I previously purchased a small trial bottle from the official Shiseido website and liked the feel, so I purchased this on the 1st from the Suzykirei website. It feels like it penetrates into my face thoroughly. I love it. It's not yet the sunny season, so I'm looking forward to seeing if my dark spots increase in spring and summer. I'll buy a refill when it runs out. Until now, I've been using Menard's Fairlucent whitening serum morning and night for many years, but I feel like my skin has gotten used to it, or maybe my dark spots are increasing... I'd like to stick with this whitening serum for a while.
