Hello, I'm 22 and am currently using the three step Acne Free product line and I am pleased with the results. However, I only use step one (face wash) and step three (benzoyl peroxide cream). As far as I know, I cannot buy step three of the Acne Free product line by itself so I was wondering if anyone can suggest a BP cream similar to that of Acne Free that I can use when I run out of step 3. Step 3 has 3.7% BP and I have no sort of irritation or reaction. Thank you.
