Calys - Sugars review for Niacinamide Dark Spot Serum

This serum has a thick texture. The scent almost unscented. I think its lightweight & fast absorb, but kinda a bit sticky. After 2 weeks tried this serum, its quite good for brightening & faded any dark spot, but not enough for me because i already try higher percentage. But despite of that this serum quite good. And i think this serum suitable who wanna try niacinamide for the first time. And its suitable for all skin type especially sensitive skin.
