Addressing Acne with Red Light Therapy

Reduction in Inflammation
One of the primary benefits of red light therapy for acne is its ability to reduce inflammation. The red light wavelengths have anti-inflammatory properties that can help calm the skin and reduce redness associated with acne. By decreasing inflammation, red light therapy can also alleviate pain and discomfort caused by acne breakouts.
Killing of Bacteria
Acne is often caused by the presence of bacteria on the skin. Red light therapy has been found to have antibacterial properties, making it effective in killing the bacteria that contribute to acne development. Blue Light also targets and destroys these bacteria and light therapy helps prevent new acne breakouts and promotes clearer skin.
Minimised Oil Production
Excessive oil production is a common factor in acne development. Red light therapy has been shown to regulate sebum production, the oil naturally produced by the skin. By reducing oil production, red light therapy helps keep the pores clear and minimises the likelihood of clogged follicles, leading to fewer acne breakouts.
Accelerated Healing
Another significant benefit of red light therapy is its ability to accelerate the healing process. The red and NIR light wavelengths penetrate the skin, reaching the deeper layers where the acne lesions originate. This stimulates the production of new cells, increasing collagen; helping to repair damaged skin and promote faster healing of acne scars.

Clinical Studies on Red Light Therapy for Acne

  • Study 1: Summary : Significant progress has been made so far in light-based treatment of acne. The strongest evidence for efficacy of light-based therapies for acne is for blue and blue-red light, with the greatest effect on mild to moderate inflammatory acne lesions. There is also evidence that PDT is effective in treating inflammatory acne lesions, although the adverse effects, mostly short term and self-resolving, tend to be more severe than blue light. “Light-based therapies in acne treatment”.
  • Study 2: Summary : The present study has shown that treating acne with both MAL-PDT and red-light-only PDT under an altered treatment regime of 20 J/cm2 after a 1.5 h occlusion time could be a good treatment modality, achieving an effect that can last for 20 weeks with tolerable side effects “Optimizing treatment of acne with photodynamic therapy (PDT) to achieve long-term remission and reduce side effects. A prospective randomized controlled trial“.
  • Study 3: Summary : Our study showed that LLLT using 630-nm laser (red spectrum) significantly reduces active acne lesions after 12 sessions of treatment during 10 weeks follow-up. “Comparison of Red and Infrared Low-level Laser Therapy in the Treatment of Acne Vulgaris“.
  • Study 4: Summary : It has also been proven that phototherapy can significantly affect the activity of sebaceous glands and reduce the keratosis of the hair follicles outlets.Li et al conducted a study on the biological effect of red LED radiation in acne, using an in vitro model and obtained normalization of keratinization within the sebaceous glands. In turn, Jung et al used light-emitting diodes (LEDs) emitting both blue (415nm) and red (630nm) light to verify their effect on lipid production in human sebaceous cells in vitro. They showed that blue light inhibits their proliferation and red radiation reduces lipid production, which is one of the acne pathogenetic factor. “The Anti-Acne Effect of Near-Infrared Low-Level Laser Therapy“.
  • Study 5: Summary : Phototherapy with visible light, specifically blue light, has been shown to improve skin condition in cases of acne and blemishes.

Red Light Therapy For Hair Growth

Increased Blood Circulation:
Red light therapy stimulates blood flow to the hair follicles. The red and near-infrared wavelengths of light penetrate the scalp and reach the hair follicles, promoting vasodilation and improving circulation. This increased blood flow delivers more nutrients and oxygen to the hair follicles, creating a conducive environment for hair growth. 
Activation of Hair Follicles:
Red light therapy can activate dormant hair follicles, coaxing them into the active growth phase (anagen phase). This process is particularly beneficial for individuals experiencing thinning hair or hair loss due to follicle inactivity.
Reduction of Inflammation:
Red light therapy has anti-inflammatory properties, which can help reduce scalp inflammation. Chronic inflammation in the scalp can contribute to hair loss, so reducing inflammation may support a healthier hair growth environment.
Enhanced Cell Metabolism:
The red light wavelengths can increase adenosine triphosphate (ATP) production in cells. ATP is a molecule responsible for energy transfer within cells, and higher ATP levels can enhance cell metabolism, including those of hair follicles, potentially promoting hair growth. Prolongation of Anagen Phase: Red light therapy may extend the duration of the anagen phase, which is the active growth phase of the hair cycle. A longer anagen phase means more time for hair to grow before transitioning to the resting (telogen) phase.
Thicker and Stronger Hair:
Some studies suggest that red light therapy may lead to thicker and stronger hair by enhancing hair shaft quality and

