Understanding LED Light Therapy
What does led therapy do?
LED therapy is an effective way of treating a number of skin concerns such as acne, dullness and redness. If you have autoimmune issues such as rosacea, eczema or inflammation then LED therapy can help reduce these symptoms.
Does LED therapy actually work?
YES. As a medical professional, I’ve witnessed incredible results from LED therapy. BUT not all LED devices are created equal.Â
Some fail to deliver the wavelength needed for stimulating cellular responses. When choosing for the right home – use LED mask, the amount of light emitted from the bulbs really does make all the difference.Â

What does each light colour do?
Red Light (630nm)
Supporting Collagen Production
Red LED light is known for its ability to penetrate deeply into the skin, reaching the dermis layer where collagen production occurs. By stimulating fibroblasts, cells responsible for collagen synthesis, red light can help improve skin elasticity, reduce fine lines, and give skin a firmer, more youthful appearance.Â
This collagen-boosting effect makes red LED light a popular choice for those looking to address signs of aging and rejuvenate their complexion.
This gentle approach makes yellow LED light an ideal option for individuals with sensitive or reactive skin.
Yellow Light (590nm)
Enhancing Radiance and Reducing Redness
Yellow LED light operates within a wavelength range that stimulates the skin’s outer layers, enhancing blood circulation and promoting cell renewal. It’s known for its calming effects, helping to reduce redness and soothe sensitive skin. Yellow light therapy can also improve overall skin tone, giving the complexion a natural, healthy glow.
Blue Light (460nm)
A Targeted Approach to Acne
Blue LED light is effective in addressing acne by reducing the activity of sebaceous (oil) glands and targeting acne-causing bacteria on the skin’s surface. By controlling oil production and diminishing bacteria, blue light helps prevent the formation of new breakouts and promotes a clearer, healthier complexion.
When combined with red light, it creates a powerful synergy, with blue light treating the source of acne and red light reducing inflammation and supporting skin healing.
Infrared light is also valued for its therapeutic effects, including pain relief and faster healing, making it a holistic addition to any skincare routine.
Infrared Light (850nm)
Supporting Deeper Skin Health and Wellness
Infrared LED light penetrates deeper than visible light, reaching the subcutaneous layers where it influences circulation, nutrient delivery, and cellular repair. This wavelength is particularly beneficial for reducing fine lines and improving skin elasticity, supporting overall skin wellness from the inside out.
Key Terminology
Blue Light
A visible wavelength that appears blue and targets the epidermis, often used to treat acne.
Dermis
The middle layer of skin, where collagen and elastin are produced.
Epidermis
The skin’s outermost layer, the visible layer that protects against environmental factors.
Irradiance
The intensity of light energy delivered to the skin; critical for determining LED therapy’s effectiveness.
LED
Stands for Light Emitting Diode, a technology that produces specific wavelengths for therapeutic purposes.
Light Wavelengths
The distance between two peaks in a wave of light, measured in nanometres (nm); determines the depth of skin penetration.
Nanometres (nm)
A unit of measurement for light wavelengths; a billionth of a meter.
Near-Infrared Light
A wavelength beyond visible light, reaching the subcutaneous layer for deeper skin benefits.
Red Light
A visible wavelength appearing red, known for stimulating collagen production.
Subcutaneous Layer
The innermost layer of skin, containing connective tissue and fat.
Ultraviolet (UV)
A type of electromagnetic radiation not visible to the human eye; associated with sun exposure and skin aging.
