Understanding The Layers Of Your Skin

To understand why wavelength matters, it helps to first understand what LED Light Therapy is actually trying to reach. The skin is broadly divided into three primary layers: the epidermis, dermis and hypodermis.

The epidermis forms the outer protective layer of the skin. This is where many concerns we can see at the surface become apparent, including changes in tone, pigmentation and texture. Beneath it lies the dermis, the structural layer of the skin. It contains fibroblasts and much of the skin's collagen and elastin network, which help provide strength, firmness and elasticity.

Deeper still is the hypodermis, or subcutaneous tissue, composed primarily of connective and adipose tissue.

Ageing affects these layers differently. Collagen production slows, fibroblast activity changes, cellular energy production becomes less efficient and the structural integrity of the skin gradually declines. The result eventually becomes visible at the surface as fine lines, wrinkles, changes in texture and loss of firmness.

Why Different Wavelengths Reach Different Depths

Light is measured in nanometres, or nm, and wavelength influences how light interacts with biological tissue. Shorter visible wavelengths generally interact more superficially within the skin. As wavelengths move through Red and into the Near-Infrared spectrum, light can penetrate more deeply into tissue.

This is why effective LED Light Therapy is not simply about how many lights a mask contains. It is about which wavelengths are being delivered, where those wavelengths travel and what biological processes they are designed to support.

What Is Photobiomodulation?

LED Light Therapy works through a process known as photobiomodulation. Specific wavelengths of light can interact with photoacceptors within cells, including within the mitochondria. Mitochondria are responsible for producing adenosine triphosphate, or ATP, the primary energy source cells use to carry out biological functions.

Skin renewal requires energy. Cellular repair requires energy. Collagen-related processes require energy. By supporting mitochondrial and cellular activity, photobiomodulation is being investigated for its ability to support many of the biological processes associated with healthier-looking skin. This same relationship between light, mitochondria and ATP is central to the science behind our Laser technology.

1072nm: Taking At-Home LED Deeper

Red and Near-Infrared wavelengths have formed the foundation of many at-home LED devices. 1072nm Long-Wave Near-Infrared Light extends further into the Near-Infrared spectrum.

Its longer wavelength allows light to penetrate deeper into skin tissue than shorter visible wavelengths, expanding the depths at which an at-home LED device can deliver light. This is why we introduced 1072nm into the Advanced Pro LED Face Mask. Rather than replacing traditional Red or Near-Infrared Light, 1072nm adds another depth to the treatment.

In TIGHTEN mode, 630nm Red, 850nm Near-Infrared and 1072nm Long-Wave Near-Infrared Light work together to provide multi-depth light delivery designed to support cellular energy, collagen activity and renewal while targeting visible concerns including fine lines, wrinkles and loss of firmness.

Why Five Wavelengths Instead Of One?

Different skin concerns do not originate from exactly the same biological processes or occur at exactly the same depth. That is why the Advanced Pro LED Face Mask was engineered around five targeted wavelengths rather than a single light source.

415nm Blue Light is used within CLARIFY for breakouts and blemishes.

590nm Yellow Light features across ILLUMINATE, DAILY and EVENING ROUTINE for concerns including dullness, radiance and uneven-looking tone.

630nm Red Light is used across REFINE, ILLUMINATE, TIGHTEN and DAILY to support cellular energy, collagen-related processes and skin renewal.

850nm Near-Infrared Light extends light delivery deeper and is used within TIGHTEN and DAILY.

And 1072nm Long-Wave Near-Infrared Light, our deepest-reaching LED wavelength yet, extends the treatment further into the Near-Infrared spectrum.

Together, these wavelengths create a more comprehensive approach to photobiomodulation, allowing one device to address multiple concerns through six targeted treatment modes.

What Our Six-Week Results Tell Us

Technology specifications can tell us how a device works. What ultimately matters is whether consistent use translates into a visible difference in the skin.

Following six weeks of regular use of the Advanced Pro LED Face Mask according to the recommended treatment protocol:

82% reported the appearance of fine lines looked softer within 6 weeks.*

The result is particularly relevant when considered alongside the technology behind the mask. Fine lines are visible at the surface, but many of the processes influencing their development involve changes occurring beneath it.

The Advanced Pro LED Face Mask was designed around that understanding, using multiple wavelengths to deliver light at different depths rather than approaching skin as a single surface.

The Future Of LED Is Multi-Wavelength

The next generation of at-home LED is not simply about adding more LEDs or increasing intensity. It is becoming more precise.

Different wavelengths. Different depths. Different applications.

By combining 415nm Blue, 590nm Yellow, 630nm Red, 850nm Near-Infrared and 1072nm Long-Wave Near-Infrared Light, the Advanced Pro LED Face Mask represents our move towards a more targeted approach to at-home photobiomodulation.
