This is best niacinamide I have ever tried. It is really expensive but it is very good

At first I was about 3.5 of 5 points, mostly because of the too small package that I almost broke it fell from the sink, that it is not the pump. But it is working with ALL my other serums and creams so well, it is helping with the hydration and hyperpigmentation and a bit with the pores as well. So the second bottle it is.

I love this product! My skin looks smoother and my pores smaller! I took off one star for the packaging. Sometimes the product leaks and crusts around the top of the applicator which just feels like a waste! I always have to make sure to close it extremely tight.

This serum is must have for oily skin. cant live without it

This bottle is super small, I have been using it for a week or so, and I haven't noticed difference between this and Sunday Riley B nice, that is 10% but bigger bottle, both have kinda sticky feeling that is nice for my oily skin with enlarged pores, they do help a bit little by little in combo with Vit C (my fave is Sunday Riley but I also did enjoy the one from Glow recipe). But I don't think 20% is for now making a big difference, so I unless I see it in a two month (I use it once a day bcs I have adapalene and AHA/BHA for the night, if you use it twice it probably wouldn't last this long), I won't be buying it again. It is nice but too small bottle for the price tag. I mean people can get Botox and various treatments that last 4 months or more for a bit double the price, some peels etc. It is just too much. The price tag of the skincare is gone wild.
