I’m surprised this serum wasn’t more popular than it is. I bought this based off of Alice in the rabbit holes YouTube video about the Numbuzin brand. She ranted about the cica 8 serum and the no. 2 cica ceramide moisturizer and I definitely agree! Layering the 2 definitely soothed and hydrated my skin. It’s cool because it can be used as a serum or a moisturizer which I’ve never seen before!
