Diana Seo, founder and president of Collagen Bar NYC, has built her reputation on science-driven, results-oriented skincare. With a background in biophysics and decades of experience working alongside leading plastic surgeons, Seo approaches skin health with a focus on structure, precision, and long-term support. Locations include the flagship in Gramercy Park, as well as offices at the Lotte New York Palace’s Ila Spa in Midtown, the Sixty LES Hotel on the Lower East Side, Dr. Jonathan Sherwyn’s offices on the Upper East Side, and at Plastic Surgery of Westchester in Harrison.
We spoke with Diana about collagen stimulation, advanced treatments, and the future of non-surgical aesthetics.
Your background is rooted in science. How did that shape your approach to skincare?
My foundation is in biophysics and cytogenetics, so I’ve always viewed skin as a living system rather than something to treat superficially. Early in my career, working with plastic surgeons, I saw how deeply structure and collagen integrity influence the face over time. That experience shaped my philosophy. I’m not interested in quick fixes. I focus on supporting the skin’s ability to renew itself.
Collagen stimulation has become a buzzword. What does it really mean?
Collagen gives skin its strength and elasticity. As we age, production slows. The goal isn’t dramatic overnight change — it’s gradual rebuilding. We use controlled energy-based treatments to stimulate collagen at different depths, encouraging the skin to strengthen itself naturally.
Your treatments incorporate radiofrequency technologies. What makes them effective?
Radiofrequency delivers controlled heat into deeper layers of the skin, signaling the body to produce new collagen and elastin. Because we can treat at multiple depths, we address both surface texture and deeper laxity. It’s precise and customizable, which is key to achieving natural-looking results.
One of your most talked-about treatments is the Salmon DNA facial. Why has it resonated?
The name gets attention, but the science is what matters. Polynucleotides derived from salmon DNA support hydration and cellular repair. When combined with microneedling or energy-based treatments, they enhance renewal at the cellular level. Clients notice smoother texture, improved elasticity, and a healthy, lasting glow.
How do you see the future of non-surgical aesthetic treatments evolving?
We’re moving toward regeneration and longevity. Clients want treatments that preserve their natural features rather than dramatically alter them. The future of aesthetics is about supporting biology — working with the skin instead of against it.
For women balancing full lives in New York, what does good skincare look like today?
Consistency and prevention. It’s less about trends and more about long-term care. When you maintain collagen and manage inflammation, the skin looks lifted and radiant in a very natural way. That kind of confidence doesn’t require excess — it requires precision.
