What Is It?

Laser therapy is thought to work by inhibiting the activity of skin oil (sebaceous) glands, killing acne bacteria, and reducing inflammation.


Strength of Evidence
Average 67% reduction in acne after 3 - 8 sessions

Side Effects

Medium-high side effects and adverse reactions's Real World Take

Laser therapy works by harming skin oil glands. That can lead to some improvement in acne, and perhaps even long-term relief of some acne symptoms. However, evolution gave us skin oil glands for a reason and what happens long term when you permanently disable them is still unknown. Proceed with caution.
