Clinical careers first, aesthetics second
Lumiere Laser Med Spa was built around clinical judgment, thoughtful treatment planning, and devices selected because specialists actually recommend them.
Our philosophy
That was deliberate. Aesthetic medicine has a trust problem, and it is usually earned. Injectors with weekend certifications. Devices bought because they were cheap, not because they worked. Consultations that feel like sales calls. We built Lumiere to be the answer to that, which meant starting with the team rather than the storefront.
Our medical director came from board-certified emergency medicine, with more than twenty years of clinical judgment before he ever touched an aesthetic device. Our physician assistants trained in surgical residencies and hospital emergency departments before specializing in skin.
The result is a practice that looks unassuming from the outside and performs like the ones you’d expect to find on Fifth Avenue. We are comfortable with that trade.

Technology standards
We were selective about our two flagship devices for one reason: almost everything else on the market locally is a step behind. Thermage and Potenza represent a different tier of technology, and they are currently exclusive to Lumiere in this area.
Thermage
Thermage uses radiofrequency energy to heat the deeper layers of the skin, encouraging the body’s own collagen to tighten and remodel over time.
Potenza
Korean-engineered radiofrequency microneedling with energy delivered at different depths depending on what the skin actually needs.
