Up to 2 months: Acne can be a very frustrating condition. Most over the counter and prescription medications don't work to clear up the spots you have. They start working from day 1 to prevent new pimples. However, it can take up to 8 weeks for pimples to form, and some under the surface of your skin may still pop up in that 8 week period. Be patient! don't stop your acne medications and you will see results.

Unclear question: Is the benzoyl peroxide making your face red or do you have red marks from old pimples. If the red marks from the old pimples are what you are talking abou, they will fade with time. If your whole face is red from benzyl peroxide you may be using too strong a strength or it is possible that you cannot tolerate it at all. This is true for some patients.
