When it comes to skin health, pain relief, and overall wellness, light-emitting diode (LED) light therapy has become a popular solution. But with multiple treatment colours and each claiming different benefits, how do you know which one is right for you?
Different LED light therapy colours penetrate the skin at varying depths, influencing biological processes in distinct ways. Whether you're looking to reduce wrinkles, clear acne, or promote muscle recovery, choosing the right wavelength can maximise results.
Learn the differences between these colours and understand which light is best for your specific goals with our experts at Rojo Light Therapy AUS.
LED light therapy is a non-invasive treatment that uses specific wavelengths of light to stimulate cellular processes. Unlike UV light, which can cause skin damage, LED light is safe and does not emit heat or radiation.
Each wavelength, measured in nanometres (nm), determines how deeply the light penetrates and which biological mechanisms it influences.
What makes LED therapy so effective is how these wavelengths interact with chromophores, which are molecules in our cells that absorb light energy. This process stimulates adenosine triphosphate (ATP) production, which fuels cellular repair, regeneration, and overall health.
By selecting the right wavelength for a specific concern, users can achieve targeted and effective results.
Red light therapy is one of the most extensively researched forms of LED treatment. At wavelengths between 620 and 700 nam, red light penetrates deep enough to reach the dermis, where it stimulates fibroblasts, a type of cell responsible for collagen and elastin production. This makes it an excellent treatment for reducing fine lines, wrinkles, and sagging skin.
Clinical studies have also shown that red light therapy can stimulate hair follicles, making it an effective treatment for hair loss conditions such as androgenetic alopecia.
Beyond skincare, red light therapy also helps accelerate muscle recovery and relieve pain.
By increasing blood circulation and reducing oxidative stress, it speeds up the body’s natural healing processes. This is particularly beneficial for athletes, individuals with arthritis, or anyone dealing with chronic muscle pain.
Blue light operates at a shorter wavelength than red light therapy. It primarily affects the epidermis or outermost layer of the skin, and is most known for killing P. acnes bacteria, the primary culprit behind breakouts.
Unlike harsh chemical treatments that can cause dryness and irritation, blue light therapy offers a gentle, non-invasive alternative that targets bacteria without harming the surrounding skin.
In addition to its antibacterial properties, blue light therapy helps regulate sebaceous (oil) gland activity, reducing excess oil production that can lead to clogged pores.
Some studies also suggest that blue light has calming effects on the nervous system, potentially helping to reduce stress-related breakouts.
Compared to blue light, green light penetrates slightly deeper into the dermis where it slows down the overproduction of melanin. This makes it highly effective for hyperpigmentation, sunspots, and uneven skin tone.
Another fascinating benefit of green light therapy is its potential to reduce redness and accelerate wound healing. This makes it a great option for individuals with rosacea or sensitive skin prone to irritation.
Yellow or amber light therapy is believed to improve lymphatic drainage, reduce inflammation, and enhance overall skin radiance. It has been shown to increase oxygen availability to skin cells, allowing for better cellular repair and faster recovery after treatments like microneedling or laser therapy.
Because yellow light stimulates the lymphatic system, it can help reduce swelling and puffiness, particularly around the eyes. It is also commonly used in post-surgical recovery treatments to minimise bruising and enhance healing.
Aside from the colours mentioned above, there are also others such as cyan, purple, and orange. However, currently, these colours have very little scientific support regarding their benefits.
For more powerful benefits, combining different wavelengths is effective. For instance, blue and red light therapy work exceptionally well together for acne-prone skin. Blue light eliminates acne-causing bacteria, while red light reduces inflammation and promotes faster healing, preventing long-term scarring.
By tailoring LED therapy treatments based on specific needs, users can achieve faster, more comprehensive results compared to using a single wavelength alone.
With LED light therapy, it’s not just about picking a colour. It’s about picking the right wavelength that will address your concerns. By incorporating multiple LED light colours into your wellness routine, you can create a customised approach that adapts to your skin’s needs over time.
