As skincare enters a more advanced era, certain technologies are beginning to shape the conversation in a deeper, more meaningful way. Photobiomodulation is one of them.
It sounds clinical, and in many ways it is, but at its core, photobiomodulation is simply the use of specific light wavelengths to support the skin in a more intelligent way. It is the science behind why red light and near infrared have become such important parts of modern beauty, and why light based skincare now feels less like a trend and more like the future.
Because this is not about skincare that sits on the surface alone. It is about supporting the skin in a way that feels more layered, more considered and more aligned with where beauty is heading.
In this guide, we take a closer look at what photobiomodulation actually is, how it works, and why it sits at the centre of some of Liorae’s most advanced devices.
What Is Photobiomodulation?
Photobiomodulation, often shortened to PBM, refers to the use of targeted light wavelengths to encourage beneficial biological activity within the skin.
Different wavelengths reach different depths, which means they can support the skin in different ways. Some are associated with visible radiance and rejuvenation. Others are discussed in relation to deeper support, firmness and resilience beneath the surface.
What makes PBM so compelling is that it feels both highly advanced and beautifully gentle. It is:
- non invasive
- pain free
- suitable for most skin types
- widely researched
- relevant for both short term glow and long term skin support
This is one reason photobiomodulation appears not only in premium skincare devices, but also in dermatology, recovery treatments and other clinically aligned settings where regeneration and repair matter.
How Photobiomodulation Works
At the heart of photobiomodulation is the way light interacts with the cells.
When the skin is exposed to specific wavelengths, particularly red light and near infrared, that light energy is absorbed by the mitochondria within the cells. Mitochondria are often described as the energy centres of the cell, responsible for producing ATP, the fuel that supports cellular activity.
In simple terms, photobiomodulation helps create the conditions that allow the skin to function more efficiently.
This can support:
- cellular energy production
- skin recovery processes
- collagen focused rituals
- circulation
- overall skin vitality
- a complexion that looks healthier, fresher and more resilient
This is exactly why PBM feels so exciting within skincare. It offers something beyond product alone. Something more refined, more advanced and more aligned with the way the skin actually works.
Red Light and Visible Rejuvenation
Red light, usually in the range of 625 to 660nm, is one of the most recognisable wavelengths in skincare and for good reason.
It is commonly associated with the mid layers of the skin, where it supports a complexion that looks more radiant, refreshed and visibly revitalised. It is also one of the most established entry points into light therapy because it feels both approachable and effective.
Red light is often chosen in routines focused on:
- visible radiance
- fine lines
- smoother looking texture
- a more even looking complexion
- overall skin vitality
This is one reason it appears so often in modern beauty technology. It is elegant, versatile and deeply relevant to the way many women want to care for their skin now.

Near Infrared and Deeper Support
If red light is the familiar face of light therapy, near infrared is often its quieter luxury counterpart.
Usually discussed in the range of 780 to 850nm, near infrared reaches deeper than visible red light. It is often associated with support beneath the surface, which is why it appears so often in more advanced devices designed for a more complete rejuvenation ritual.
Near infrared is commonly discussed in relation to:
- firmness
- elasticity
- resilience
- recovery
- deeper rejuvenation support
- a more comprehensive treatment experience
This is part of what makes the pairing of red light and near infrared so compelling. One supports visible rejuvenation, while the other adds a more layered depth to the ritual. Together, they create something more complete.
Why Multi Wavelength Devices Feel More Elevated
Photobiomodulation becomes even more interesting when more than one wavelength is used together.
Rather than relying on one light mode alone, multi wavelength devices create a broader treatment experience by supporting the skin at different depths. This allows the ritual to feel more complete, more intentional and ultimately more luxurious in the truest sense of the word.
A well designed multi wavelength device can support:
- visible brightness
- skin vitality
- firmness
- resilience
- a more layered rejuvenation experience over time
This is exactly why advanced devices like Luma9™, LiftXR™ and Mango+ Pro™ combine multiple wavelengths. It is not about doing more for the sake of it. It is about creating a treatment ritual that feels more intelligent and more aligned with the skin’s complexity.
PBM and the Modern Beauty Ritual
Photobiomodulation works differently from technologies like EMS and RF.
EMS is more closely associated with muscle stimulation. RF is often discussed in relation to heat based collagen support. PBM, by contrast, is centred on light and the cellular environment, supporting the skin in a way that feels quieter but no less powerful.
That is also why it pairs so beautifully with other technologies.
Within a broader at home ritual, PBM can sit alongside:
- EMS for a more active facial ritual
- RF for a more advanced multi technology treatment
- skin prep tools for a more considered routine overall
Together, these technologies create the kind of skincare routine modern beauty is moving towards. Not one dimensional. Not surface level. But layered, intentional and designed to work with the skin in a more complete way.
Where PBM Fits Into an At Home Routine
One of the reasons photobiomodulation has become such a defining part of modern beauty is because it lends itself so naturally to consistency.
It is not a one off treatment. It is a ritual. Something that becomes part of your week, your evening, your version of skincare that feels a little more elevated and a little more future facing.
Within an at home routine, PBM can be part of:
- regular LED mask sessions
- red light and near infrared rituals
- combined treatments using multi technology devices
- long term skin support focused on vitality, brightness and firmness
This is where devices like Luma9™, LiftXR™ and Mango+ Pro™ fit so seamlessly. They allow clinically inspired light therapy to move into real life in a way that feels wearable, refined and genuinely usable.
Why Liorae Uses Clinically Aligned Wavelengths
At Liorae, the wavelengths used across your light based devices are selected with intention.
That includes:
- Red Light: 625 to 660nm
- Near Infrared: 780 to 850nm
- Blue Light: 460nm in Nano Comb™
These are the wavelengths most closely associated with the skin goals women are actively seeking to support, from visible rejuvenation and radiance to deeper firmness and more advanced scalp focused care.
Paired with flexible silicone designs, multi wavelength systems and thoughtfully designed treatment formats, they allow for a more considered approach to at home skincare technology.
Final Thoughts
Photobiomodulation may sound highly technical, but in practice, it represents one of the most elegant shifts happening in skincare right now.
It reflects a move away from routines built only around products and towards something more intelligent. More layered. More clinically inspired. A way of supporting the skin that feels as modern as it does effective.
Whether your focus is brightness, firmness, resilience or a more complete rejuvenation ritual, photobiomodulation helps explain why red light and near infrared have become such important parts of advanced beauty.
And with devices like Luma9™, LiftXR™ and Mango+ Pro™, that technology becomes something you can bring into your routine in a way that feels elevated, wearable and entirely designed for real life.
