Naturium - sandralisa review for Alpha Arbutin Essence 1%

I just started with this product a few days ago after getting it from a personal shopper. I really love the texture of the solution, very watery but doesnt leave any stickyness on the face after application. Despite containing citric acid, it doesnt irritate my sensitive skin (i apply in the morning and evening). I already can see some of my dark spot lighten.
