You're Probably Using the Wrong Type of Light Therapy
Most people discover light therapy and immediately buy a red light panel.
Then they wonder why they're not getting the full result.
Here's the thing: red light, near-infrared, and UVB are three completely different tools. Using only one is like having a full gym but only ever using one machine.
This guide breaks down exactly how each one works.
Why Your Body Responds to Light at All
Your body didn't evolve under fluorescent bulbs.
For thousands of years, it received specific wavelengths of light at specific times of day. Morning light. Midday UVB. Evening red and infrared.
Each wavelength does something different. And modern indoor life has quietly removed most of them.
That's the gap most wellness routines never address.
The 3 Types of Light Therapy
1. Red Light (620–700nm)
Red light is visible, you can see it with your naked eye.
It penetrates the outer layers of skin and has been extensively studied for its interaction with mitochondria, specifically a protein called cytochrome c oxidase, which plays a role in cellular energy production.
Research has explored red light in relation to skin appearance, post-exercise recovery support, and general cellular function.
Best used: Morning to early afternoon, 10–20 minutes at manufacturer-recommended distance.
2. Near-Infrared (NIR)
Near-infrared is invisible, but you may feel mild warmth.
It penetrates deeper than red light, past the skin surface and into muscle tissue. Because of this, it's been studied in the context of recovery and deep tissue support.
Best used: Post-workout or evening. Unlike blue light, NIR doesn't appear to interfere with natural sleep patterns.
3. UVB
This is the one most people overlook. And it might be the most important.
UVB is the wavelength responsible for initiating vitamin D synthesis in the skin, the same photochemical process your body uses when you're outdoors in sunlight.
The problem? Most people today get almost none of it.
If you work indoors, live at a northern latitude, or regularly use broad-spectrum sunscreen, you may be going weeks — or months — without any meaningful UVB exposure.
Best used: Midday window, mirroring the natural UVB peak. Session duration varies by skin type, always follow your device's guidelines carefully.
⚠️ UVB exposure should always follow device instructions. Consult a healthcare provider before use if you have skin sensitivity or take medications that affect UV response.
The Most Common Mistake in Light Therapy
People assume red light does everything.
It doesn't.
Red light won't initiate vitamin D synthesis. That's a UVB function — full stop. This is the most common misconception in the space, and it's why a lot of people run a solid red light protocol for months and still feel like something's missing.
They're not wrong. Something is missing.
How to Use All Three Together
These wavelengths aren't competing, they're designed to work at different times of day.
In the morning, UVB or outdoor natural light supports the body's natural vitamin D synthesis process. Mid-morning is a great window for red light as part of a skin and cellular wellness routine. In the evening, near-infrared supports recovery without disrupting natural sleep patterns the way blue light does.
This mirrors the varied light inputs your body was built to receive, adapted for a life mostly lived indoors.
What to Look for in a Device
Not all light therapy devices are built the same. Here's what separates a well-engineered device from an expensive lamp.
For red light and NIR panels, look for published irradiance data. Dual wavelength output (660nm + 850nm) gives you both red and near-infrared coverage in one session. Low EMF emissions matter for something you use daily at close range.
For UVB lamps, the device should clearly specify its output range and recommended exposure protocol, with guidelines that vary by skin type. Look for devices designed for personal home use, not repurposed tanning or grow equipment.
The Mitolux Approach
We built Mitolux around a simple question: what does your body actually need from light and how do we deliver it with precision?
Our devices are engineered to support the skin's natural vitamin D synthesis process, through UVB and deliver verified wavelengths at real irradiance levels, with low EMF output and published specifications.
FAQ
Can I use red light and a UVB lamp on the same day? Yes. They work through different mechanisms and don't interfere with each other. Many people use both as part of a daily routine at different times. Always follow each device's guidelines, and consult a healthcare provider if you have any underlying health conditions.
Does red light therapy produce vitamin D? No. Only UVB wavelengths initiate the photochemical process that produces vitamin D in the skin. Red light doesn't trigger this reaction — this is one of the most common misconceptions in the space.
Is near-infrared the same as red light? Related, but distinct. NIR and red light are often delivered by the same panel, but they penetrate tissue to different depths. Most quality devices combine both.
How do I know if my device is actually working? Look for verified irradiance data (mW/cm²) at your usage distance. Devices that publish third-party tested specs give you a real benchmark. Individual results vary with consistent use.
