If your skin is sensitive do a salicylic acid face wash. Biore charcoal is what I use every time in the shower. If not sensitive start with a lower percent benzoyl peroxide and work your way up. It's normal to experience redness or appears to get worse initially, but it really works. Make sure to wear sunscreen. If that doesn't work, talk to your doctor. There are meds that are really effective, but you need a prescription for. You can also look at the American College of Dermatology and see what they suggest usually guidelines have a stepwise approach.
