"43 year old with embarrassing blind pimples often turning to revolting whiteheads around chin area. first 2 weeks no clear improvement probably a little worse. existing pimples seemed to flare up with whiteheads. i don&#039;t know if it&#039;s all the bacteria finding a way out? its been 2 weeks &amp; finally seeing clearer skin. no whiteheads or blind pimples just purple spots that will hopefully heal.   no side effects at this point. taking one morning &amp; night."
