I've been using the acne.org bp since June of 2016. The regimen worked great for my skin, and since then I've repurchased from the company 3 times. I bought another bottle of bp, but every time I use it it doesn't fully absorb no matter how long I wait after I wash my face/ before putting on moisturizer. It clumps up when I try to rub and sometimes pat it into the skin and leaves a white residue. I'm wondering is it because of the temperature changes in my room? Sometimes it's really warm and sometimes it's cold. This has never happened with any of my other bottles. Have the ingredients changed? I'm not sure. I've tried several different methods of using the bp but I get the same results every time. Anyone that can relate? Advice? Inserted some before and after a throughout the months as well
