Dr. Stephanie Rimka
With nearly three decades as a clinician, educator, and speaker, I specialize in brain health, nervous system regulation, and complex chronic conditions. As a founding faculty member of Peptide University, I train clinicians globally in peptide therapies and advanced interventions focused on mitochondrial function, cellular signaling, and clinical sequencing.
Early in my career, treating children with autism, ADHD, anxiety, and dyslexia revealed a clear pattern: behind every struggling child was a depleted, dysregulated mother. This insight shifted my focus to women’s health. Moving beyond superficial symptom management, I use a systems-based physiological approach to help women restore energy, stabilize their nervous systems, rebuild metabolic and mitochondrial capacity, and sustainably reconnect with their bodies.
Bridging neuroscience, trauma physiology, and bioenergetics, I challenge reductionist models with evidence-based, precision medicine. I am also the author of Receive: The Dance of Feminine Power, exploring the intersection of biology, embodiment, and feminine intelligence in healing.

Frequently Asked Questions
Questions before you gofull-spectrum?
At a distance of 12–31 inches, we recommend 5–10 minutes per session.
Where you land in that range depends on two things: how deep the target tissue sits, and what's in front of it.
Light has to travel through whatever sits between the panel and the tissue you're treating. A knee joint is surrounded by dense bone and connective tissue, so it needs more exposure time and higher intensity to reach the target. Facial skin sits right at the surface and needs far less. Deeper or more obstructed target, longer session. Surface tissue, shorter session.
Important: never use COB mode on facial skin.
Facial skin is the most sensitive skin on your body and responds differently to high-intensity light than skin anywhere else. For any direct facial application, use LED mode only, at a minimum distance of 24 inches.
This isn't a comfort recommendation — it's how the device is meant to be used. COB mode is for body tissue: joints, muscles, back, and deeper targets.
Quick reference
Target Mode Distance Time
Face and surface skin LED only 24 inches minimum 5 minutes
Muscle and soft tissue COB or LED 12–31 inches 5–10 minutes
Joints and deep tissue COB 12–31 inches 10 minutes
No. Our lamps are designed with low-EMF output and shielded internal wiring to ensure user safety.
Nearly all lights including incandescent flicker from being powered by AC power.
LEDs can be particularly troublesome if they are designed with low quality components.
Our lights use high quality power drivers to ensure practically no flicker, please read our blog on "the flicker effect" where we show flicker vs very limited flicker. We have eliminated the flicker to the point where even in slow motion video it can not be detected.
We recommend closing your eyes during facial exposure. For prolonged or very close facial use, wearing goggles is advised.
