Photobiomodulation (PBM) is one of the most researched and clinically supported methods of improving skin health, cellular function and visible signs of aging. Although the word sounds complex, the mechanism is simple: specific wavelengths of light stimulate the skin and deeper tissues to improve how cells perform, recover and regenerate.
In this guide, we break down what photobiomodulation really is, how LED, Red Light and Near-Infrared wavelengths work, and why these technologies are used in advanced Liorae devices.
What Is Photobiomodulation?
Photobiomodulation is the use of targeted light wavelengths to trigger beneficial biological changes in the skin. These wavelengths penetrate the skin at different depths, influencing cells responsible for collagen, elasticity, inflammation, circulation and repair.
PBM is:
-
non-invasive
-
pain-free
-
backed by extensive research
-
suitable for most skin types
-
effective for both short-term and long-term rejuvenation
This is why PBM is used widely in dermatology, sports medicine, wound healing and premium at-home skincare devices.
How PBM Works on a Cellular Level
When the skin is exposed to specific wavelengths - typically Red Light (625–660nm) and Near-Infrared (780-850nm) - the mitochondria inside the cells absorb the light energy. Mitochondria act like tiny power plants, producing ATP (cellular energy).
Light exposure increases:
-
ATP production
-
cellular repair
-
collagen synthesis
-
circulation
-
antioxidant activity
This results in healthier, stronger, more resilient skin.
Red Light Therapy (625-660nm): Surface to Mid-Dermal Benefits
Red Light penetrates the mid-layers of the skin and directly interacts with fibroblasts, the cells that create collagen and elastin.
Benefits include:
-
enhanced collagen support
-
improved radiance and brightness
-
reduced redness and inflammation
-
smoother texture
-
faster recovery after irritation
-
softening of fine lines
Red Light is ideal for users seeking visible improvements without heat, downtime or irritation.
Near-Infrared Therapy (780–850nm): Deeper Rejuvenation
Near-Infrared Light reaches deeper into the tissues, targeting layers that Red Light cannot reach - including connective tissue and deeper dermal structures.
Benefits include:
-
improved firmness and elasticity
-
deep cellular repair
-
reduced inflammation
-
enhanced circulation
-
accelerated recovery
-
support for early skin laxity
NIR is a powerhouse wavelength for lifting and long-term anti-aging improvements.
Why LED Devices Use Multiple Wavelengths
PBM works best when the skin receives more than one wavelength. This is why advanced devices like Luma9™, LiftXR™ and Mango+ Pro™ combine multiple light types.
Layered wavelengths create:
-
surface brightness
-
mid-layer collagen improvement
-
deeper elasticity support
-
reduced inflammation
-
long-term rejuvenation
-
enhanced results when combined with EMS or RF
Multi-wavelength devices provide broader, more complete results compared to single-wavelength tools.
PBM vs. Other At-Home Technologies
Unlike RF or EMS, photobiomodulation does not affect muscle or deeper structural proteins directly. Instead, it enhances the cellular environment - making the skin healthier, stronger and more resilient.
PBM is often paired with:
-
EMS for muscle lift
-
RF for collagen tightening
-
Dermaplaning for improved LED absorption
Together, they create a multi-layer rejuvenation system.
Where PBM Fits Into an At-Home Routine
For best results, photobiomodulation should be used consistently, allowing skin cells to accumulate energy over time.
Recommended routine:
-
Luma9™ → 3-5x weekly for Red Light + NIR
-
LiftXR™ → LED/NIR combined with EMS activation
-
Mango+ Pro™ → Red Light & NIR paired with EMS + RF
-
LiorDerma™ → 1–2x weekly to improve light penetration
This routine supports brightness, firmness, texture, cellular repair and long-term anti-aging.
Why Liorae Uses Clinically Aligned Wavelengths
Your LED devices are designed using wavelengths supported by clinical literature:
-
Red Light: 625-660nm
-
NIR: 780-850nm
-
Blue Light (Nano Comb): 460nm
These wavelengths offer optimal penetration, safety and proven results.
Liorae’s flexible silicone, multi-wavelength systems and precision designs ensure the skin receives consistent, even exposure for maximum PBM benefits.
⭐ Final Thoughts
Photobiomodulation is more than a trend - it’s a scientifically validated method of improving skin quality at a cellular level. Whether you're targeting brightness, firmness, inflammation or long-term rejuvenation, Red Light and NIR wavelengths provide a powerful foundation for visible transformation.
With devices like Luma9™, LiftXR™ and Mango+ Pro™, PBM becomes accessible, safe and effective from home - supporting radiant, resilient, clinically rejuvenated skin.
