I have used a few other products with niacinamide and this one by far is the best one. I have oily skin and prone to breakouts and dark spots. I was interested in this product because it also had zinc in it. I had some existing pimples, specifically blackheads and existing dark spots. I have been using this product for at least a month and I love it. My blackheads have cleared up and the dark marks have faded. I recommend this product with those who have problematic skin.
