Hey, I get a lot of comments and DM regarding skin pores issue, redness, and oily skin, and I always recommend this serum. So here is a proper review of my favorite The Ordinary Niacinamide Serum for oily and acne-prone skin. I finished the first bottle and genuinely loved it. I hope this information will be helpful to you. Also. I bought all the ordinary products from my own money so it's not a sponsered video.
