Acne Flare-ups: How Blue Light Can Clear Your Acne Lesions

If you suffer from acne, you’re probably always on the lookout for new treatments that might help improve your skin. You’ve probably tried a number of different creams, cleansers, and even prescription medications. But have you heard of blue light therapy? Blue light therapy is a treatment that uses light to kill acne-causing bacteria.

Acne is a common skin condition that can cause a lot of distress. There are many different treatments available, but one that is becoming increasingly popular is blue and red light therapy. This treatment uses light to kill acne-causing bacteria and reduce inflammation. Read on to find out how you can use blue and red light therapy to treat your acne.

How Does It Work?

Blue and red light therapy work by destroying the bacteria that cause acne and reducing inflammation. The blue light kills the bacteria, while the red light helps to reduce inflammation. This treatment is usually done in the skin specialist or dermatologist’s office with a special phototherapy device.

How Does Blue Light Therapy Work?

Acne occurs when the pores of your skin become clogged with dead skin cells debris and oil. This provides the perfect environment for bacteria to grow. When bacteria enters the pores, it causes inflammation and redness.

Acne bacteria produce an abundance of molecule called coproporphyrin-3. When acne is treated with blue light, the light targets the porphyrin molecule and causes it to break down and produce oxygen (free radical). Acne bacteria cannot survive in such an environment rich in oxygen and therefore the blue light kills the bacteria. Studies have shown that blue light treatment can be effective in reducing the number of acne lesions.

Is Blue Light Therapy Effective?

Studies have shown that blue light therapy can be an effective treatment for mild to moderate acne vulgaris—the most common type of acne. In one study, participants who received eight weeks of blue light therapy experienced a 50% reduction in their acne lesions. Their skin also had a decrease in sebum production (the oily substance that can contribute to clogged pores).

Is Blue Light Treatment Used Alone Or In Combination With Other Lights During The Therapy Session?

Infrared and red light are usually used in combination with blue light therapy to help minimize acne flare-ups by reducing inflammation and increasing circulation in the lesion areas. Combination therapy helps keep pores clean, allowing new healthy cells to replace damaged ones, resulting in a clearer skin and younger looking appearance.

When used together, blue, infrared, and red lights have been proven to be an effective treatment modality for reducing acne flare-ups. In some cases, the combination of light therapy can result in drastically reduced acne lesions and even prevent new ones from forming.

How Often Should One Use Blue Light Therapy?

Depending on the severity of your acne, you might need to use blue light therapy daily or just a few times a week. A typical session lasts about 15 to 20 minutes, but this can vary depending on the intensity of the light used and your individual response to treatment.

 Are There Any Side Effects?

One of the great things about blue light therapy is that there are very few side effects. The most common side effect is temporary redness or swelling immediately after treatment. You might also experience some dryness or scaling of the skin—but this is usually temporary and will resolve with continued use of the treatment.
