Blue Light Therapy for Acne

What is Blue Light Therapy?

Blue light therapy uses the power of light energy to treat a wide variety of skin conditions, such as acne. Blue light devices emit a narrow bandwidth of blue light that triggers different effects. For example, blue light kills the bacteria that cause acne. The treatment can also treat skin cancer lesions and skin damage from sun exposure.

How Does Blue Light Therapy Work?

Light rays from the sun travel in small waves, known as wavelengths. Scientists measure these wavelengths in nanometers (nm). The human eye can detect wavelengths of light measuring about 400 nm to 700 nm. At different wavelengths, light appears to have different colors. Light in wavelengths of 625 nm to 740 nm appears red, for example. Blue light wavelengths measure 435 nm to 500 nm.

Is Blue Light Therapy Safe?

The various wavelengths of light have different effects on the body. Red light stimulates the production of energy inside body cells, for example. Blue light has powerful anti-bacterial properties, making it an effective treatment for acne. The light in the blue wavelengths can also affect cancer cells. These effects make blue light a safe and effective treatment for a number of conditions.

BLU-U® Photodynamic Therapy

Skincare professionals sometimes apply a particular photosensitizing medication, known as Levulan, to the skin before administering blue light therapy. This procedure, known as BLU-U® photodynamic therapy, optimizes the benefits of blue light skin treatment. Once applied to the skin, oil glands absorb the Levulan; blue light activates the ingredients in Levulan. These activated ingredients destroy the cells in the oil glands, decrease oil production, and shrink the size of the oil glands.

While photodynamic therapy is more effective than blue light therapy alone, it can also cause more stinging, burning, redness and inflammation following treatment. Four treatment sessions performed every four weeks provide the best results.

Blue Light Therapy for Acne

Acne is a skin condition that can cause redness, swelling, and inflammation, which can also lead to scarring. Blue light therapy can help reduce the number of acne breakouts. It may also help reduce the size of pimples and the redness around them.

Blue Light Therapy for Fungal Acne

Fungal acne is a form of acne caused by yeast and other types of fungi. These growths can cause inflammation and redness in the skin. Blue light therapy is an effective treatment for fungal acne because it kills the fungi that cause the infection.

Blue Light Therapy for Hormonal Acne

Hormonal acne is a type of acne that occurs when hormone levels fluctuate. This can happen during puberty, pregnancy, menopause, and other times when hormone levels change. Because blue light destroys the bacteria that cause acne, it is an effective therapy for hormonal acne.

Blue Light Therapy for Cystic Acne

Cystic acne is a form of acne that occurs when the pores become clogged with oil and dead skin cells. This can cause the pores to become inflamed and infected, and blue light therapy kills the bacteria that causes acne.

Does Blue Light Help Acne Scars?

One of the major benefits of blue light therapy is that it can help to improve the appearance of acne scars. This is because the treatment helps to stimulate collagen production, which in turn can help to improve the appearance of scars. Additionally, blue light therapy can also help to reduce the redness and swelling associated with acne scars.

How Can Blue Light Therapy Help Acne?

Blue light therapy is a safe and effective treatment for acne. It can kill the bacteria that cause acne, reduce inflammation, and shrink the size of the oil glands. Blue light therapy is often used in combination with other treatments, such as photodynamic therapy, to optimize results. four treatment sessions performed every four weeks provide the best results.

Other Blue Light Therapy Benefits

Blue light treatment is comfortable and quick. Administered by a skincare professional, blue light therapy is also safe and highly effective. Blue light treatment is appropriate for a number of skin conditions, including different types of acne, skin damage, and even skin cancer. Blue light treatments work well alone or in combination with other types of treatments. This makes blue light therapy available to nearly everyone with a skin condition.

Blue Light Therapy for Sun Damage

Harmful ultraviolet (UV) rays from the sun can damage skin cells. Sun-damaged skin cells can turn into cancer cells and spread to the rest of the body. Blue light treatment kills these damaged cells before they can turn cancerous.

Blue Light Therapy for Skin Cancer

Skin doctors most commonly use blue light therapy to treat acne, but it is also effective in treating premalignant or malignant skin cancer growths, which are unhealthy skin cells that may turn into cancer someday. This treatment can prevent skin cancer and remove precancerous and cancerous skin lesions before they spread to other parts of the body.

In some cases, blue light treatment for skin cancer can help people with cancer live longer and improve their quality of life, according to the American Cancer Society. The photosynthesizing drug used in photodynamic therapy reacts with oxygen to kill cancer cells. This treatment can also stimulate the immune system, provoking the body’s natural response to cancer. This approach to blue light therapy can also damage the blood vessels feeding the cancer cells, effectively starving out cancer.

Are There Any Blue Light Therapy Side Effects?

There are almost no blue light therapy side effects, and any adverse reactions that do occur are typically temporary. Blue light therapy side effects may include red, swollen, tender, and mildly bruised or blistered skin in the treatment area. This is especially true following photodynamic therapy. In most cases, most people heal from these effects within seven days. The treated area may crust over or peel as the treatment destroys abnormal cells or affects oil glands. This normally resolves within three to 14 days.
