Stargirl170 review for Niacinamide 10% + Zinc 1%

This is my favorite niacinamide serum that I have tried so far. This product has no smell and the texture is slightly thicker than water which I like. It spreads well on the skin and absorbs quickly without leaving a sticky residue. I used this product once a day to begin with but built up to using it twice a day. I am using this product to help regulate my oily skin and clear congestion which in the long run will help minimise breakouts and the size of my pores. I have been using this for several weeks and have noticed a difference in my skin (check out my before & after!) so will continue to use it!