Clinical Studies on Red Light Therapy For Hair Growth

Michael R. Hamblin traces the connection of red light therapy and hair loss to a time over 50 years ago when Mester in Hungary observed regrowth of hair in mice when irradiated with a ruby laser [8].
Today more studies prove that red and NIR light therapy is effective in hair growth. The following are examples of these studies:
A study in 2018 [9] reviewed available literature on the use of red and NIR light for hair loss. The researchers proved that light in the red spectrum is effective for hair growth.
A study conducted in Korea published in 2020 determined the safety and efficacy of red light therapy in the treatment of alopecia. The results of meta-analysis showed that red light therapy has an efficacy on alopecia. Moreover, there were no serious side effects or adverse effects observed.
In 2013, years before these confirmatory studies, a pioneering study [11] researched on the safety and physiologic effects of red light therapy on males with androgenic alopecia. Results showed that red light therapy of the scalp at 655 nanometers significantly improved hair counts in males with androgenetic alopecia.
A similar study [12] was conducted, this time to female subjects, in 2014. Results have shown that red light therapy of the scalp at 655 nanometers significantly improved hair counts in women with androgenetic alopecia at a rate similar to that observed in males using the same parameters.
It is also important to note that on both pioneering studies with men in 2013 and women in 2014, no serious side effects or adverse effects had been observed.
In 2017, a similar study [13] was again conducted among women with androgenetic alopecia. This time, the human hair follicle and surrounding tissue structures are exposed to laser light using a device operating at 650 nanometers. The device was placed inside a sports cap to promote discretion while in use. The researchers observed significant increase in hair growth among the test subjects.

Red Light Therapy For Anti-Aging

Collagen Production:
Red light therapy has been shown to stimulate fibroblasts, the cells responsible for producing collagen. Collagen is a crucial protein that provides structural support to the skin, maintaining its firmness and elasticity. By promoting collagen production, red light therapy can help reduce the appearance of fine lines and wrinkles, giving the skin a more youthful and plump appearance.
Wrinkle Reduction:
As the skin ages, it can develop wrinkles and fine lines due to decreased collagen levels and other factors. Red light therapy’s ability to boost collagen production, as well as improve blood circulation and tissue repair, may contribute to reducing the depth and visibility of wrinkles.
Improved Skin Texture:
Red light therapy can enhance skin texture by promoting the turnover of skin cells. It helps exfoliate dead skin cells and encourages the growth of newer, healthier skin cells, leading to a smoother and more even skin tone.
Increased Blood Circulation:
Red light therapy enhances blood flow to the skin, bringing with it more oxygen and nutrients. This improved circulation can rejuvenate the skin and promote a healthy, glowing complexion.
Enhanced Wound Healing:
Red light therapy may aid in repairing sun-damaged skin by stimulating cellular repair processes and reducing inflammation. It can also help fade dark spots and hyperpigmentation caused by prolonged sun exposure.
Decreased Inflammation:
Chronic inflammation can contribute to premature aging of the skin. Red light therapy’s anti-inflammatory properties can help reduce skin inflammation, leading to a calmer and more balanced complexion.
Non-Invasive and Painless:
Red light therapy is a non-invasive and painless procedure, making it a safe and comfortable option for individuals seeking anti-aging treatments without the need for surgical interventions.

Clinical Studies on Red Light Therapy For Anti-Aging

A 2014 study [12] established the safety and efficacy of red light therapy with a focus on pleasant skin feeling, improved skin appearance, intradermal collagen increase, and the visible reduction of fine lines and wrinkles in a prospective, randomized, controlled trial that consisted of 136 volunteers.
Another study [13] conducted in 2018 revealed that red light therapy stimulates fibroblast proliferation, collagen synthesis, growth factors, and extracellular matrix production by activating cellular mitochondrial respiratory pathways. The result is lifting and tightening lax skin and the reduction of rhytids.
Still another study conducted in 2009 investigated on the use of 660 nanometers of red light to reverse the downregulation in collagen synthesis and an elevation in matrix metalloproteinase (MMP) expression in the skin [14]. Results showed that red light therapy using 660 nanometers pulsed LED light is a safe and effective collagen-enhancement strategy.
In 2017, a study [15] also showed the effectiveness of red light therapy in collagen synthesis and in treatment of fine lines and wrinkles.
A 2013 study focusing solely on the effects of red light therapy in skin [16] demonstrated that red light therapy has beneficial effects on wrinkles, acne scars, hypertrophic scars, and healing of burns. It further established that red light therapy is effective even for pigmentary disorders such as vitiligo as well as in inflammatory diseases such as psoriasis and acne.
An earlier study in 2006 [17] on 36 subjects reported statistically significant improvement in wrinkles. The majority of the subjects reported improvements in softness, smoothness, and firmness of the skin after combined 633-nanometer and 830-nanometer light-emitting diode (LED) treatments.
These clinical and scientific studies on the effect of red light therapy to the synthesis of collagen in cells and tissues of the body in recent years prove the effectivity and efficiency of red light therapy for promoting healthy aging.

