Red Light Therapy for Collagen Production: How It Works
Collagen is the protein responsible for keeping skin firm, plump, and structurally sound, and it is also one of the first things we start to lose as we age. It is no surprise, then, that red light therapy for collagen production has become one of the most searched topics in modern skincare.
Here is a closer look at how collagen actually declines over time, what the research says about red and near-infrared light's role in supporting it, and how to use LED therapy effectively for this purpose.
Why Collagen Matters, and Why It Declines
Collagen makes up a significant portion of the skin's structural framework, giving it firmness and elasticity. Natural collagen production slows gradually with age, and this decline is accelerated by cumulative sun exposure, which breaks down existing collagen fibres faster than the body can replace them.
This is why signs of ageing, such as fine lines, sagging, and a loss of bounce, tend to become more noticeable over time. Supporting the body's own collagen-producing processes has therefore become one of the central goals of modern, non-invasive skincare.
How Red Light Therapy Is Thought to Support Collagen
Red and near-infrared light therapy, also called photobiomodulation, works by delivering specific wavelengths of light that are absorbed by mitochondria, the energy-producing structures within skin cells. This process is understood to support the cellular energy needed to drive collagen synthesis.
A widely cited review published in Seminars in Cutaneous Medicine and Surgery describes how red and near-infrared light can stimulate fibroblasts, the cells responsible for producing collagen, and outlines a landmark study in which pulsed 660nm LED light applied to tissue-engineered human skin led to a measurable increase in collagen and a corresponding decrease in the enzyme responsible for breaking it down.
That same research included a clinical, split-face study on individuals with aged and photoaged skin. Following a course of twelve LED treatments, more than 90 percent of participants showed a reduction in wrinkle depth and surface roughness, and 87 percent reported an improvement in their wrinkle severity score.
What More Recent Research Has Found
More recent laboratory research has continued to build on these findings.
A study published through the Journal of the American Academy of Dermatology examined the effect of low-level red and infrared light on human skin explants (a small piece of living tissue taken from a plant or an animal and placed into a sterile growth medium) and found it increased the expression of collagen types Col1A1 and Col1A3, along with elastin and hyaluronic acid, even at relatively low energy levels.
The researchers noted this suggests potential for daily, at-home treatment protocols for people dealing with visible signs of photoaging.
Separately, research examining red and near-infrared light combinations on human skin in vitro found that combining the two wavelengths produced measurable increases in both collagen and elastin expression, supporting the idea that red and near-infrared wavelengths may work complementarily rather than redundantly.
Why Wavelength and Delivery Matter
Not all LED devices are created equal, and the research is fairly specific about which wavelengths tend to be most effective. Red light in the 630 to 660 nanometre range and near-infrared light around 830 to 850 nanometres are the wavelengths most consistently associated with collagen-related benefits in published research.
How the light is delivered also appears to matter. Some research into pulsed light delivery, as opposed to continuous wave light, suggests that pulsing may help optimise the cellular response while reducing the build-up of free radicals that can occur with prolonged, uninterrupted exposure.
Maysama's AURA LED Light Therapy Face Mask uses red (630nm) and near-infrared (830nm) wavelengths through its Intelligent Micro-pulsing Technology, delivered via a flexible, contoured silicone design intended to maintain close, even skin contact. The PRANA LED Light Therapy Mask offers a similar red and near-infrared combination, using pulsed light at 100Hz across multiple modes.
Building a Routine for Collagen Support
Consistency plays a bigger role in collagen-related results than intensity. Most manufacturers, including Maysama, recommend three to five sessions per week, with each session lasting around six minutes when using red and near-infrared light together.
Because visible collagen remodelling takes time, most people begin noticing early changes around the four-week mark, with more meaningful improvements developing over two to three months of consistent use.
Pairing your LED sessions with an antioxidant serum, such as Maysama's Green Rooibos Pressed Serum, may help support the skin further by buffering oxidative stress generated during treatment.
Collagen Supplements Versus Light Therapy
It is worth touching on how red light therapy relates to collagen supplements, since the two are often discussed together. They work through entirely different mechanisms, which is why many people use both rather than choosing one over the other.
Red light therapy supports the skin's own collagen-producing fibroblasts directly at the cellular level, while oral supplements provide amino acid building blocks the body may draw on more broadly. Neither replaces the other, and combining the two is a reasonable approach if you are looking to support collagen from multiple angles.
A Realistic Perspective
Red light therapy is not a substitute for collagen-boosting procedures like microneedling or laser resurfacing, nor does it work as quickly. What it offers is a gentle, non-invasive, low-downtime option that can be used regularly at home, with a genuinely supportive body of published research behind it.
Results also vary from person to person, depending on factors like age, skin condition, and consistency of use, so it is worth approaching red light therapy with realistic expectations rather than assuming dramatic overnight change.
Final Thoughts
The relationship between red light therapy and collagen production is one of the more well-researched areas in photobiomodulation, with multiple studies pointing to measurable increases in collagen and related structural proteins following consistent LED use. While it will not replace more invasive treatments, it offers a genuinely evidence-backed, low-risk way to support your skin's natural collagen production over time.
