REVIEW: Porebright N10 Serum (Facetheory) Niacinamide, also called vitamin B3, is a real skin hero for every skin type! With regular use, this product would provide smoother and more radiant skin. Other benefits can be read at: https://www.dr-jetskeultee.nl/niacinamide/. Before I had Facetheory serum at home, I used The Ordinary niacinamide serum for a while. With this serum, I actually got more radiant skin, so I'm also very curious about the Facetheory serum. Both products contain only ingredients that are good for the skin. First impression: With The Ordinary serum, the packaging was a little disappointing to me. The cap didn't go well and there was always a bit of the product on the sides, so I had to take it off regularly with a cotton pad. I was pleasantly surprised at the Facetheory game. The opening of the jar is narrowed, so the product does not leak and reduces oxygen. Finally, it's a less solid substance than The Ordinary serum and requires less of the product to lubricate your face well. I'm going to use the product for a while now and let you know if the product is worth ordering! (Product is not yet on We Are Eves and have requested).
