Our Philosophy: Helping you create your own definition of beauty
We don’t believe in aggressive sales tactics or cookie-cutter treatments. Our goal is simple: to educate, treat, and empower our patients so they feel confident in their skin—both inside and out. Whether you’re coming in for preventative care, addressing specific skin concerns, or looking for an advanced treatment plan, we’re here to guide you with honesty, expertise, and the highest standard of care.
At Define Beauty Medspa, you won’t just see results—you’ll feel them. Your journey to healthy, beautiful skin starts here.

Our Story
McKenzie’s journey in aesthetics began at 18 when she moved to Arizona from a small town in Illinois with the dream of creating something unique in the skincare industry. Over the years, she gained hands-on experience in fast-paced corporate medspa, high-end aesthetic clinics, and dermatology offices, learning firsthand what worked—and what didn’t—when it came to patient care.
She founded Define Beauty Medspa to create a space where patients feel genuinely heard, valued, and cared for. Unlike many large medspas where providers come and go, Define Beauty Medspa prioritizes long-term relationships, ensuring consistency, trust, and superior results.
