The Science of Light

The Science Behind the Halo Mask

Light therapy, made simple

The LunAura Halo Mask uses specific colors of light to support clearer, smoother and healthier-looking skin. This is called LED light therapy. LED stands for light-emitting diode. The Halo contains 288 LEDs that shine carefully selected wavelengths of blue, red and near-infrared light onto the skin.

Each type of light has a different purpose:

Blue light supports blemish-prone skin.
Red light supports smoother, brighter and firmer-looking skin.
Near-infrared light works beyond what the eye can see to support the skin’s natural renewal and recovery processes.

The Halo brings all four wavelengths together in one hands-free mask, making light therapy easier to use as part of your regular routine.

What is a wavelength?

Light travels in waves. A wavelength tells us what type of light is being used and is measured in nanometers, written as nm. Different wavelengths can reach and interact with the skin in different ways.

The Halo Mask uses four wavelengths:

460 nm blue light
660 nm red light
850 nm near-infrared light
1064 nm near-infrared light

Blue and red light are visible, which means you can see them while using the mask. Near-infrared light is invisible to the human eye, but it can still be active even when you cannot see it glowing.

460 nm Blue Light

For clearer-looking, blemish-prone skin, blue light works mainly near the surface of the skin. One reason blue light is used for acne-prone skin is that it can interact with substances made by Cutibacterium acnes, a type of bacteria linked to inflamed breakouts. This makes blue light most helpful for skin with active, red or irritated-looking blemishes.

Blue light may help support:

A clearer-looking complexion
The appearance of active blemishes
Blemish-related redness
Oily or congested-looking skin
A more balanced-looking complexion

Blue light may not work the same way for every type of acne. Deep cystic acne, hormonal breakouts, blackheads and closed bumps may require other skincare or professional treatment.

660 nm Red Light

For smoother, brighter and firmer-looking skin, red light reaches beyond the very top layer of the skin. It is commonly used in skincare to support the processes connected to skin renewal, collagen and healthy-looking circulation. Collagen is a natural protein that helps skin look firm, smooth and supported. As we age, the skin naturally produces less collagen. Sun exposure, stress and other factors can also affect the skin’s appearance. Consistent red-light use may help support skin that looks refreshed and more radiant.

Red light may help improve the appearance of:

Fine lines
Uneven texture
Dullness
Temporary redness
Loss of firmness
Tired-looking skin
Overall brightness and glow

Red light is not an instant facelift and will not stop the natural aging process. The best results usually come from regular use over time.

850 nm Near-Infrared Light

Invisible support for skin renewal, near-infrared light is often called NIR. The Halo uses 850 nm near-infrared light, which reaches more deeply than visible blue and red light. Even though you cannot see this wavelength, it may still interact with the skin and nearby tissue. Near-infrared light is studied as part of a process called photobiomodulation. This simply means using light to support normal activity inside the body’s cells.

850 nm near-infrared light may help support:

The skin’s natural recovery process
A calmer-looking complexion
Healthy-looking circulation
Skin that appears more resilient
Smoother, refreshed-looking skin
The benefits of a red-light routine

The LEDs may look dim or appear not to be on when near-infrared light is active. That is normal because human eyes cannot see near-infrared light clearly.

1064 nm Near-Infrared Light

A longer wavelength for added support, the Halo also includes 1064 nm near-infrared light. This is a longer wavelength than 850 nm and is included to expand the range of near-infrared light used by the mask. Research on longer near-infrared wavelengths is still growing. For that reason, we do not claim that 1064 nm treats medical conditions or produces one exact result. It is included to complement the red and 850 nm near-infrared wavelengths in the Halo’s light therapy system.

1064 nm is designed to:

Add another near-infrared wavelength to the routine
Complement 660 nm red and 850 nm near-infrared light
Support a more complete light therapy experience
Expand the range of light delivered by the Halo

Why does Halo use four wavelengths?

Skin needs can change. Some days, your main goal may be supporting blemish-prone skin. At other times, you may be focused on brightness, texture, firmness or recovery. Each Halo wavelength has its own role:

Blue light helps clarify

The 460 nm blue light supports blemish-prone skin and a clearer-looking complexion.

