After trying out History of Whoo Seol Whitening line (I've separated my review for the CC Sun Cream from the same line here), I switched to try out its biggest competititor, Sulwhasoo Snowise EX Whitening Line. I used it for a month. Reading reviews, I've heard better things from History of Whoo, but personally I've had better success with Sulwhasoo products so I still wanted to give it a try. Last year I experimented with my own made up combination of Hadalabo Shirojyun Whitening Essence and The Saem Chaga White Liposome Biocellulose Sheet, which worked, but I'm always into trying new products, especially whitening products. Give me my white pearly skin!
I actually tried out the Sulwhasoo Snowise EX Whitening Eye Treatment first before I tried the rest of the line so I've posted a separate review of that here.
