Glamfam, I got the Laneige Water Sleeping Mask a few months ago and wanted to share my thoughts as someone with acne prone skin. I am a big fan of KBeauty and Laneige products in general so I was pretty stoked to get my hands on the Water Sleeping Mask.
My biggest impression after using this product is HYDRATION. They don't call it the Water Sleeping Mask for nothing. I normally have pretty dry skin and by the end of the day if I look closely in the mirror I see little flakes on my cheeks (ew, I know). But after using this product on the regular I've definitely been noticing less flaking. I have not noticed super drastic differences in my acne but my face is a little less red.
Overall, if your look for a good moisturizing product, this is the one.
