Behind every treatment is a doctor who’s asking questions, studying the science, and refining the approach.

At UnionDerm, our physicians are constantly engaging with the science behind what we do — on stage, in research, and in every patient interaction. Because innovation doesn’t just happen in the treatment room, it’s built through curiosity, conversation, and a commitment to doing things better.

Today we’re celebrating the minds driving our field forward — in the office and far beyond it. Happy National Doctors’ Day to the innovators behind the work. ✨

These are real words from real patients—and we don’t take that trust lightly. 🤍

For Dr. Ugonabo, the goal is always for you to feel heard, comfortable, and confident in your skin. Great care is about more than results. It’s about feeling confident, understood, and completely at ease throughout the process. Dr. Ugonabo believes every visit should feel like a conversation, not just an appointment.

If you’ve been considering a consultation, this is your sign to book. ✨

Hyperpigmentation is one of the most common concerns I treat — and one of the most rewarding to see improve.

With PicoWay, I can precisely target and break down unwanted pigment without damaging the surrounding skin. The result: clearer, more even tone with minimal downtime.

Every treatment plan starts with a consultation — because not all pigmentation is the same, and the approach shouldn’t be either.

We just set the clocks forward an hour — which always makes us think about setting the clock back on skin aging.

One treatment we love for improving skin firmness, lifting, and laxity is the Miria laser.

🕒 Fractional laser energy stimulates new collagen and elastin
🕒 Helps the skin become firmer, tighter, and lifted
🕒 Softens folds and fine lines while restoring subtle volume
🕒 Improves crepey texture and overall skin quality

Best part: it’s completely non-invasive — no surgery, no needles, just your skin rebuilding itself from within.

Ulthera is one of my favorite treatments for lifting and tightening the skin—but pairing it with the right injectable can enhance the overall result. Here’s a combination I often recommend to my patients:
✨ Ulthera uses focused ultrasound energy to stimulate collagen in the deeper layers of the skin, helping lift and tighten areas like the jawline, cheeks, and neck.
✨ I often pair it with diluted Radiesse, a biostimulatory filler that helps stimulate new collagen in the skin itself, improving firmness and overall skin quality.
✨ Together, they work at multiple levels of the skin—Ulthera providing deeper structural tightening, while Radiesse supports collagen production closer to the surface.
✨ Results develop gradually as your body builds new collagen, creating firmer, healthier-looking skin over time.
I love this approach because it allows me to address tightening more comprehensively while still keeping results natural-looking.

I’m excited to be seeing patients this spring at our newest, state-of-the-art Greenwich location.
I’ll be in Greenwich on February 25, March 4, and March 11, with a focus on cosmetic dermatology, including injectables and energy-based treatments.

I won’t be accepting new general dermatology patients in Greenwich at this time; however, existing patients are welcome to book follow-up care during these dates.
Appointments are limited, so be sure to book soon!

What’s my favorite treatment to pair with Fraxel for comprehensive anti-aging? ✨
The answer: Sofwave.

✨ Fraxel targets skin quality — improving texture, tone, fine lines, and pigmentation by stimulating collagen from the surface down.

✨ Sofwave works deeper, using ultrasound energy to tighten and lift by stimulating collagen in the mid-dermis.

✨ When combined, these treatments address both skin renewal and skin tightening, creating more balanced, natural-looking rejuvenation without surgery or downtime-heavy procedures.

This is one of my go-to combinations for patients looking to improve skin texture and firmness in a thoughtful, evidence-based way.
