About
Our Approach
House of Onyx MedSpa is a private aesthetic studio in Vienna, Virginia, designed for clients who value subtle, intentional results.
Care is grounded in precision, restraint, and long-term outcomes. We prioritize structure, skin integrity, and natural balance over trends or overcorrection.
Appointments are unhurried and entirely one-on-one, allowing for focused care, discretion, and a level of clinical judgment that’s rarely found in high-volume environments.
Every treatment plan is tailored, with an emphasis on education, consistency, and results that evolve over time.
