team had a ball last night 🎾⛳️
A little friendly competition, a lot of laughs, and absolutely zero surprise that our dermatologists ended up being great at the games too. From lawn pong and corn hole to cocktails, snacks, and nonstop commentary, Lawn Club was the perfect excuse for some team building outside the office. Nothing better than a night with the UnionDerm crew 💙
