We believe in precision over pressure, and enhancement over excess. This is aesthetic medicine with purpose and with heart.




Our Core Values

Hospitality First
We greet you by name, listen with intent, and take the time to understand your story, treating you like the honored guest you are.

Medical Integrity
Our team of professionals has mastered the art and science behind subtle enhancement, offering treatments rooted in evidence—not trends.

Long-Term Loyalty
We look beyond the instant gratification of a single treatment, offering comprehensive care that evolves with your changing needs and aspirations.

Two Locations,
One Vision
Wherever you visit us, you feel known, receiving the attention and expertise you deserve.
Where heritage and healing converge, we offer luxury care with soul in the city’s most elegant enclave.
This modern sanctuary blends sleek design with cutting-edge skin and wellness solutions that reveal your best self.

Loyalty That Pays Off
At our medspa in the Upper East Side, NYC, we’re just as invested in your journey as you are. Aion’s loyalty program rewards your commitment by turning your monthly deposits into credits that never expire, alongside exclusive savings and perks.

You’re More Than a Client
At Aion Aesthetics, you’re the reason we do what we do. Here, your story matters, and we don’t try to squeeze it into a checklist of concerns. Our deeply personalized approach doesn’t just ensure you love your results, but also that you enjoy the journey.


An Approach That Empowers
Confidence starts with clarity, which is why your journey at Aion starts with a private consultation. This visit isn’t a sales pitch—it’s a time for you to open up about your struggles and aspirations in a safe environment. Rather than simply asking what treatments you want, we ask you how you want to feel.
Once we truly understand what brought you to our medspa in the Upper East Side, NYC, we work together to craft a plan to accomplish your goals. We don’t upsell, over-promise, or speak over your head. Instead, we act as your partner, treating you with the respect you deserve.
When you walk out of our office after your consultation, you’ll leave feeling empowered. Dr. Akis walks you through why we recommend the treatments we do, so you feel confident beginning your journey. People stay with us for years because they know they always have a voice in their care, and that voice matters. Your journey is about becoming the best version of yourself on your terms, not anyone else’s.
A Standard of Precision
There’s power in feeling understood, but executing your vision requires an entirely different skill set. At our med spa, Upper East Siders don’t have to choose between warmth and expertise. We offer the most advanced services in a professional yet comfortable setting, providing the clinical and emotional support you need along your journey.
When you choose Aion Aesthetics as your partner, you’re not just investing in a treatment—you’re investing in a standard. Ours just happens to be the highest.
Named Top Aesthetic Injectors for several consecutive years, Dr. Akis Ntonos, DNP, leads our team to pursue excellence. Having trained alongside Industry-leading medical providers in the U.S., Europe, and Asia, Dr. Akis is recognized for his expertise. He continues to expand and share his knowledge, both with our team and providers across the nation.
Why? Because the wellness and aesthetic world revolves around trends, but it should revolve around evidence. We don’t simply offer treatments because they’re popular but because they’re proven, and we’ve mastered how to tailor your experience to deliver the most meaningful results.
A Partnership Without an Expiration Date
As your habits, struggles, and goals evolve, your provider’s approach shouldn’t stay stuck in the past. As a leading med spa in the Upper East Side, NYC, Aion Aesthetics welcomes change. Change is a sign of growth, and rather than dismissing your evolving needs, we work to understand them, making intentional changes to our approach.
Of course, we want you to walk out of our office feeling incredible every time, but we’re more interested in your long-term success than immediate gratification. We’re here to help you write every chapter of your story, from preparing to walk down the aisle to stepping into parenthood and beyond.
We don’t just support you during your treatments but throughout your beautiful evolution. Our job isn’t done once you’re happy with your results. We follow up. We adjust. We prioritize what matters to you, because when you envision the best version of yourself today, it doesn’t look the same as your vision 5 years ago—or in the future.
It’s Time to Put Yourself First
When you choose Aion, you choose yourself. People tend to overlook their relationship with themselves, despite it being the most important one they have.
Investing in yourself in a world that demands so much isn’t selfish or vain. Feeling truly beautiful in your skin allows you to show up for yourself and others fully. It is an act of generosity that benefits the most important people in your life just as much as it benefits you.
This is about strength, not indulgence. You gain more than healthier skin or fuller hair when you come to our med spa. Upper East Siders and people from across the world come to us to gain strength, reconnecting with themselves so they can connect with everyone and everything on a deeper, more meaningful level.
