I had acne in my school days but I got them treated and they were cured but after 5years again I started having acne. In the starting it was one and two here but later it got worse black spots. The acne I get are not bigger in size but small bumps and sometimes get acne with pus filled in them. It doesn't pain but lives a mark/scar back. I also got my blood report checked the amount of neutrophils is 78%. Also I have a family history of acne. Also I have been using tremendous products like Serums vitc, niacinamide but they make my skin sensitive. What can be the cause?
