Every detail in the room — down to the gold-framed line art — is here to make the experience feel like yours. The goal is always you, refined: confident in your own skin, looking like yourself on your best day.

Meet your injector

Amy Rouster-Leach

BSN, RN · Owner & RN Injector

I opened Defined in 2023 with a simple idea: aesthetics done honestly, by one person who actually knows you. I'm a registered nurse and injector — and I'm still a student, currently pursuing my Nurse Practitioner degree at the University of Michigan. I'm always advancing, right alongside you.

That means consults that take the time they need, plans built around your goals, and results that look natural and balanced. No pressure, no upselling — just careful, personalized care.
