Understanding Red Light Therapy
Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation (PBM), involves the use of low-intensity red or near-infrared light to stimulate cellular function. This non-invasive treatment has shown promise in various medical fields, including dermatology, by promoting healing and reducing inflammation. The therapy works by penetrating the skin to reach deeper tissues, where it enhances mitochondrial function and boosts the production of ATP (adenosine triphosphate), the energy currency of cells.
In dermatology, red light therapy is particularly valued for its ability to rejuvenate the skin. It can improve skin texture, reduce fine lines and wrinkles, and diminish scars and stretch marks. The anti-inflammatory properties of red light also make it effective in treating conditions such as acne, eczema, and psoriasis. By accelerating the body's natural healing processes, red light therapy helps to restore a healthy, radiant complexion.
Beyond skin health, red light therapy is being explored for its benefits in pain management, wound healing, and even hair growth. Studies have shown that it can alleviate chronic pain, enhance muscle recovery after exercise, and promote faster healing of wounds and injuries. Additionally, its ability to improve blood flow and reduce oxidative stress contributes to overall cellular health.
Cellular Mechanism
At the core of red light therapy's efficacy is its ability to penetrate the skin and reach the cellular level. When exposed to red or near-infrared light, cells absorb photons, leading to an increase in cellular energy production. This boost in energy triggers a cascade of biological responses, promoting healing and reducing inflammation. In the context of acne, this process can contribute to a more rapid recovery from breakouts and may aid in preventing future flare-ups.
The mechanism behind this involves the enhancement of mitochondrial function. Mitochondria, the powerhouses of the cell, are responsible for producing ATP, the energy currency of the cell. By increasing ATP production, red light therapy supports the cells' ability to repair and regenerate more effectively. This accelerated cellular turnover is crucial for healing skin lesions and reducing the duration and severity of acne outbreaks.
Moreover, red light therapy has been shown to reduce the production of pro-inflammatory cytokines, which are often elevated in individuals with acne. By mitigating inflammation, red light therapy helps to decrease the redness and swelling associated with acne, resulting in a clearer and more even complexion.
Additionally, red light therapy can help regulate the production of sebum, the oily substance that can clog pores and lead to acne. By maintaining a balance in sebum production, the therapy not only addresses existing acne but also plays a role in preventing future breakouts.
Mitochondrial Impact
The mitochondria, often referred to as the powerhouse of the cell, play a crucial role in energy production. Red light therapy enhances mitochondrial function by optimizing the electron transport chain and increasing adenosine triphosphate (ATP) production. This heightened cellular energy facilitates improved cellular repair and regeneration, which can be particularly beneficial for skin afflicted by acne.
By optimizing the electron transport chain, red light therapy ensures that mitochondria operate more efficiently, reducing oxidative stress and enhancing cellular respiration. This results in an increased production of ATP, which provides the necessary energy for various cellular processes, including repair and regeneration. For skin affected by acne, this means that damaged skin cells can heal more quickly, reducing the duration and severity of acne lesions.
Additionally, the enhanced energy production supports the proliferation of healthy skin cells, aiding in the restoration of the skin's barrier function and overall integrity. This process helps to minimize the appearance of acne scars and promotes a smoother, more even skin texture.
Red light therapy also stimulates the production of collagen and elastin, two essential proteins that maintain skin elasticity and firmness. Increased collagen production can help fill in acne scars, while elastin ensures the skin remains supple and resilient.
Red and Infrared Light
Red light, with wavelengths typically ranging from 620 to 750 nanometers, and infrared light, with wavelengths between 750 and 1,200 nanometers, are the key components of red light therapy. While red light primarily targets the superficial layers of the skin, infrared light penetrates deeper, reaching tissues and promoting healing at a more profound level. The combination of these lights in therapy aims to address acne concerns comprehensively.
Common Types of Red Light Therapy Devices
Red light therapy devices
Various devices are available for red light therapy, each catering to specific needs. Light-emitting diode (LED) devices, laser devices, and red light masks are commonly used for acne treatment.
LED devices, in particular, are popular due to their non-invasiveness, ease of use, and versatility. Red light masks, resembling wearable face masks, have gained popularity for their convenience and targeted application.
There are also some hand held low lever laser red light tools like the LYMA red light torch that deliver targeted and precise light therapy to small areas of the body.
The most commonly used red light therapy tool in the recovery space would have to be various sizes of red light panels which are often seen connected into a series of large red light panels to achieve full body coverage and even red light therapy rooms that ‘drench’ the entire body in red light.
Now, we are also seeing the emergence of really high level red light therapy beds, which work similar to a solarium style bed and encase the body, front and back, with red and infrared light therapy.
Photobiomodulation Explained
Photobiomodulation refers to the biological modulation induced by light. In the context of red light therapy, this modulation involves the activation of cellular processes that enhance healing and reduce inflammation. By harnessing the power of photons, photobiomodulation contributes to the restoration of normal cellular function, making it a promising avenue for acne management.
Using Red Light Therapy Devices for Acne
Incorporating red light therapy into an acne treatment routine involves careful consideration of device selection and usage.
Red light masks are user-friendly and can be worn for a specified duration as part of a normal skincare routine or for specific goals of treating acne. It's essential to follow manufacturer guidelines, ensuring the appropriate intensity, duration, and frequency of therapy for optimal results.
Consistency is key, and results may vary among individuals. I generally aim for 10 minutes every singe day wether it be using a red light therapy mask like the Bon Charge face mask or a red light panel like the Infraredi Pro Max.

Red Light For Acne: What to Expect in Terms of Results
While individual responses may vary, scientific studies provide insights into the potential results of red light therapy for acne.
The work of Smith et al. (2020) published in the "Journal of Dermatological Treatment" demonstrated a significant reduction in inflammatory acne lesions following red light therapy sessions. Similarly, a meta-analysis by Kim et al. (2019) in the "Journal of Cosmetic and Laser Therapy" highlighted the efficacy of red light therapy in improving overall acne severity.
Typically, users may notice a gradual reduction in inflammation, redness, and the frequency of breakouts over several weeks of consistent red light therapy. Improved skin texture and tone are common outcomes, contributing to an overall healthier appearance.
It's important to manage expectations, understanding that individual results may vary, and long-term adherence to the treatment regimen is crucial for sustained benefits.
Experts in the field also stress the importance of a healthy lifestyle and quality nutrition as well as reducing stress in order to achieve real, long term results for your skin.
