Red light boosts collagen and reduces redness in the skin.Red Light Therapy (RLT), also known as Low-Level Laser Therapy (LLLT) or Photobiomodulation, is becoming one of the most effective at-home tools for women struggling with:
- Low thyroid function
- Slow metabolism
- Fatigue
- Dry or aging skin
- Collagen loss
- Inflammation
- Redness or rosacea
- Hormonal acne
Unlike heat-based devices, red + near-infrared light enters cells and boosts mitochondrial energy, improving both thyroid function and skin repair.
Let’s break it down simply.
⭐ How Red Light Therapy Works (Simple Explanation)
Red (630–660 nm) and near-infrared (810–850 nm) wavelengths:
- Increase ATP (cell energy)
- Reduce inflammation
- Support thyroid hormone production
- Improve collagen synthesis
- Increase blood circulation
- Calm mast cell activation
- Support skin barrier repair
This combination is why RLT improves both thyroid health and skin appearance at the same time.

1. Increases T4 → T3 Conversion
The thyroid relies on mitochondria.
More cellular energy = better hormone activation.
