Very disappointed with product. I’ve bought this multiple times before, so I thought nothing of immediately opening it and throwing away the packaging. This time there are chunks already in the applicator and it just feels like a waste of money.

I've used niacinamide for years since working in the dermatology field. I bought this because of the high concentration and have used it religiously. I'm very happy with the results. My skin is softer and slightly firmer. As a note, I wear sunblock under my makeup. This is recommended when using this product.

5.0 out of 5 stars Definitely works to minimize pores. I Did the Half face comparison after 30 days.
Reviewed in the United States on July 12, 2024
Verified Purchase
Each night for 30 days, I used my regular serum on one half of my face, and this product on the other.
I was pleasantly surprised at seeing smaller pores after 30 days using this serum. I used a magnifying glass and tilted my head up a bit. That angle really showed the difference in the size of my pores, in comparing the right side to the left. I have very oily skin and am almost 60. At that age pores also tend to sag on the face, which makes them look even larger. I would estimate they are at least 30% smaller now. I will definitely buy again when this runs out.
