Red light therapy anti-aging properties
A few weeks ago, I spent some time with a friend who was visiting. She represents several beauty brands—ranging from lotions to cosmetics—so, understandably, she’s quite meticulous about her skincare routine. During her stay, she introduced me to a small, portable red light therapy device she carries with her everywhere. She swears by it. According to her, the red light helps skincare products penetrate deeper into the skin—and that piqued my curiosity.
I had heard of Red Light Therapy (RLT) before, but I hadn’t looked into it deeply. Her glowing recommendation inspired me to dive into what seems to be a growing trend in non-invasive, anti-aging treatments.
What Is Red Light Therapy?
Technically known as photobiomodulation or photomedicine, Red Light Therapy uses low-wavelength red light to address a wide range of concerns—everything from nerve pain and muscle recovery to inflammation, acne, cold sores, wound healing, and even fine lines and wrinkles.
When it comes to nerve pain, RLT works by activating a specific protein located on the surface of neurons. This activation reduces the cells' ability to receive and transmit pain signals. For muscle recovery, it stimulates the mitochondria—the energy powerhouses of our cells—boosting the body’s natural healing process. As someone who exercises regularly, this particular benefit definitely caught my attention. But I was equally intrigued by the skin-rejuvenating potential.
A Modern Approach Rooted in Ancient Wisdom
The use of light as a therapeutic tool isn’t new. Sunlight has been used in healing practices for thousands of years, from ancient Egyptian rituals to Ayurvedic and Traditional Chinese Medicine. But the advent of electricity has taken this ancient principle to new heights.
Today, science is catching up. Multiple studies have demonstrated the physiological benefits of red and near-infrared light, especially when it comes to improving skin texture, firmness, and tone. One controlled trial, for example, had participants undergo 30 sessions of light exposure between 611–650 nm and up to 850 nm. The results showed not just improved complexion and skin feel, but also structural changes in intradermal collagen—a key factor in reducing fine lines and wrinkles.
How Red Light Affects the Skin
In simple terms, red light waves penetrate the skin’s layers, stimulating cellular metabolism and intracellular communication. This process reduces inflammation, encourages cell regeneration, and enhances skin elasticity.
The result? Smoother, clearer, and more radiant skin.
Red light therapy (RLT) has shown to significantly reduce inflammation.
Choosing the Right Device
When I decided to try RLT for myself, I debated between a full-face mask (often bulky and expensive), a handheld wand, and a more versatile wand-like device. I ultimately opted for the latter so I could use it not only on my face but also on sore muscles and my lower back.
If you're thinking of purchasing a home-use red light therapy device, here are a few key things to consider:
Wavelength matters: Look for devices with red light in the 620–750 nm range. If you’re interested in deeper penetration (especially for muscle recovery), opt for near-infrared light above 750 nm.
Focus on red, not the rainbow: While some devices offer a full spectrum of light colors, quality red light is more than sufficient for most skincare and wellness benefits.
Protect your eyes: Never look directly into the light and consider wearing protective goggles during use.
Manage your expectations: RLT can help reduce fine lines and improve skin tone, but deep wrinkles may require professional, in-office treatments like lasers or microneedling.
Consistency is key: As with any beauty or wellness routine, regular use delivers the best results.
Boosting Results with a Healthy Lifestyle
To maximize the benefits of red light therapy, pair it with a healthy, balanced lifestyle. This includes:
Eating plenty of leafy greens and antioxidant-rich foods
Drinking at least one liter of water per day
Using SPF daily—even when indoors
Prioritizing sleep, movement, and stress management
You might also consider adding a supplement like Astaxanthin, which supports skin texture and firmness from the inside out. One of our favorites is the Semaine Hair & Skin Gummy, which combines astaxanthin, biotin, and collagen to help you glow from within.
