You may have heard the buzz around red light therapy and its supposed benefits, but what exactly are these benefits?
Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, isn’t new. It has been a topic of scientific study for decades, with researchers exploring its potential to enhance health and wellbeing in several fascinating ways.
But here's the catch — not all red light therapy devices are created equal.
According to Dr. Mitchell, "The research consistently shows that to reap the proven benefits, you need a medical-grade red light therapy panel."
While clinics offer these treatments at £50 or more per session, investing in a high-quality panel for home use is often more economically viable and convenient. You get the same medical-grade therapy in the comfort of your own home, whenever you need it, without the recurring costs or the hassle of booking appointments.
So, if you’re curious about how red light therapy might work for you, read on.
Here are 10 scientifically-backed benefits of red light therapy — and why choosing the right device makes all the difference.
1. Enhances Skin Health and Reduces Wrinkles, Scaring and Stretch Marks
Red light therapy can be a game-changer for your skin. By stimulating collagen production, it helps to reduce fine lines and wrinkles, improve skin texture, and increase skin elasticity.
In a study published in the Journal of Cosmetic and Laser Therapy, participants who underwent red light therapy treatments experienced a significant improvement in skin complexion and a reduction in the appearance of wrinkles.
Dr. Mitchell explains, “Red light penetrates deep into the skin layers, stimulating cellular repair and rejuvenation. It’s like giving your skin cells a boost of energy to perform at their best.”
However, it’s essential to use a device with sufficient power output to achieve these results. Medical-grade devices, such as the Solis Spectrum SOLO for example, which has an irradiance of 180mW/cm², provide the necessary power to stimulate real benefits.
Irradiance = the metric used to measure power output in Red Light devices.
While LED face masks have become popular, even the leading ones, like the Dr. Dennis Gross mask (RRP £599), only offer 35mW/cm², which is not nearly enough to deliver these results
As Dr. Mitchell points out, “LED face masks are more of a gimmick and are not value for money when compared to more powerful devices.”
The Solis Spectrum SOLO, currently priced at £299 (down from £399), offers far superior power output at a more affordable cost, ensuring that you get the full benefits of red light therapy.
2. Reduces Inflammation, Pain, and Improves Joint Health
Red light therapy has proven anti-inflammatory properties that can help relieve pain and improve joint health.
This is particularly beneficial for those suffering from arthritis, tendonitis, or other chronic inflammatory conditions.
A meta-analysis published in The Lancet found that red light therapy significantly reduced pain and stiffness in patients with rheumatoid arthritis.
Additionally, research in Photomedicine and Laser Surgery demonstrated reduced knee osteoarthritis pain and improved joint flexibility.
“For many, it’s a natural way to manage pain without relying on medications which can come with nasty side-effects” says Dr. Mitchell.

3. Improves Sleep Quality
Struggling with sleep? Red light therapy might help you catch more restful Z’s.
Red light exposure has been shown to regulate circadian rhythms, helping improve both the quality and duration of sleep.
A study in the Journal of Athletic Training found that athletes who used red light therapy before bed experienced improved sleep duration and quality.
Dr. Mitchell suggests that both the therapy’s calming effects and its boost in melatonin levels can help people fall asleep faster and wake up feeling more refreshed.

4. Supports Hair Growth and Prevents Hair Loss
Hair loss affects millions of people worldwide, but red light therapy offers a potential solution.
By stimulating hair follicles, it can promote regrowth in individuals suffering from androgenetic alopecia.
A study published in Lasers in Surgery and Medicine confirmed significant improvements in hair density after regular red light therapy use.
Dr. Mitchell points out, “The light promotes increased blood circulation and oxygen to the scalp, which can activate hair follicles and encourage new growth.”
However, it’s crucial to use a medical-grade device with adequate power.
Red light therapy helmets and hats, often seen online, generally lack the necessary irradiance to be effective.
In contrast, devices from the Solis Spectrum range offer superior power and coverage, making them a far better investment for those serious about reversing hair loss and supporting new growth.

5. Accelerates Muscle Recovery and Reduces Soreness
Athletes and fitness enthusiasts have increasingly turned to red light therapy to speed up muscle recovery and reduce post-exercise soreness.
A study in the American Journal of Physical Medicine & Rehabilitation found that participants who used red light therapy post-exercise experienced reduced muscle soreness and faster recovery times.
“It works by increasing circulation and oxygenation in muscle tissue, which helps repair and regenerate damaged cells,” Dr. Mitchell explains.
Interestingly, red light therapy has been proven more effective than cold therapy, such as ice baths, in boosting recovery and enhancing exercise performance.
While ice baths may help reduce immediate inflammation, red light therapy goes further by promoting deeper muscle healing and reducing delayed onset muscle soreness (DOMS).

6. Boosts Mood and Reduces Depression
Red light therapy is not just for the body; it’s also for the mind.
It's being explored as a treatment for mood disorders, such as seasonal affective disorder (SAD).
A study published in the Journal of Affective Disorders found that red light exposure led to a significant reduction in depressive symptoms.
According to Dr. Mitchell, “Think of how great you feel in the sun? Well, red light therapy harnesses the same mechanism as the sun to help increase serotonin production, which is often called the ‘happy hormone,’ leading to improved mood and reduced feelings of depression.”

7. Promotes Wound Healing and Tissue Repair
Red light therapy can accelerate wound healing and tissue repair by enhancing cellular regeneration and reducing inflammation.
Research published in the Journal of Clinical and Experimental Dermatology Research supports its use for faster recovery from wounds, cuts, and surgical incisions.
“The therapy increases circulation and collagen production, two key factors in the healing process,” notes Dr. Mitchell.

8. Aids Weight Loss and Boosts Metabolism
Some research indicates that red light therapy may assist with weight loss by reducing body fat and boosting metabolism.
A study published in the Journal of Obesity Surgery found that participants who used red light therapy experienced greater fat loss and a noticeable reduction in waist circumference compared to a control group.
Dr. Mitchell explains, “Red light therapy may help break down fat cells and increase metabolic rate, making it easier for the body to burn calories and eliminate fat.”

9. Supports Hormonal Health and Fertility
Hormonal health is a crucial aspect of overall wellness, and red light therapy can play a significant role in balancing hormone levels.
For men, studies have shown that it can boost testosterone levels, which is particularly important given that testosterone levels have been dropping at an alarming rate over the past 20-30 years, negatively impacting fertility and overall vitality.
In women, red light therapy may help regulate hormones such as estrogen and support thyroid function, potentially alleviating symptoms of menopause and menstrual irregularities.
Additionally, it has been linked to improved fertility outcomes in both men and women.
A study published in Endocrine Reviews explored these hormonal benefits, showing potential for improving both male and female fertility by enhancing sperm quality and supporting ovarian function.

10. Enhances Cognitive Function and Improves Recovery From Brain Injury
Emerging research suggests that red light therapy could enhance cognitive function, particularly in older adults or those with cognitive impairments.
A study in Ageing and Disease found significant improvements in memory, attention, and overall cognitive performance with regular red light therapy sessions.
“This therapy could potentially slow down cognitive decline and improve brain health,” states Dr. Mitchell.
