So I went ahead and ordered these when Jolse was having their Wish Formula 1+1 sale! I really didn't know what to expect from these since at the time no one reviewed them but since they were on sale anyways I went ahead and tried them. I used them after exfoliating with the C200 bubbling pads. After applying it did leave my face feeling sticky and kinda uncomfortable since I wasn't used to vitamin c serums and it was like that for I would say 30ish minutes. BUT lemme just say after this product becomes fully absorbed, it leaves your face feeling oh so soft, smooth, and refreshed!!!
