Ok, scratch hydrogen peroxide. It worked for about a week… then on my next breakout, I used it again for 2 weeks and the acne didn’t get any better. I stopped using it three days ago, and switched to tea tree instead, and the acne has already started to fade.
So, my mistake – hydrogen peroxide isn’t such a great idea for acne.
…But I have been using tea tree oil for years, and it still works!
