I think we often overlook that even the best acne treatments can be problematic for many people. For example both salicylic acid and benzoyl peroxide can irritate your skin. And if something is irritating you’re going to be less likely to use which means it’s not going to work as well. Even prescription drugs that are effective can have serious consequences. For example tetracycline, if taken at too early an age, can actually permanently stain your teeth. And then there are a host of rumored tricks like putting toothpaste or Windex on pimples are simply not proven to work at all. The good news is there’s a brand new type of acne treatment that is currently in a phase 2 clinical trial.
