Red Light Therapy Pros and Cons

✓ Medically Reviewed by Jack Cincotta

With thousands of studies on red light therapy it is a simple task to demonstrate both the pros and cons of using red light therapy.

What is Red Light Therapy and How Does it Work?

Red light therapy, sometimes referred to as Low Level Laser Therapy (LLLT) has gained popularity in recent years as wellness and health conscience individuals harness its power for their greater benefit. Red light therapy works by activating our cells and mitochondria which speeds up healing, fat loss and improves sleep.

Red light therapy is the administration of red and near infrared light to our bodies and cells for the benefit of healing and recovery. Countless studies have highlighted the benefits of red light therapy for humans. 

When you have a red-light therapy session the warmth you feel is from the infrared light and the red color you see is from the red LEDs. The best frequencies of red light to use are found between 630nm and 660nm. The most effective near infrared light frequencies are located at 850nm on the electromagnetic spectrum.

By activating cytochrome c-oxidase at the fourth phase of electron chain transport, red light therapy has been shown to stimulate more efficient energy production. Adenosine triphosphate (ATP) is produced at a cellular level and is enhanced by red light therapy assisting the freeing up to oxygen atoms by reacting with nitric oxide.

When energy production is more efficient it allows our cells to restore, rejuvenate and repair easier. This helps with a lot of conditions such as hair loss, medically diagnosed mild arthritis and acne.

Red Light Therapy Pros 

Red light therapy comes with incredible benefits. We have listed the best benefits below.

Health Benefits – Red light therapy has been shown to be an effective treatment for a wide range of health conditions. Always ensure you have your medical conditions medically diagnosed first. Red Light Therapy has been shown to improve skin conditions (excluding skin cancer), hair growth, collagen production, morning stiffness, wound healing medically diagnosed mild arthritis, sleep and recovery. 

Convenient – Red light therapy can be used in the comfort of your own home. Gone are the days of having to pay tens of thousands of dollars per year to use red light therapy in a salon. Today you can purchase small handheld panels all the way up to large full body modular panels depending on your requirements. Red light therapy at home is great for skin rejuvenation (activating skin cells), seasonal affective disorder (SAD) and improved blood flow.

Backed by Clinical Research - Red light therapy has been shown in over 4,000 clinical trials and academic studies to be safe, effective and benefit humankind. When you look for additions to your wellness routine it’s always a great idea to ensure the products you use are not only backed by science but registered as medical devices.

Red Light Therapy Cons 

Before embarking on your journey into red light therapy it is paramount to assess the downsides. there can be some negative effects of red light therapy to consider.

Photosensitivity – Some people report having irritated skin when using red light therapy. When you first get your red light therapy device you can perform a light sensitivity test to see if you have a reaction to red light panels. You should always seek medical advice before using red light therapy devices for the first time from your doctor or physician. 

Inefficient Machines – Not all red light therapy devices are created equal and it can be hard to see which are backed by science and which are not. Many companies sell red light therapy panels that are better used for plants. Also, inflated irradiance reports are commonplace where companies can inflate the power and efficacy of their panels which can be misleading. We would always recommend partnering with a brand that has high irradiance panels and has them registered as medical devices.

Not Registered as Therapeutic Goods – Many brands do not have their red-light panels registered with the Australian Register of therapeutic Goods or the FDA in the USA. BON CHARGE has both registrations for our red light therapy machines. If the panel you are buying does not have medical device status, then you risk purchasing a device that may not complies with Australian or American safety and efficacy standard.

We always recommend asking the company you purchase from to show you that their red-light devices are registered with the relevant medical governing bodies.

Electrical Safety Concerns – The majority of red-light devices on the market may not have been tested to high quality electrical standards. This can render your device unsafe for use. Unsure that your device as electrical safety certification and is registered as “electrically safe”. BON CHARGE has ensured all their applicable red light panels have been entered into the EESS database and hold SAA electrical safety certification.

Non-standardised – Whilst clinical trials have shown what wavelengths of red light are beneficial to human health this isn’t always what is found in red light therapy devices. As the field is not fully regulated it means some cheaper red-light machines may not provide the most beneficial frequencies of light. They may not have even been tested to see what frequencies of red light they emit.
