Red Light Therapy: Should it have a Green Light?

Red Light Therapy: Should it have a Green light? Here in Brentwood, TN the buzz about Red light therapy (RLT) has been growing. Patients often come into our office asking about the seemingly magical treatment that promises everything from skin rejuvenation to pain control. However, as physicians, it's our duty to shed light on the realities behind the hype. Today we will dive into some common misconceptions and overreaches of Red Light Therapy (RLT).

The Allure of Red Light Therapy

Therapy known as, photobiomodulation, involves exposing the skin to low levels of red or near infrared light. Proponents claim it can reduce signs of aging, heal wounds faster, alleviate pain, treat acne, rosacea and even promote hair growth, but how much of this is backed by solid science? 

Misconceptions and overreaches

• Universal Suitability: One of the biggest misconceptions is that RLT is a ‘one size fits all’ treatment, however, not everyone will respond the same way to this therapy given the numerous variations in skin type, health conditions and individual biological responsiveness.
• Miracle Cure: While some studies suggest benefits, the leap to calling RLT a cure for a wide array of conditions is an overreach as the evidence is often from small scale, small term studies which can be misleading when extrapolated to broader populations or long term effectiveness.
• Lack of Reproducible Results: A critical point that is often missed is that many positive studies have not been replicated on a larger scale or over extended periods. Without affirmation through replication, we cannot confidently assert that the benefits observed will hold true across diverse groups.

In addition, the Cleveland Clinic, a respected name in medical research, has also weighed in on RLT recently. According to their publications, while there's intrigue and some promising data, the evidence for many of the RLT's touted benefits remain inconclusive, unsubstantiated without replicated studies and lack statistically significant findings.  They state, RLT's true potential will need to be examined with large, randomized, placebo-controlled trials to fully understand RLT’s true potential and possible limitations. 

The Placebo Effect

One of the concerns with treatment that are reported to have no adverse effects is the potential for a strong placebo effect.  If therapy does not produce adverse reactions, it can be challenging to differentiate whether the perceived benefits are due to treatment itself or merely the patient's belief in its efficacy. This aspect requires cautious interpretation of study results. 

Who Should Be Cautious?

Patients with certain conditions including, but not limited to, those with light sensitive conditions or those on photosynthesizing medications should approach RLT with caution. Those with dark pigmentation should also be aware that certain conditions, including melasma, may in fact worsen with certain light therapy. Those who are pregnant may avoid RLT as there's insufficient data on the effects of RLT during pregnancy, making it a wise time to avoid until more is known.  Also cancer patients should be cautious, although some early research suggesting no promotion of cancer growth with RLT, the field is not conclusive.

Here at Nashville Dermatology Physicians in Brentwood, TN both Dr. Jeffrey Berti and Dr. Toula Berti are always looking for innovative treatments to offer our patients. We are excited to continue evaluating the promises of Red Light Therapy, however, we must remain skeptical, as well as informed. While there are hints of potential health benefits, the science isn't green lighted just yet. RLT might have a place in dermatology, but it's probably not the panacea it's sometimes advertised to be. More research is crucial and until we have more definitive answers, let's treat this therapy with a healthy dose of skepticism rather than giving it an automatic green light!
