Red Light Therapy Explained
What Exactly Is Red Light Therapy?
Red light therapy uses low wavelength red light (typically 630 to 660 nm) and near infrared light (810 to 850 nm) to stimulate cellular repair. Instead of heating the skin or causing damage like lasers or peels, it works at a deeper level, improving how your cells create energy. Think of it as giving your body more power to regenerate, repair, and function better.

The Real Benefits You Can Expect
The research on red and near infrared light has grown fast in the last decade. Here are some of the most supported benefits.
Improved skin texture and glow
Red light boosts collagen production, which helps soften fine lines, even out tone, and create that subtle “lit from within” look.
Reduced inflammation
It helps calm irritated skin, post workout soreness, joint pain, and general inflammation. Many people notice faster recovery and less stiffness.
Better cellular energy
Because it influences mitochondria, you may feel a small but measurable boost in energy, mood, and overall well being.
Support for wound healing and scarring
Studies show red light can speed up recovery from cuts, burns, scars, and post procedure healing.
Hair growth support
Low level red light can stimulate follicles, helping improve thickness and reduce shedding for some people.
Is It Safe?
For most people, yes. Red light therapy is considered safe and non invasive, with no downtime. The light does not burn or damage the skin, and side effects are extremely rare. It’s still smart to avoid shining it directly into your eyes and to check with a doctor if you’re pregnant, have active cancer, or take photosensitive medications.
How Often Should You Use It?
The magic of red light therapy is consistency. The effects are cumulative, not instant. A good starting point is:
Three to five sessions per week
Ten to fifteen minutes per session
Roughly six to eight inches away from the device
Most people notice visible improvements within four to eight weeks.
Should You Add It to Your Routine?
If your goals include glowing skin, better recovery, improved mood, or simply supporting your body at a cellular level, red light therapy is genuinely worth exploring. It’s gentle, accessible, and works alongside everything else you’re already doing for wellness.
And like anything that creates real change, it rewards commitment. A few minutes of red light, consistently applied, can become one of those small habits that make a surprisingly big difference.