Red light helps renew

The 660 nm red light supports smoother, brighter and firmer-looking skin.

Near-infrared light helps restore

The 850 nm and 1064 nm wavelengths work beyond the visible light spectrum to support the skin’s natural renewal and recovery processes.

Together, these wavelengths allow the Halo to support several common skin goals in one device.

How light works with your cells

Your skin is made of cells. These cells need energy to perform their normal jobs. Inside many cells are tiny structures called mitochondria. You can think of mitochondria as the cell’s energy centers. Scientists believe that red and near-infrared light can interact with light-sensitive parts of the cells. This may influence how cells create and use energy and how they communicate during normal renewal and recovery. This process is called photobiomodulation. In simple terms, the light does not peel, scrape or damage the skin. It is used to gently support the skin’s natural processes. Researchers are still studying exactly how these changes happen, and results can vary from one person to another.

What does irradiance mean?

The Halo’s specification sheet lists an irradiance of 50 mW/cm². Irradiance describes how much light power reaches a certain area of the skin at one time. However, the strength of the light is only one part of an LED treatment. The total amount of light received also depends on:

How long the session lasts
How close the LEDs are to the skin
Which light mode is selected
How often the mask is used
How evenly the mask fits across the face

More light is not always better. Using the mask longer or more often than directed does not guarantee faster results and may increase the chance of irritation.

Always follow the recommended treatment time in the Halo instructions.

Why consistency matters

LED light therapy works best as a routine, not as a one-time treatment. One session may leave the skin looking refreshed, but visible changes in blemishes, texture, fine lines or firmness usually take repeated use.

Your experience may depend on:

Your skin type
Your starting skin concerns
The mode you use
How often you use the mask
Your skincare routine
Hormones
Stress and sleep
Sun exposure
Medications
Existing skin conditions

Some people may notice brightness or a calmer appearance sooner. Other goals may take several weeks of consistent use. The Halo was created to make consistency easier by turning light therapy into a simple, hands-free ritual.

How to use Halo with skincare

For the clearest light exposure, begin with clean, dry skin unless your healthcare provider has told you otherwise. A simple routine may look like this:

Gently cleanse and dry your face.
Put on the Halo Mask.
Select the light mode that matches your skin goal.
Complete the recommended session.
Apply your usual serum, moisturizer or other skincare afterward.
Wear broad-spectrum sunscreen during the day.

Thick or opaque products may block some light from reaching the skin. This is why using the mask before applying heavier skincare products may be helpful. LED therapy should support your skincare routine, not replace gentle cleansing, hydration or sunscreen.

Is LED light the same as UV light?

No.The blue, red and near-infrared wavelengths used by Halo are different from ultraviolet light. Halo is not designed to tan the skin, and it does not work by intentionally burning or damaging the skin. You should still wear sunscreen every day because LED light therapy does not protect your skin from sunlight or UV exposure.

Is near-infrared light supposed to be invisible?

Yes. Both 850 nm and 1064 nm are near-infrared wavelengths. They sit outside the range of light that human eyes can clearly see. This means the near-infrared LEDs may appear dim or may not look illuminated even when they are operating. Invisible does not mean inactive.

Is stronger light always better?

No. Effective light therapy depends on the right balance of wavelength, strength, treatment time and frequency. Using the mask longer than instructed does not mean you will get better or faster results. Follow the Halo directions and give your skin time to respond. Consistency is more important than overusing the device.

Who should ask a professional before using Halo?

Speak with a qualified healthcare professional before using the mask if you:

Take medication that can increase light sensitivity

Use prescription treatments that make your skin sensitive

Have a light-sensitivity condition

Have epilepsy or light-triggered seizures

Have significant eye disease

Are being treated for cancer

Have an unexplained or active skin condition

Recently had a procedure that left your skin very sensitive

Are unsure whether LED therapy is right for you:

Stop using the mask if you experience lasting pain, unusual irritation, worsening redness, changes in vision or another unexpected reaction.

Severe, painful, cystic, scarring or long-lasting acne should be discussed with a dermatologist.
