OVERVIEW Blue light therapy is used in the treatment of mild to moderate acne. It can be recommended for those who have not responded to other acne treatments and is usually administered over a number of weeks. Blue Light Therapy can be carried out in a salon/clinic and there are also home kits available to purchase. Other acne treatments include prescription creams, antibiotics, IPL acne treatment and chemical peels.
Acne blue light therapy works by targeting the bacteria that cause acne. Blue light kills these acne-causing bacteria known as Propionibacterium acnes, or P acnes, which can cause inflammation. P acnes is sensitive to blue light which eliminates the bacteria found in the oil glands in the skin.
What to Expect
Before exposing your skin to the blue light, your practitioner may apply a special medication designed to make your skin more sensitive to light (photosensitiser). The blue light treatment may also be used in combination with red light.
Users should see a visible improvement in terms of reduced inflammation and clearer skin within 4 weeks. After 12 weeks improvements should be significant.
Acne blue light therapy is rarely seen to cause side effects, and is not known to damage skin but some users may experience redness, soreness and peeling. The acne may get worse before it gets better.
