LED Light Therapy Colours Explained: Red, Blue and Near-Infrared Benefits for Your Skin
LED face masks may look futuristic, but the idea behind them is surprisingly simple: different wavelengths of light interact with the skin in different ways.
Red light is often associated with smoother, firmer-looking skin. Blue light is commonly used in routines for blemish-prone skin. Near-infrared light works beyond the visible spectrum and is often paired with red light to support skin renewal and an overall healthier-looking complexion.
But what do those colours really mean—and which one should you use?
This guide explains the three wavelengths found in the Me Time Ritual Wireless LED Mask PRO: red light at 630 nm, blue light at 460–470 nm and near-infrared light at 850 nm.
The quick answer: Choose red mode when your focus is smoothness, firmness and radiance; blue mode when your focus is clearer, more balanced-looking skin; and pink mode when you want a combined routine that supports both clarity and overall skin appearance.
What is LED light therapy?
LED stands for light-emitting diode. An LED skincare device uses specific wavelengths of non-UV light to deliver light energy to the skin.
Wavelength is measured in nanometres, written as nm. It determines the colour of visible light and influences how the light interacts with the skin. Blue wavelengths act closer to the surface, while red and near-infrared wavelengths are associated with activity at progressively deeper levels.
This process is often described as photobiomodulation, particularly when discussing red and near-infrared light. Research suggests that cells can absorb light energy and respond through processes involved in cellular energy, signalling and repair. However, results depend on more than colour alone: wavelength accuracy, irradiance, treatment time, distance from the skin and consistency of use all matter.
LED light therapy is non-invasive and does not use ultraviolet light. It should feel gentle rather than hot or painful.
LED light therapy colour chart
| Light | Wavelength in the Wireless LED Mask PRO | Common cosmetic focus | When to choose it |
|---|---|---|---|
| Red | 630 nm | Smoothness, firmness and radiance | When skin looks dull, tired or less firm |
| Blue | 460–470 nm | Clarity and balance | When skin looks congested, oily or blemish-prone |
| Near-infrared | 850 nm | Skin renewal and overall support | Paired with visible light modes to complement your routine |
| Pink mode | Combination of visible red and blue light | A more comprehensive routine | When you want to support both clarity and overall radiance |
Near-infrared light is invisible to the human eye. This means you will not see the 850 nm wavelength glowing, even when it is operating.
What does red LED light do for the skin?
Red light is the best-known wavelength in at-home LED skincare. It is widely used to support skin that looks smoother, firmer and more radiant.
Research into red and red-to-near-infrared photobiomodulation has reported improvements in measures such as skin roughness, complexion and collagen density after a consistent course of treatment. In one controlled study, participants treated twice weekly experienced improvements in skin feeling, complexion, roughness and measured collagen density compared with controls.
For a cosmetic skincare routine, red light is most relevant when you want to support:
- Smoother-looking skin
- A firmer, more supple appearance
- The appearance of fine lines
- A brighter, healthier-looking complexion
- Skin that looks tired or dull
The Me Time Ritual Wireless LED Mask PRO uses 630 nm red light, a wavelength commonly studied in photobiomodulation and cosmetic skin rejuvenation research.
When should you use red mode?
Choose red mode when your main goal is to support radiance, smoothness and firmness. It can work well as your regular maintenance mode, particularly when your skin is not actively congested.
What does blue LED light do for the skin?
Blue light acts closer to the surface of the skin than red or near-infrared light. It is commonly associated with routines for oily and blemish-prone skin because certain blue wavelengths can interact with porphyrins produced by Cutibacterium acnes, a bacterium associated with acne.
Clinical research has explored blue light both alone and in combination with red light. Some controlled studies using specific blue and red wavelengths have reported improvements in inflammatory and non-inflammatory lesions, oil output and other measures. These studies used their own devices, wavelengths and treatment protocols, so their numerical results should not be assumed for every at-home mask.
In a cosmetic routine, blue light may help support:
- Clearer-looking skin
- A more balanced-looking complexion
- Skin that appears less oily or congested
- A calmer-looking appearance around occasional blemishes
The Wireless LED Mask PRO uses 460–470 nm blue light. Because blue-light effects vary with wavelength and dose, consistency and correct use are important.
When should you use blue mode?
Choose blue mode when your main concern is the appearance of blemishes, congestion or excess oil. Avoid using photosensitising skincare products immediately before your session, and always check the instructions supplied with both your skincare and LED device.
If you have a diagnosed skin condition or persistent acne, seek advice from a qualified healthcare professional. An at-home cosmetic device is not a substitute for medical treatment.
What does near-infrared light do for the skin?
Near-infrared, often shortened to NIR, sits just beyond visible red light on the electromagnetic spectrum. The human eye cannot see it, but suitable devices can still deliver it to the skin.
Near-infrared wavelengths are widely explored alongside red light in photobiomodulation research. They are associated with supporting cellular energy and the skin’s natural renewal processes. Reviews of the clinical literature suggest that red and near-infrared light have promising applications in skin rejuvenation, while also noting that study quality, devices and protocols vary.
