I was wondering if epiduo can replace straight benzoyl peroxide...epiduo has 2.5% benzoyl peroxide and .1% adapalene. Quotejenaphile MemberMember1(@jenaphile) Posted : 01/20/2014 7:25 pm Just wondering why you'd want to replace it. BP is cheaper and OTC. Quote Aye Aye MemberMember122(@ayeaye) Posted : 01/21/2014 1:32 am I currently use Epiduo and used to follow the regimen using BP. They are very different products so if you're following the regimen then stick to using BP. Quote
