Review (4/5): Time will tell
I've been using this for only a few weeks. I don't notice drastic changes in my skin but then I don't think any product is a miracle product that will give me baby skin. Niacinamide is one of the best skin care ingredients you can apply. What it does do for me is help control sebum. My face doesn't get as oily, and I think over time, my pores will appear smaller. It can't shrink an existing pore, but if you're keeping the build up of sebum to a minimum, it can certainly keep them from getting larger, and less debris deep in the pores make them less noticable just by keeping the darker appearance down. It is a fast drying and tacky serum, I use a full pump all over and then apply my moisturizer over the top once it's dried down. Apply to the back of your hand and apply to one part of the face at a time. It can be hard to apply otherwise due to the tacky nature. As a side effect of sebum control, it has helped with the few spots I get. Though most of my breakouts are hormonal and I don't expect any one product to eradicate those, this has noticably helped lessen the amount of spots and the healing time is less. You can't go wrong for the price and the fact that there aren't any fillers, irritants, fragrances, or otherwise.
