I've only been using the niacinamide powder for 10 days but it has made such a positive difference to my hormonal, excessively oily, acne-prone skin. So much so, I now use it in both the morning and evening.
Then I'm going outside or working by a window. I've noticed that my T-zone is less of an oil slick come 3pm and I have fewer blackheads.
