Anua Niacinamide 10% + TXA 4% Serum

Great serum

The serum works well. My skin is firmer, so the fine lines are less apparent. It did equilibrate my skin complexion, even if this wasn't my major concern. After three days, my pores shrank. It doesn't smell good or bad, and the colour is really pretty and aesthetically pleasing on a shelf. The downside is that it is sticky for a long time, so if you want to moisturize (it's recommended after applying a serum I think) then you have to wait.
