About Blue Light Therapy

What is it?

Blue light therapy is a type of photodynamic therapy. Photodynamic therapy (PDT) is most commonly used to treat acne, but also can be used to treat a wide range of medical issues like cancer. Dr. Zimmet uses Blu-U Blue Light Therapy to treat his patients. During PDT, light-sensitive compounds, known as photosynthesizers, are exposed to light which causes a reaction. This reaction kills bacteria. For this minimally-invasive procedure, a photosynthesizer, which comes in the form of a liquid or gel, is applied to the skin.


What happens during a PDT treatment?

 After that, you must wait for 30-60 minutes for an incubation period. Following the incubation period, the targeted area will be exposed to the blue light for a predetermined amount of time. The light activates the photosynthesizer, which kills bacteria that can cause acne. Blu-U is not a laser. In fact, it is more comparable to a fluorescent light.

Are There Side-effects?

After the treatment, your skin will be quite sensitive to light, so it is very important to wear sunscreen and avoid going outdoors for one to two days. Because of the nature of blue light therapy, some patients will experience redness, dryness or a faint sunburn after treatment.

How Often are Treatments?

Specific courses of treatment will vary based on the doctor’s evaluation of your skin. Typical PDT treatments are usually scheduled once or twice per week for about five week.

Who Should Use it?

Blue light therapy is a good option for people with moderate acne, but who don’t want to use antibiotic or drug treatments.
