I really liked the idea of this product...use the little brush and apply the powder to your blemish.  That part worked out fine.  So the problem came up about a week after I started using it.  When it arrived I read the packaging as I always do and checked the ingredients carefully.  There was one ingredient listed "Algae Extract" that I was worried about.  I had used a product with this ingredient about 4 years ago and my skin brokeout horribly in the biggest whiteheads I'd ever had but I was never sure that algae extract was the culprit.  Well, I knew it was the culprit a week after I started using this.  Every area I had applied this on my face was now covered in deep, painful zits.  Big zits, not little ones.  It took a trip to the face lady for a peel and about a week and a half to start looking better.  I now know algae extract and my skin do not mix well.  It just seemed so strange to me that a product called Blemish Therapy would include an ingredient with a comedogenic rating of 5 which is the worst rating an ingredient can get.
