Anua 10% Niacinamide + 4% TXA Dark Spot Correcting Serum

I find this serum to be good with glow of the skin , as for the dark spot I have not seen any improvement , most likely due to my old age , however it does seems to tighten the skin after application , good product , thank you .

I super love this product. My skin looks healthier and I'm even -toned.

Amazing product
