If you have ever searched for a non-invasive way to firm your skin and reduce fine lines, chances are you have come across red light therapy. Once reserved for dermatology clinics and wellness spas, this technology is now available in sleek, at-home devices. But beyond the beauty buzz, what does red light therapy actually do for your skin? And how exactly does it help boost collagen?
Let’s take a closer look at the science behind red light therapy and why it is gaining such popularity among skincare professionals and beauty enthusiasts alike.
What Is Red Light Therapy?
Red light therapy, sometimes referred to as low-level light therapy (LLLT), involves exposing the skin to wavelengths of red or near-infrared light. These wavelengths typically range from 630 to 850 nanometres, which allows them to penetrate the skin at various depths.
Unlike UV rays from the sun, red light is not harmful and does not cause burning or damage. Instead, it works by stimulating energy production within skin cells, encouraging repair and regeneration. The process is pain-free and has no downtime, making it ideal for regular at-home use.
How Does Red Light Stimulate Collagen?
The key to red light therapy’s anti-ageing powers lies in its effect on the mitochondria, the energy-producing structures inside cells. When red light is absorbed by the skin, it helps increase the production of adenosine triphosphate (ATP), the molecule that fuels cellular activity.
With more energy available, skin cells can function more efficiently. This includes fibroblasts, which are responsible for producing collagen and elastin. As fibroblasts are energised, they start creating more of the proteins that keep skin plump, firm and elastic.
Collagen naturally declines with age, leading to sagging and wrinkles. By encouraging the skin to produce more of it, red light therapy helps slow down and even reverse some of these signs of ageing.
What Kind of Results Can You Expect?
While red light therapy is not a miracle cure, clinical studies and real-world results show it can deliver noticeable improvements when used consistently. Over time, users report:
- A reduction in fine lines and crow’s feet
- Improved skin firmness and elasticity
- Brighter, more even skin tone
- Faster healing from inflammation or cosmetic treatments
Most people begin to see subtle results within 4 to 6 weeks, with continued improvements over several months of regular use. The key is consistency. Like going to the gym, the benefits of red light therapy build up with time and repetition.
How to Incorporate Red Light Therapy into Your Routine
Using red light therapy at home is easier than ever. Many devices are designed for comfortable, hands-free use and require only a few minutes a day. Start by cleansing your skin to remove makeup or sunscreen, then follow the usage instructions for your chosen device.
Depending on the design, you might use your device three to five times per week for 10 to 20 minutes per session. It pairs well with a minimalist skincare routine focused on hydration and repair. Avoid harsh exfoliants or strong actives right before your session, especially if your skin is sensitive.
To maximise results, treat red light therapy as a long-term investment in your skin’s health. Make it part of your morning or evening ritual, just like brushing your teeth or applying moisturiser.
Final Thoughts
Red light therapy offers a science-backed, non-invasive way to support collagen production and maintain youthful-looking skin. By energising your cells at the source, it promotes natural repair and resilience without the need for needles or downtime.
If you are looking to bring this technology into your routine, consider investing in a high-quality LED light therapy mask, like the one from Maysama, that makes consistent treatment easy and effective. With regular use, you may be surprised at just how much your skin can glow from within.
