Collagen is the most abundant protein in your body and the foundation of youthful skin. Red light therapy is one of the most effective ways to boost collagen production.

What is Collagen?

Collagen provides structure to:

  • Skin (firmness and elasticity)
  • Bones (strength and density)
  • Joints (cartilage and connective tissue)
  • Blood vessels (flexibility and integrity)

Collagen production declines ~1% per year after age 25. By age 50, you’ve lost ~25% of your collagen.

How RLT Boosts Collagen

Mechanism

  1. Stimulates fibroblasts — The cells that produce collagen
  2. Increases ATP production — More energy for collagen synthesis
  3. Activates TGF-β — Growth factor that promotes collagen production
  4. Reduces MMPs — Enzymes that break down collagen

Clinical Evidence

2014 Study (Photomedicine and Laser Surgery):

  • Red light therapy for 30 sessions
  • Significantly increased collagen density
  • Improved skin texture and firmness

2013 Study (Journal of Cosmetic and Laser Therapy):

  • Increased collagen production by up to 200%
  • Improved skin thickness and elasticity
  • Visible reduction in fine lines

Treatment Protocol

Parameter Recommendation
Wavelength 660nm (red light)
Duration 10-15 minutes
Frequency Daily
Distance 6-12 inches
Timeline 8-12 weeks for visible improvement

Best Practices

  1. Consistency is key — Daily use for maximum collagen stimulation
  2. Clean skin first — Better light penetration
  3. Combine with vitamin C — Essential cofactor for collagen synthesis
  4. Protect from UV — Sun breaks down collagen
  5. Consider collagen supplements — Provide building blocks for new collagen