The Me Time Ritual Wireless LED Mask PRO uses 850 nm near-infrared light to complement its visible light technology. In cosmetic terms, it is included to support:
- Overall skin renewal
- A smoother and more resilient-looking complexion
- The appearance of firmness
- A healthy-looking glow
Because near-infrared is invisible, do not assume it is inactive simply because you cannot see it.
What is pink LED light?
“Pink light” is not a separate wavelength in the same way that 630 nm red or 850 nm near-infrared is. In the Wireless LED Mask PRO, the pink appearance is created when red and blue visible LEDs operate together.
This combined mode is designed for a more comprehensive routine, supporting both clearer-looking skin and overall radiance. It may be a useful choice when you have more than one visible skin concern or simply want an all-round session.
When should you use pink mode?
Choose pink mode when you want to combine the visible benefits of red and blue light in one session—for example, when your skin looks both dull and blemish-prone.
Red vs blue LED light: which is better?
Neither is universally better. The right choice depends on your skin goal.
- Choose red for smoothness, firmness and radiance.
- Choose blue for clarity and balance.
- Choose pink for a combined, all-round routine.
You can also alternate modes across the week. For example, someone with occasional blemishes might use blue or pink mode when congestion appears and red mode during the rest of their routine.
Skin changes from day to day, so your LED routine does not have to remain exactly the same all year.
Does the number of LEDs matter?
LED count is useful, but it is not the only measure of an effective mask.
The Wireless LED Mask PRO contains 72 light-source clusters and 288 individual LED chips. Each cluster brings the selected wavelengths close to the skin across the treatment area.
When comparing devices, consider:
- The wavelengths used
- Irradiance, or the amount of light delivered over a given area
- How evenly the light covers the face
- How close the LEDs sit to the skin
- Session duration
- Comfort and ease of consistent use
A powerful device is not automatically a better device. LED skincare relies on an appropriate combination of wavelength, output and exposure time.
Why fit and coverage matter
Light can only reach the areas the device covers. A flexible mask helps bring the LEDs closer to the contours of the face and reduces large gaps between the device and the skin.
The Me Time Ritual mask is made from soft, flexible silicone and is designed to cover the forehead, cheeks, chin, jawline and area around the mouth. Its continuous eye opening helps make the mask feel less restrictive, while its wireless design allows you to move around during your session.
That convenience is more than a lifestyle feature: the easier your mask is to use, the easier it is to maintain a consistent routine.
How often should you use an LED face mask?
Begin with 10-minute sessions around three times per week. Start on the lowest intensity and increase gradually if your skin remains comfortable.
For best results:
- Cleanse your skin and allow it to dry completely.
- Put on the mask and adjust the strap comfortably.
- Select your preferred mode, intensity and session time.
- Relax—or continue with your day while the mask works wirelessly.
- Remove the mask and wipe it with a soft, slightly damp cloth.
- Continue with the rest of your skincare routine.
Consistency matters more than choosing the longest session. Follow the user manual and do not exceed the recommended frequency or treatment time.
Can you use skincare products with LED light therapy?
For a straightforward routine, use the mask on clean, dry skin before applying serums, oils or moisturisers. This also helps keep the silicone clean.
Do not combine your LED session with photosensitising ingredients unless a qualified professional or the ingredient manufacturer confirms that the combination is appropriate. If you are using prescription skincare or medication that can increase sensitivity to light, consult your doctor before use.
Is LED light therapy suitable for everyone?
LED devices are generally designed to be gentle, but they are not suitable for everyone.
Do not use the mask without professional advice if you have a photosensitive condition, take photosensitising medication, have certain eye conditions, have active lesions or open wounds in the treatment area, have an implanted electronic device, recently underwent a facial procedure, or have a history of light-triggered reactions.
The device has not been specifically tested during pregnancy or breastfeeding. Consult your doctor or qualified healthcare professional before use.
Always perform a sensitivity test before your first full session and stop using the device if you experience pain, persistent redness, itching or unexpected discomfort. Read the complete user manual before use.
The bottom line
The colour of an LED is more than a visual effect: it represents a wavelength selected for a particular interaction with the skin.
Red light is the natural choice for a smoother, firmer and more radiant-looking complexion. Blue light is best suited to routines focused on clarity and balance. Near-infrared light cannot be seen, but it complements visible wavelengths by supporting overall skin renewal. And pink mode combines visible red and blue light for a simple, all-round treatment.
The most effective mode is ultimately the one that matches your skin goals—and the most effective routine is one you can maintain consistently.

Frequently asked questions
Is near-infrared light a colour?
Near-infrared is part of the electromagnetic spectrum, but it sits beyond the range visible to the human eye. You cannot see 850 nm near-infrared light when it is operating.
Is pink light its own wavelength?
No. In the Wireless LED Mask PRO, the pink appearance comes from red and blue visible LEDs operating together.
Can I alternate LED colours?
Yes. You can choose different modes on different days according to how your skin looks and feels. Follow the recommended session frequency in the user manual rather than stacking multiple long sessions.
Should LED light therapy feel warm?
Mild warmth can occur, but the treatment should not feel painful or uncomfortably hot. Stop the session if you experience unexpected discomfort.
How quickly will I see a difference?
LED skincare is based on consistency rather than an instant transformation. Timeframes vary according to the concern, device, routine and individual skin. Photographing your skin in the same natural lighting every two to four weeks can help you notice gradual changes.
