Hello. So I stumbled upon this site earlier today and read through the Regimen, intrigued I rushed to the store and got the products that were recommended. The only snag however, was that there is seemingly no 2.5% benzoyl peroxide in any drug stores near my area. I first stopped off at a drug store that had the right moisturizer and cleanser, but only 5% benzoyl peroxide. The pharmacist there even went as far as to see if he could order some 2.5% for me for the following morning -- he couldn't, apparently they don't even stock it.
I then went to two different locations and called another two in the area, none of them had 2.5%, only 5% which I ended up purchasing. My question is, how important is 2.5% when compared to 5%? I can't seem to easily get my hands on it and I really want to start this "Regimen" as soon as possible, as my cystic acne seems to be only getting worse by the day, however I'm worried that a simple difference like this will only end up making it worse in the end.
