Blue Light Therapy For Acne

While there is not enough evidence yet that blue light therapy is more effective for acne compared to topical retinoids, the Food and Drug Administration (FDA) approved this treatment for acne vulgaris that has not been responsive to other products or therapies. As aforementioned, some relevant studies have also proven blue light therapy to be effective in managing acne. If you want to try this treatment, it is also 100% safe because it is free from UV rays, and has little to no side effects.

Does Blue Light Therapy Work for Acne?

Blue light therapies show promising results in treating acne. According to the American Academy of Dermatology (AAD), most people who have undergone this treatment reported significant improvement in their skin. A little disclaimer though, results still vary per person and according to the severity of the condition.

Several studies prove the benefits of blue light therapy for acne. In a 2004 study, 28 adults with facial acne went through 8 sessions of blue light therapy. After 4 weeks, they experienced 65% improvement in their acne lesions.

In a 2011 study, 90% of the participants with mild-to-moderate acne experienced improvements in their overall skin appearance after self-administering blue light therapies. They also favoured this treatment because it was gentler than other acne treatments.

Benefits of Blue Light Therapy

According to experts, blue light is helpful for acne because it produces oxygen that destroys the P. acnes bacteria. They also have anti-inflammatory benefits, and reduce the appearance of inflamed acne lesions.

Compared to other acne treatments, blue light therapy is more beneficial because of the following:

  • It is unlikely to produce complications.
  • It is safe for all skin types.
  • It can be used with other acne therapies and skincare products.
  • Aside from the face, it can also be used on other areas of the body.
  • It’s safer because it does not involve antibiotics.
  • It reduces sebum production and fights acne causing bacteria.
  • It is gentler to the skin, improves overall appearance, and does not cause scarring.
  • It cleanses the skin while healing injured tissues.

Effects and Risks of Blue Light Therapy

The American Academy of Dermatology approves light therapy as a generally safe treatment. It does not have any long-term and serious effects.

However, some minor adverse effects may still be present. This may include dry skin, itchiness and irritation, changes in skin colour, and stinging. But these will usually go away after your treatment.

It is also worth noting that you should not undergo light therapy if you are using any product that makes your skin sensitive to light.
