ANUA - SuzySY review for Niacinamide 10% + TXA 4% Dark Spot Correcting Serum

-Key Ingredients: Glycerin, Niacinamide(10%), Tranexamic Acid(4%), Arbutin(2%), Sodium Hyaluronate, Alpha-Arbutin, Various plant seed oil, Centella Asiatica Extract, Panthenol, Ceramide NP I was worried that a high concentration of niacinamide might irritate skin, so I introduced this serum to my skin slowly. I'm able to use it every day now . I don't have any problem using it with other activities in the same routine. It has a light-weight texture, but it’s a little sticky. Maybe I am applying too much. It's very very hydrating though. I think my hyperpigmentation & melasma is a little lighter since I start using it. I like this serum so far.
