Skin Rejuvenation / Anti-Aging
Source: Multiple Clinical Trials
Protocol for facial skin rejuvenation targeting fine lines, wrinkles, skin texture, and overall complexion. Red wavelengths (630-660nm) stimulate collagen production in the dermal layer, improving skin elasticity and reducing visible signs of aging.
Protocol Parameters
| Condition | Photoaging / Wrinkles |
| Wavelengths | 630nm, 633nm, 660nm |
| Dosage | 3-6 J/cm² |
| Irradiance | 20-50 mW/cm² |
| Duration | 10-20 minutes |
| Frequency | 3-5x per week, 8-12 week course |
| Body Zone | face |
| Evidence Level | Strong |
Mechanism of Action
Red light upregulates collagen type I and III synthesis in dermal fibroblasts, stimulates procollagen production, reduces MMP (matrix metalloproteinase) activity that breaks down collagen, and enhances cellular repair mechanisms. The net effect is increased dermal thickness, improved elasticity, and reduced wrinkle depth.
