Firm, plump skin relies heavily on collagen, and it is one of the first things to decline as we get older. Given how central it is to the way skin looks and feels, it is no wonder that red light therapy for collagen production, sometimes searched as collagen light therapy, has become such a popular topic among people exploring at-home skincare devices.
Below, we break down how collagen light therapy is understood to work, what the research shows, and how to build it into your routine effectively.
Understanding Collagen Decline

Collagen is the structural protein that gives skin its firmness and bounce. Natural production slows gradually with age, and cumulative sun exposure accelerates this decline considerably, breaking down existing collagen fibres faster than the body can replace them.
This combination is largely why visible signs of ageing, including fine lines, sagging, and a loss of elasticity, tend to become more pronounced over the years. It is also why so much of modern skincare is focused on supporting the body's own collagen production rather than relying solely on topical fillers.
How Collagen Light Therapy Is Thought to Work
Red and near-infrared light therapy, also known as photobiomodulation, works by delivering specific wavelengths of light that are absorbed by mitochondria, the energy-producing structures inside skin cells. This is understood to support the cellular energy required to drive collagen synthesis.
A frequently cited review published in Seminars in Cutaneous Medicine and Surgery outlines a landmark study in which pulsed 660nm LED light applied to tissue-engineered human skin resulted in a measurable increase in collagen alongside a reduction in the enzyme responsible for breaking it down.
The same research included a clinical, split-face study involving individuals with aged and photoaged skin. After a course of twelve LED treatments, more than 90 percent of participants showed reduced wrinkle depth and surface roughness, with 87 percent reporting an improved wrinkle severity score.
More Recent Findings
More recent laboratory research has reinforced these earlier 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 and found it increased expression of collagen types Col1A1 and Col1A3, alongside elastin and hyaluronic acid, even at relatively low energy levels.
Separately, research into combined red and near-infrared wavelengths applied to human skin in vitro found measurable increases in both collagen and elastin expression, supporting the idea that these two wavelengths may work together rather than simply duplicating each other's effects.
Why Wavelength and Device Design Matter
The published research is fairly specific about which wavelengths are most consistently associated with collagen-related benefits. Red light around 630 to 660 nanometres and near-infrared light around 830 to 850 nanometres appear most frequently across the relevant studies.
How the light reaches the skin matters too. Devices that maintain close, even skin contact are generally considered more effective than those with gaps or uneven coverage, since light can scatter and lose intensity before it is properly absorbed.

Maysama's AURA LED Light Therapy Face Mask uses red (630nm) and near-infrared (830nm) wavelengths delivered through Intelligent Micro-pulsing Technology™, in a flexible, contoured silicone design intended to maintain close contact across the face.
The PRANA LED Light Therapy Mask offers a similar red and near-infrared combination using pulsed light at 100Hz.
Building a Realistic Routine
Consistency matters far more than intensity when it comes to collagen-related results. Most manufacturers, including Maysama, recommend three to five sessions per week, with each session lasting around six to ten minutes when using red and near-infrared light together.
Because visible collagen remodelling takes time, most people notice early changes around the four-week mark, with more meaningful improvement developing over two to three months of regular use. Pairing your sessions with an antioxidant serum, such as Maysama's Green Rooibos Pressed Serum, may help support the skin further during treatment.
Maysama also discusses how to avoid overdoing your sessions in Can You Overdo Your Red Light Therapy?, which is worth reading if you are new to building a consistent LED routine.
Pairing Light Therapy With Your Skincare Actives

Many people wonder whether it is worth combining collagen light therapy with other skincare actives rather than using it alone.
Antioxidant serums, such as Maysama’s Green Rooibos Serum, are a natural pairing, since red light therapy itself can generate a degree of oxidative activity in skin cells as part of the process behind its benefits, and an antioxidant may help support the skin during treatment.
Introducing any new active gradually, rather than layering several new products at once, makes it easier to spot how your skin is responding and adjust your routine accordingly.
Setting Realistic Expectations
Red light therapy is not a replacement for more invasive collagen-boosting procedures such as microneedling or laser resurfacing, and it works considerably more gradually. What it does offer is a genuinely evidence-supported, low-downtime option that fits easily into a regular routine at home.
Results vary from person to person depending on age, skin condition, and how consistently the device is used, so it is worth approaching collagen light therapy with realistic expectations rather than anticipating dramatic, overnight change.
Final Thoughts
The link between red light therapy and collagen production is one of the better-researched areas within photobiomodulation, with multiple studies pointing to measurable increases in collagen and related proteins following consistent LED use. While it will not replace more invasive treatments, it offers a genuinely evidence-backed way to support your skin's natural collagen production over time.
The best results tend to come from treating collagen light therapy as a long-term habit rather than a short course, since the underlying biology it supports, fibroblast activity and cellular energy production, benefits from ongoing, rather than occasional, stimulation.
