Brilyn Jacobsen, Founder, FNP
Born and raised in California’s Central Valley, Brilyn's journey into medicine began with a deep-rooted passion for wellness and women’s health. She earned her Bachelor’s Degree in Chemistry and Biology from New Mexico State University, where she also studied under a midwife, working hands-on in holistic women’s care.
Before entering the aesthetics field, Brilyn served as a medical researcher contributing to groundbreaking work on the Ebola outbreak — an experience that shaped her scientific rigor and dedication to care. Upon returning to California, she followed her calling into nursing and found her true passion in aesthetic medicine.
With over a decade of experience as a cosmetic injector and skincare specialist, Brilyn is known for her gentle approach, her focus on natural, preventative results, and her commitment to personalized care. She believes aesthetics is about more than beauty — it’s about confidence, vitality, and helping each client feel like the best version of themselves.
A proud mother of two, Brilyn finds balance through gardening, hiking, skiing, and tennis — usually with her two schnauzers not far behind.

Mackenzie’s journey into women’s health began over a decade ago with a career in esthetics, where she developed a deep appreciation for the connection between gut health, hormone balance, and glowing skin. After three years in skincare, her desire to make a broader impact inspired her to pursue nursing and medical training.
As a Registered Nurse, Mackenzie has served in Labor & Delivery and Emergency Medicine, and most recently worked alongside a functional medicine physician in the Central Valley.
