Acne Treatment Protocol
Source: Clinical Research / Dermatology Guidelines
Protocol for inflammatory acne using blue light (415nm) for antimicrobial action against P. acnes bacteria combined with red light (633/660nm) for anti-inflammatory effects and healing promotion. The dual-wavelength approach addresses both bacterial load and inflammatory response.
Protocol Parameters
| Condition | Acne Vulgaris |
| Wavelengths | 415nm, 633nm, 660nm |
| Dosage | 2-4 J/cm² |
| Irradiance | 20-50 mW/cm² |
| Duration | 10-20 minutes |
| Frequency | 3x per week for 8-12 weeks |
| Body Zone | face |
| Evidence Level | Moderate |
Mechanism of Action
Blue light (415nm) activates porphyrins produced by P. acnes bacteria, generating reactive oxygen species that kill the bacteria. Red light (633-660nm) reduces the inflammatory response, promotes tissue repair, and decreases sebaceous gland inflammation. Together, they address the two primary pathological mechanisms of acne.

Treatment Tips
- *Blue + red combination is more effective than either alone
- *Clean skin thoroughly before treatment
