Paula's ChoiceCLINICAL 20% Niacinamide Vitamin B3 Concentrated Face Serum, Anti-Aging Serum for Face, Treatment for Discoloration & Minimizing Large Pores, Fragrance-Free, 0.67oz

I really do like this Niacinimide solution. There are complaints about dried up solution in the dropper. That is normal if niacinimide has not be used and is exposed to air like that. My dropper had a dried amount. I simply pulled the dropper of and rinsed it in hot water. The dried product came out and dropper was able to dispense again. The solution in the bottle was perfectly fine. This product is very good at keeping your pores clean. Highly recommend it.

Works really well. Noticeable difference. Expensive for the volume but worth it.

Love love love this product. Skin looks poreless after use and a greta foundation for makeup.

I was expecting better result but it don’t seem to have had much impact on my skin.

Me ayuda mucho con las manchas y te ayuda a cerrar los poros

I love that this product has no fragrance. Also, since using it my pores are noticeably smaller and I have less breakouts than I used to. It also seems to make my skin feel smoother overall. I really like it and will order again.

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.
