Reducing Acne

For individuals contemplating the use of red light therapy (RLT) as a treatment for acne, it’s important to understand the scientific basis of this approach, review relevant research findings, consider key factors before starting treatment, and reach a well-informed conclusion.

Scientific Basis

Red light therapy involves the use of specific wavelengths of red light, typically between 630 to 670 nanometers. The scientific premise for its effectiveness in treating acne lies in its anti-inflammatory properties and its ability to stimulate cellular repair and regeneration. Red light is believed to penetrate the skin and be absorbed by mitochondria, leading to enhanced cellular energy production. This increase in energy can boost cell function, which includes promoting healing and reducing inflammation, key factors in acne management. Additionally, RLT is thought to stimulate collagen production, which can help in healing acne scars.


The current research on RLT’s efficacy in treating acne includes:

  • Anti-Inflammatory Effects: Studies have shown that RLT can reduce inflammation, a critical component of acne.
  • Reducing Acne Lesions: Research indicates that RLT may be effective in reducing the number and severity of acne lesions.
  • Combination Treatments: Some studies suggest that RLT, when used in conjunction with other treatments like blue light therapy, can be more effective in treating acne.

Considerations Before Treatment

Before beginning RLT for acne treatment, it’s important to consider:

  • Consultation with Dermatologists: Professional advice is crucial, especially for individuals with severe or persistent acne.
  • Understanding the Research: Recognizing that while promising, research on RLT for acne is still developing, and its effectiveness can vary among individuals.
  • Skincare Routine: Integrating RLT into a broader skincare routine, as it may not be a standalone solution for acne.
  • Quality of Devices: Using medically-approved and effective RLT devices is important for safety and effectiveness.


Red light therapy presents a promising, non-invasive option for reducing acne, with scientific evidence supporting its potential efficacy in reducing inflammation and promoting skin healing. However, it’s important for individuals to approach this therapy with an understanding of the current research stage, in consultation with healthcare professionals, and as part of a comprehensive skincare approach. As research continues, the role of RLT in acne treatment and skincare may become clearer, offering a new method for managing this common skin condition.
