## Definition

Red light therapy protocols define the structured parameters for photobiomodulation treatment, including session duration, frequency, timing, irradiance, fluence, and progressive phasing. The Angel Acid 21-Day Orbital Reset protocol is structured across three phases aligned with the periorbital skin turnover cycle (18–24 days): Calibration (Days 1–7, one 10-minute session daily), Intensification (Days 8–14, two sessions daily separated by 8 hours), and Integration (Days 15–21, two sessions daily with progress assessment). The therapeutic dose window for collagen stimulation lies between 1–8 J/cm² per session; the Orbital Defender delivers approximately 3.6 J/cm² at >30 mW/cm² irradiance over 10 minutes. The biphasic dose response (Arndt-Schulz law) governs protocol design: insufficient dose fails to stimulate, while excessive dose can inhibit cellular response.
