acne
"I'm 24 and have mild to moderate acne on my chin and red hyperpigmentation spots from old pimples. I've tried benzoyl peroxide and salicyicate acid, but this is more effective and also helps with hyperpigmentation from old acne. I also prefer not to take a pill (antibiotics, accutane) to treat acne. I was excited to find this over the counter. The first 3 days I used it, my acne got worse. Within a week, however, my pimples dried up. It is very effective. I gave 9/10 and not 10/10 because my face has been very dry, and sometimes it burns a little. This is a normal side effect I expect to get better with using it more. You can use this every other night if your skin gets too dry."
