Query: Made my skin worse :(

I was so excited about this product, I had read good reviews of it, and had read the studies about niacinamide and how it is a great topical anti-inflamitory making it great for rosacea. Well, it made my face redder and covered with tiny red dots. I then went to the rosacea sufferer's forum and read how for some rosaceans niacinamide works and the others it makes their rosacea worse, so I guess I fall into that last category :( I was so disappointed and saddened, I really thought from all I had read that I had finally found that magic potion for my rosacea, well, back to the drawing board. I do not blame the product, I think if you do not react to it it will work for you and this has a good amount in it with nothing you don't want, but just know that niacinamide is not for everyone and you never know if you might be one of the unlucky ones....
