Red Light Therapy for Acne: A Revolutionary Treatment Backed by Clinical Studies

Introduction

In recent years, red light therapy has emerged as a groundbreaking treatment for various skin conditions, including acne. This non-invasive and painless therapy utilises specific wavelengths of red light; blue light and NIR light to target acne-causing bacteria, reduce inflammation, and promote skin healing. If you’re tired of battling acne with conventional chemical based treatments, it’s time to explore the potential of red light therapy for acne. In this comprehensive guide, we’ll delve into the science behind red light therapy and its efficacy in treating acne, supported by references to evidence based clinical studies. There is a lot of noise in this space and it is so important to rely on solid science backed evidence when considering the appropriate products and wavelengths to use.

Understanding Acne


Before we delve into the benefits of red light therapy, it is important to understand what acne is and what causes it. Acne is a skin condition that occurs when hair follicles become clogged with oil, dead skin cells, and bacteria. This can result in the formation of pimples, blackheads, whiteheads, and even cysts. Acne is often influenced by hormonal changes, such as those that occur during puberty, but it can affect people of all ages.

What is Red Light Therapy?

Understanding the Basics of Red Light Therapy

Red light therapy, also known as low-level light therapy or photobiomodulation, involves exposing the skin to specific wavelengths of red light. These wavelengths penetrate deep into the skin and stimulate cellular activity. When applied to the skin, red light therapy helps to increase blood circulation, reduce inflammation, and promote healing. It also stimulates the production of collagen, a protein that is essential for maintaining healthy and youthful-looking skin. Please watch this great video explainer for a deeper understanding.

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.

  • 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. It is further reported to control the condition before an outbreak occurs. This blue light therapy is clinically shown to control acne without harsh chemicals or prescriptions and improves the skin’s appearance.It has been shown both in vivo and clinically that acne may be treated successfully with blue visible light phototherapy.
