The science

The science of red light

A simple, non-invasive ritual that works with your body, not against it — using specific wavelengths of red and near-infrared light to support your skin, recovery, and overall wellbeing.

How red light therapy works

How red light therapy works

Your skin is always working behind the scenes. It repairs, renews, and responds to everything from stress and sleep to skincare and sunlight.

Red light therapy is designed to support that natural process using specific wavelengths of red and near-infrared light.

Unlike UV light, red and near-infrared light do not tan or burn the skin. Instead, they gently reach the skin and underlying tissue, where they are believed to interact with the mitochondria — the tiny energy centers inside your cells.

This process is known as photobiomodulation: light used to encourage a natural cellular response.

The basics

What is red light therapy?

Red light therapy is a gentle treatment that uses targeted wavelengths of light to support skin health, recovery, and overall wellness.

During a session, you place the device near your skin and let the light do its work for a set amount of time. There is no heat, no needles, no downtime, and nothing complicated to figure out.

With consistent use, it may help support a brighter-looking complexion, smoother skin texture, and the appearance of healthy, well-rested skin.

Wavelengths

Red vs. near-infrared

Red light and near-infrared light are often used together, but they are not exactly the same.

Red vs. near-infrared

Our devices combine seven targeted wavelengths so light can support your skin and body at multiple depths, from the surface down to deeper tissue.

Visible red light (590, 630, 660 nm) works mainly on the surface layers of the skin — typically used to support skin tone, texture, radiance, and the appearance of fine lines.

Near-infrared light (810, 830, 850, 940 nm) is not visible to the eye and reaches deeper into the body, where it is often used to support recovery, comfort, circulation, and deeper cellular activity.

Know your light

Red light vs. near-infrared

Two kinds of light, two different jobs. Pick your goal and see which one fits.

What matters most to you?
Red light
  • Visible — the warm red glow you can see
  • 630–660 nm wavelengths
  • Works nearer the skin’s surface
  • Commonly used for skin tone, texture, radiance and the appearance of fine lines
Near-infrared
  • Usually invisible — working even when you can’t see it
  • 810–850 nm wavelengths
  • Reaches deeper tissue
  • Commonly used for muscle recovery, joint comfort and deeper body support

Both work with your cells’ natural energy response — and they work well together. Every BioRed panel and the Belt combine the two. Read the full guide →

The key idea

Light is not just something you see. It is energy your cells can respond to.

The routine

Why consistency matters

Red light therapy is not about one dramatic before-and-after moment. It works best when it becomes part of your routine.

Each session gives your skin and cells a gentle dose of supportive light energy. Over time, that consistency may help encourage the natural processes your body is already built to do.

Think of it like skincare, hydration, or movement — the results come from showing up regularly.

What to expect

What you may notice

Red and near-infrared light are absorbed by your cells, where they're thought to support natural energy production and repair. Here's where people most often notice a difference.

Skin & beauty

Skin & beauty

Used consistently, red light may help support a brighter, smoother-looking complexion, a more even-looking tone, and the appearance of fewer fine lines. It's also a popular at-home way to support fuller-looking hair.

Recovery & comfort

Recovery & comfort

Many people use red and near-infrared light after exercise to support muscle recovery and ease everyday aches — a gentle, complementary part of a wellness routine.

Body & circulation

Body & circulation

Red and near-infrared light may help support healthy circulation and comfort in the areas you treat. Some people also use it as a supportive part of a body-care routine, alongside regular movement and a balanced diet.

For your pets

For your pets

Red light therapy isn't just for people. It's increasingly used to support comfort, mobility, and recovery in dogs and cats — a gentle addition to your pet's everyday care.

How a session works

Four simple steps

1

Position

Place your device on a stable surface and sit or stand at the recommended distance, with the light directed toward the area you want to target.

2

Treat

Start your session and relax while the light does its work. Most routines take just a few minutes, making it easy to fit into your day.

3

Repeat

Use your device consistently. Like skincare or movement, red light therapy works best when it becomes part of your regular routine.

4

Track

Pay attention to how your skin and body feel over time. Small changes can build gradually with regular use.

FAQ

Common questions

Is red light therapy safe?

Yes. For most people it's gentle, non-invasive, and easy to use when you follow the device instructions. BioRed Light devices do not use UV light, so they are not designed to tan or burn the skin.

Start with the recommended session time, use the included protective glasses when provided, and avoid looking directly into the lights. If you have a medical condition, check with your healthcare provider before use.

How often should I use it?

Consistency is key. Most people use red light therapy several times per week. The Mask and panels default to 10-minute sessions (panels up to 30); start the Belt at 10–15 minutes per area and the Laser Cap at 5–10 minutes.

A simple, steady routine works better than long sessions once in a while.

How long until I see results?

Some people notice a relaxed feeling or a fresher-looking glow after the first few sessions. More visible changes usually take more time — think weeks, not days. Results depend on your goals, the device, and how consistent you are.

Which device should I choose?

Choose based on the area you want to target and how much coverage you want.

Max Panel — the most coverage, for full-body routines. Mid-Size Panel — powerful in a compact size, for targeted and half-body sessions. Red Light Mask — for your face. Laser Cap — scalp and hair. Portable Belt — flexible support for sore joints and muscles.
