I bought this product because it gave me a perfect compatibility rating on Suzykirei. It's been about three weeks since I started using it (though it may have been compatible with other products), and when I had my skin checked at the cosmetics counter, I noticed a significant improvement, especially in the pores and texture. These two scores are almost perfect. Since I was about to run out of foundation, I had them match my color (a different product), and it brightened my skin by two tones. I haven't noticed any noticeable blemishes disappearing, but it seems to have worked for my skin. I use it after moisturizing my skin with lotion, but I take an appropriate amount and blend it all over my face. It feels sticky and absorbs into my skin, which I think is a sign that it's absorbed. If I don't blend it in enough, it feels like it will mix with the lotion I apply after. It doesn't feel particularly tingly, and I like that it's easily available at drugstores.
