Meet the Team

Founder | Biological Esthetics & Regenerative Skin Specialist 

Ambershea is the founder of The Joshua Tree Spa and a Licensed Master Esthetician specializing in Biological Esthetics—an advanced approach to skin health that works with the body’s natural systems to restore function, balance, and long-term vitality.

With extensive training in advanced skin therapies, she holds certifications as a Skin Revision Therapist, Master Acne Specialist, Certified Laser Technician, and MD Paramedical Therapist, along with expertise in microneedling, chemical peels, and corrective skin treatments.

Her work goes beyond traditional skincare by addressing the deeper connections between the skin, nervous system, metabolism, and cellular health. Through a biohacking-informed lens, Ambershea creates treatment experiences that support the body’s ability to repair, regulate, and regenerate from the inside out.

Rooted in the principles of circadian rhythm, light biology, and nervous system regulation, her approach focuses on restoring optimal function—allowing the skin to become stronger, more resilient, and visibly healthier over time.

“My journey with skin health is personal. I believe radiant skin is not created—it’s expressed when the body is supported at a cellular level.”

Known for her results-driven work with DMK Enzyme Therapy, Ambershea combines science, nature, and a systems-based understanding of the body to guide clients toward lasting transformation—far beyond surface-level results.

Her mission is to redefine skin health through Biological Esthetics—where true results come from working with the body, not against it.
