Blue light treatment is an acne treatment that works by
targeting and eliminating acne-causing bacteria on your skin. The specific

There’s no downtime from blue light treatment,
but you may have some temporary minor discomfort. Most dermatologists will
recommend multiple blue light treatments for optimal results. The amount of sessions
you’ll need can vary, but about six sessions once or twice a week is common.
