This is a whitening cream that moisturizes well! It's more moisturizing than advertised, so I use it every few days. It does seem to remove some of the dullness that's a winter enemy!
The container is luxurious, sparkly, and cute. However, fingerprints are very visible, and the container is large for the amount of cream it contains, so it takes up a lot of space. It feels quite sticky when you use it, but it gets a little better after a while. I think this is a matter of personal preference, but I prefer it to be less sticky. However, it does leave my skin feeling bouncy. It may have moisturizing properties, but as I have dry skin, it was a little dry in the morning. I have sensitive skin, but I didn't notice any irritation. I would recommend it to anyone looking for a whitening cream.
I've been interested in this product for a while, and it came as a supplement in a magazine. My impressions after using it were neither good nor bad. I haven't noticed any particular changes to my skin. It doesn't dry out my skin, but it does moisturize well.
I also received this as a gift along with the serum. It's a dry season, but it feels like it locks in moisture. The container is also beautiful, which makes me excited when I'm doing my skincare routine. I hope to continue using it for a while and get closer to dewy, glowing skin. It's not sticky, and I like the texture, so I'd like to continue using it for a while.
