What to Expect during Blue Light Therapy

Blue light therapy is a non-invasive acne treatment that uses a high-intensity light source to kill the bacteria that causes breakouts. The procedure can treat moderate to severe cases of acne. Here are some things to expect if you choose to pursue the treatment.


Blue Light therapy by itself requires no specific preparation. Sometimes patients with more severe acne use the treatment in combination with a skin sensitizer that enhances the results. If you choose to use this method of treatment, your doctor will apply the sensitizer to the targeted areas an hour before the light therapy.

The Procedure

Each treatment session lasts anywhere from 15 to 30 minutes. During the session you will sit in a chair while the doctor administers the light to the treatment site. You may experience slight discomfort during the procedure.

Side Effects and Recovery

Blue Light therapy requires no down time. You may resume normal activities immediately after the procedure. You may experience swelling, dry skin, mild burning or discoloration of the treatment site. However, these side effects should subside within a few days. If you use the photo-sensitizing agent, you should avoid sun exposure for at least 48 hours following the treatment.

Results and Maintenance

After the treatment, you may notice fewer breakouts. Blue Light therapy also treats dark circles and increases the skin's elasticity. Some patients will notice results after just 1 session, while others may require several sessions to achieve their desired results. The treatment is not a permanent solution and will require regular maintenance. Results may last up to 4 months, depending on the type of treatment and the severity of the condition.
