EXPERT Q&A

Q: How is Blue Light used to treat acne? Are there other treatments for acne?

What our experts say:

Blue light is 420 nanometers in the light spectrum which is an antibacterial light. Bacteria have a chemical that the blue light absorbs into. They go through a conversion that disintegrates, or kills, the bacteria.  When you decrease bacteria, you decrease the inflammation that contributes to getting pimples. We use it adjunct with other treatments. It’s a weekly treatment, for four to six weeks in a row; and then they come back every once in a while. It calms the bacteria down. There is also a laser treatment, Isolaz, which is a combination of mechanical suction and light. It has a handpiece with a lamp at the end and a suction face, and you can vary the strength of the suction. You place it on the skin and it sucks the skin into the device; so pores are forced to be squeezed. At the same time, it shines blue, red and infrared light and that combination is great.  The blue light decreases bacteria, the red light decreases inflammation, and the infrared light is used for heating purposes which contributes to the detriment of the bacteria. It’s a very special machine that a lot of patients like a lot because they get a mechanical facial.  You can also use microdermabrasion to treat acne, which should be powder free. The DiamondTome machine has a handpiece encrusted with different sizes, or grids, of raw diamonds. We vary the suction according to what you want accomplish.  Dermasweep, is another microdermabrasion device that has brushes you can attach to the handpiece from soft to metal brushes. You can also attach an IV bag of an active ingredient (like salicylic or glycolic acid, or vitamin C) to splash on the skin at the same time. Not only does the patient get a microdermabrasion treatment, but they are also getting an ingredient into their skin according to what their skin needs.
