The Science Behind the Glow
To get started, it’s crucial to understand the term nanometers, which measures wavelengths of light and determines how far light can travel. Consider the entire light spectrum, ranging from ultraviolet (UV), spanning all the visible colours, to infrared, which is invisible to the human eye.
The Wavelengths you need to look out for when purchasing an in home LED Mask are the following clinically proven wavelengths:
🔷 Blue Light (460nm): Reach the epidermis and eliminate acne-causing bacteria. Over two decades of research have proven its efficacy.
🔶 Yellow Light (590nm): Delve into the dermis to soothe inflammation, pigmentation, and sensitivity issues like rosacea.
🔴 Red Light (633nm): Penetrate deep into the hypodermis, boosting collagen production and aiding in skin preservation.

It’s science fact that our skin absorbs light
Our skin is our bodies largest organ. It is scientifically proven to absorb light.
So given blue is a short wavelength at 460nm, blue light has been clinically proven to reach the epidermis and kill acne causing bacteria. There is over two decades of clinical research and studies that support this.
Yellow light travels further at the specific nanometer or 590 and reaches the dermis and helps with inflammation ad pigmentation. Along with skin sensitivities such as Roscacea.
And then there is RED LIGHT at 633 nm is clinically proven to travel way down to the hyper dermis.It works on a cellular level to help boost collagen production and help with skin preservation.
Infrared light at 850nm travels even further and really super charges our collagen making production and blood flow. Infrared can be used in conjunction with the other light modes to really boost your treatment.
A Fusion of Skincare and Science
While this might feel like a lot to absorb, it’s crucial to know that LED light therapy isn’t just a passing fad or a fancy gadget. It’s categorised as a medical device and is approved by organisations like the FDA and TGA. This is a beautiful blend of skincare science and self-love, promising tangible results with consistent use.So, if you’re considering investing in a home LED face mask, look for devices that offer these clinically proven wavelengths.
