How Red Light Therapy Works
Red light therapy, also known as photobiomodulation, uses specific wavelengths of visible red and near-infrared light to support the skin’s natural renewal process. Unlike UV light, red light therapy is non-invasive and does not damage the skin barrier. Research suggests that certain wavelengths may help support collagen production, improve the appearance of fine lines, and promote healthier-looking skin over time.

The Science Behind Red Light Therapy
Red light therapy works by delivering concentrated wavelengths of light into the skin at different depths. These wavelengths interact with the mitochondria — often referred to as the “powerhouse” of the cell — helping support cellular energy production known as ATP. Increased cellular energy may help support skin repair, collagen synthesis, and overall skin vitality.
Common Therapeutic Wavelengths
630nm Red Light
Supports surface-level skin rejuvenation and helps improve the appearance of:
Fine lines
Uneven skin tone
Skin texture
Dullness
Research has shown wavelengths in the 630–660nm range are commonly associated with collagen support and visible skin rejuvenation benefits.
660nm Deep Red Light
Penetrates deeper into the dermis to support:
Skin firmness
Elasticity
Collagen production
Smoother-looking skin
Clinical studies have explored 660nm light for its photobiomodulation effects and its role in supporting healthier-looking skin appearance.
810–850nm Near-Infrared Light
Near-infrared light penetrates deeper beneath the skin’s surface and is commonly used to support:
Circulation
Recovery
Skin vitality
Deeper tissue support
Studies suggest near-infrared wavelengths may complement visible red light by reaching deeper layers of tissue.
Why Consistency Matters
Visible skincare improvements from red light therapy are typically gradual and cumulative. Most clinical studies evaluating skin appearance improvements involve consistent treatments over multiple weeks.
For best results:
Use consistently several times per week
Maintain a regular skincare routine
Allow time for gradual skin renewal
Red Light Therapy & Collagen Support
Collagen is a naturally occurring protein responsible for skin firmness and elasticity. As collagen production slows with age, the appearance of fine lines and sagging skin can become more noticeable.
Research suggests red and near-infrared light may help stimulate fibroblasts — the cells responsible for collagen production — helping support firmer, healthier-looking skin over time.
Simplified Process
Light penetrates the skin
Cells absorb therapeutic wavelengths
Mitochondria produce more cellular energy (ATP)
Fibroblasts become more active
Collagen and elastin support increases over time
What Red Light Therapy May Help Improve
Based on published clinical research, red light therapy devices are commonly used to help improve the appearance of:
- Fine lines and wrinkles
- Skin texture
- Uneven tone
- Redness
- Dullness
- Mild inflammatory acne
- Overall skin radiance
Results vary depending on the device, consistency of use, skin type, and individual response.
Non-Invasive Skincare Technology
Red light therapy is widely used because it is:
Non-invasive
Painless
Requires no downtime
Suitable for at-home skincare routines
Compatible with many skincare regimens
Modern LED devices use targeted wavelengths designed to deliver light safely and effectively without UV exposure.
Science-Backed Light Therapy
Emerging research in photobiomodulation continues to explore how red and near-infrared light may support skin health, recovery, and overall wellness. Multiple peer-reviewed studies have evaluated wavelengths commonly used in modern LED skincare devices, particularly within the 630–850nm range.
