Red light therapy (RLT) is gaining popularity as a non-invasive way to improve skin health, reduce pain, and promote healing. Used by athletes, dermatologists, and wellness enthusiasts, this treatment involves exposing the body to low-wavelength red or near-infrared light, which penetrates the skin to stimulate cellular repair and function. But is it safe? And which type of red light therapy is best? Let’s explore.
How Red Light Therapy Works
Red light therapy works by delivering wavelengths between 600 and 1000 nanometers (nm) to the skin. These wavelengths penetrate deep into the cells, enhancing energy production in the mitochondria. This can lead to increased blood circulation, reduced inflammation, and faster healing.
Is Red Light Therapy Safe?
Yes, when used correctly. Unlike UV light from the sun or tanning beds, red light therapy does not contain harmful radiation that damages the skin. The FDA has approved certain RLT devices for therapeutic use, making it a relatively low-risk treatment.
Possible Side Effects:
- Mild skin irritation or redness
- Temporary eye strain (if exposed without proper protection)
- Overuse can cause dryness or sensitivity
To avoid side effects, always follow manufacturer guidelines and wear protective eyewear when using near-infrared light.
Best Types of Red Light Therapy Devices
Not all red light therapy devices are created equal. Here’s what to look for:
- Wavelength Matters – The most effective wavelengths are:
- 630–660 nm (Visible Red Light): Best for skin health, collagen production, and anti-aging.
- 810–850 nm (Near-Infrared Light): Best for muscle recovery, deeper tissue healing, and pain relief.
- Power Density – Measured in milliwatts per square centimeter (mW/cm²), this determines how much light energy reaches the skin. Look for devices with at least 30-100 mW/cm² at a close range.
- Type of Device:
- Panels (For Full-Body Therapy): Great for professional-level treatment at home.
- Handheld Devices (For Spot Treatment): Ideal for targeting small areas, such as joints or acne-prone skin.
- Bulbs (For DIY Use): Can be placed in standard light fixtures, but ensure they emit the right wavelength.
Recommended Brands: Joovv, Mito Red Light, PlatinumLED, and GembaRed.
How to Use Red Light Therapy
- Frequency: 3-5 times per week, for 10-20 minutes per session.
- Distance: Keep the light 6-12 inches from your skin for best results.
- Duration: Start with 10 minutes per area and increase as needed.
- Consistency: Results take time—most people notice changes in 4-8 weeks.
Pros and Cons of Red Light Therapy
Pros:
✔️ Non-invasive and painless
✔️ Can reduce wrinkles, scars, and acne
✔️ Helps with muscle recovery and joint pain
✔️ May improve sleep and reduce stress
✔️ Can be used at home with the right equipment
Cons:
❌ Requires consistent use for noticeable results
❌ High-quality devices can be expensive
❌ Overuse may cause skin sensitivity
❌ Not a cure-all; best used as part of a broader health routine
Final Verdict
Red light therapy is a promising wellness tool with multiple benefits, from skin rejuvenation to pain relief. When choosing a device, focus on the right wavelength, power density, and quality. While safe for most people, it’s best to consult with a healthcare provider if you have sensitive skin or medical conditions.
