What Are The Benefits Of Blue Light Therapy?

In recent years there has been an increase in the use of blue light waves for treating several skin conditions and disorders. Blue light therapy is a painless, minimally invasive procedure that is regularly used by dermatologists for skin repair and rejuvenation, and it is also a standard treatment for specific medical issues.

What Is Blue Light Therapy?

Blue light therapy, also known as photodynamic therapy, is a procedure that uses a combination of photosensitizing agents (specialized drugs) and wavelengths of blue light, to treat various conditions. Depending on the part of the body being treated, the photosensitizing agent will be put on the skin, or infused via a vein into the blood stream. These drugs only take effect when they are activated by the blue light therapy. At Skin Cancer Specialists, we use the photosensitizing agent known as Levulan to treat pre-cancerous lesions.


Blue light therapy can be safely used to treat a range of conditions including the following:

Pre-Cancerous Lesions

Blue light therapy is used to treat pre-cancerous lesions known as Actinic Keratosis (AK), a skin condition that can potentially develop into cancer.

How It Works

The photosensitizing drug Levulan is first administered and is left in place for about 60 minutes. The blue light is then directed on to the skin activating the medication resulting in the destruction of specific cells, particularly pre-cancerous cells. People who undergo blue light therapy for pre-cancerous lesions generally experience very good results. In most cases the therapy is able to completely clear the lesion.

Skin Repair

Blue light therapy is commonly used for ‘off-label’ uses to treat a variety of skin conditions such as acne, psoriasis and rosacea. It can also be used to treat sun damage, and reduce the appearance of wrinkles and fine lines.

Acne Treatment

Blue light therapy is an additional option for the treatment of acne, and is frequently selected in place of topical and oral medications. Blue light successfully destroys the p. acnes bacteria within the follicles that cause inflammation. The blue light penetrates into the oil glands in the skin targeting the bacteria sensitive to the light, and also reducing the size of the oil glands. After treatment there will be a significant reduction in the amount of oil and bacteria in the skin. Consequently there will be less inflammation and fewer pimples, resulting in an overall improvement in the appearance of the treated areas of the skin. Blue light therapy has been proven to help acne patients achieve better skin, as it also helps with acne scars. It is especially beneficial for people with inflammatory acne. Blue light therapy can be used to treat mild to severe acne, and is suitable for most skin tones.

Aging Skin

Blue light therapy also offers multiple benefits for the skin and can be used to revitalize aging skin, by reducing fine lines and wrinkles. Blue light helps to promote the production of collagen and elastin which are vital proteins that help to support the underlying structure of the skin. As more collagen is produced over time, the skin will become tighter and younger looking. Blue light therapy also significantly improves skin quality. Blue light can also be used in conjunction with anti-aging ingredients such as antioxidants, retinoids and peptides. It helps to enhance the absorption of skin nutrients at the cellular level.

Is Blue Light Therapy Safe?

Blue light therapy is generally considered a safe procedure when administered by medical professionals with the required training. The light must be applied at the correct dosage and timing for optimal effect, and the eyes must also be protected with goggles. Side effects of treatment are usually minor and may include swelling at the treatment site, as well as dryness. If you reside in or around the greater Atlanta metro area, contact Skin Cancer Specialists, P.C. & Aesthetic Center, to find out more about our Blue Light therapy treatments.