Red Light Therapy For Pain & inflammation

Analgesic Effect: Red light therapy can act as a natural analgesic, providing pain relief by blocking pain signals and reducing sensitivity to pain. It does so by modulating nerve cell activity and inhibiting pain transmitters.
Reduction of Inflammation: Red light therapy’s anti-inflammatory properties help to decrease inflammation in affected tissues. By reducing pro-inflammatory cytokines and promoting the release of anti-inflammatory molecules, it helps to mitigate the body’s inflammatory response.
Enhanced Blood Circulation: Red light therapy improves blood circulation in the treated area. This increased blood flow delivers more oxygen and nutrients to the tissues, promoting the body’s natural healing processes and reducing swelling.
Stimulated Cellular Repair: Red light therapy stimulates cellular repair and regeneration, which can aid in healing damaged tissues and reducing the duration of recovery.
Joint Pain Management: For conditions like osteoarthritis and rheumatoid arthritis, red light therapy has been found to alleviate joint pain and improve joint mobility.
Musculoskeletal Injuries: Red light therapy may accelerate the healing of sprains, strains, and other musculoskeletal injuries, providing pain relief and promoting tissue repair.
Back Pain Relief: Studies have shown that red light therapy can be effective in reducing chronic lower back pain, a prevalent issue that affects many individuals.
Sports Injuries: Athletes and active individuals may benefit from red light therapy for sports-related injuries, such as muscle strains or tendonitis.
Non-Invasive and Safe: Red light therapy is a non-invasive and safe treatment with minimal side effects, making it an attractive option for pain management without the use of medications or surgery.
Complementary Therapy: Red light therapy can be used as a complementary treatment alongside other modalities to enhance pain relief and inflammation reduction.

Approriate Wavelengths For Light Therapy Treatment

Understanding Joules: The Standard of Measurement for Professional Red Light Therapy 

Joules are the crucial unit of measurement in the realm of light therapy, specifically photobiomodulation. To put it simply, one Joule is equivalent to one Watt-Second. If 1W of light is directed onto a surface for 1 second, it results in 1 joule of power being delivered to that surface.

In the context of red light therapy (RLT), the dosage is typically around ten Joules per square centimeter (10J/cm²). This dosage is a key factor in determining the therapeutic effects and outcomes for patients undergoing professional red light therapy treatments.

When assessing RLT devices for professional use, it is vital to consider not only the wattage but also the light intensity values at various distances from the unit. The light output, measured in milliwatts per square centimeter (mW/cm²), is crucial in determining the dosage patients will receive during their treatment sessions.

For instance, let’s take the example of the Biocell 60 by Leredd. This unit has a 300-Watt rating but consumes only 110 Watts of power. Its light output is illustrated through graphs, showing that it emits light in both 660nm and 850nm wavelengths, which are commonly used in red light therapy.

For precise dosage calculations, it’s essential to know the power output in mW/cm² at different distances from the device. The Leredd Biocell 60 provides this information, making it easier for healthcare professionals to determine the appropriate exposure time for their patients.

Calculating the dosage is straightforward. By using the power output in mW/cm² and the desired dosage (in Joules), healthcare professionals can determine the required exposure time. For example, at 15cm away from the device, if the power level is 100mW/cm², it would take 10 seconds to deliver a 1J dosage. In 1 minute, a patient would receive a dosage of 6 Joules.

As the distance from the device increases, the power density decreases, which means longer exposure times are needed to achieve the desired dosage. Professional red light therapy treatments with specific dosage goals can be easily calculated using this formula.

For healthcare professionals seeking an even more convenient method, utilizing a smart dosage calculator can simplify the process significantly. Inputting the desired dosage and irradiance values into the calculator will yield the precise exposure time required to achieve the therapeutic dosage.

Red light therapy works by using specific wavelengths of red light to penetrate the skin and stimulate cells to produce more energy. This increased energy production can lead to a variety of benefits, such as reduced inflammation, improved circulation, and increased collagen production. The red light is thought to activate mitochondria, the powerhouses of cells, which then produce more ATP (adenosine triphosphate), the energy currency of cells. The increased ATP production can promote healing, reduce pain, and improve skin health.

Near-infrared light therapy works by using wavelengths of near-infrared light to penetrate the skin and interact with cells, promoting various biological processes. Near-infrared light can penetrate deeper into the body than red light and can increase blood flow, improve tissue oxygenation, and stimulate the production of nitric oxide, a molecule that helps to relax blood vessels and improve circulation. This therapy has been shown to have a range of potential benefits, such as reducing pain and inflammation, promoting wound healing, and improving cognitive function.

In general, safety goggles are not necessary for red light therapy because the wavelengths used in red light therapy are not harmful to the eyes. However, some manufacturers may recommend the use of goggles to protect against accidental exposure to brighter light sources or to reduce eye strain.

If you are using Near Infrared Light , it is recommended that you wear protective eyewear, such as goggles rated for use with lasers, to protect your eyes from potential damage. Additionally, if you have a history of eye problems or are concerned about your eye health, it is always best to consult with a healthcare professional before beginning any new therapy.
