    Not for me

    Personally I didn't feel that this did anything for me. I tried it to try and tackle excess oil since I was wearing makeup every day to the office. It could just have been the combo of this with the makeup I was wearing or maybe my whole skin routine wasn't blending well together. But I didn't see much of a difference with this one as I do with other products. I personally would not buy again.

    Good serum, not sticky

    This serum is not sticky like all other niacinamide serums I tried. I guess it works well. It´s not though totally matt for use under makeup for oily skin.
