First thing is that I am not allergy to it LOL. I’m very very glad because my face is so sensitive. Any skincare product I try always brings rashes, but I am not allergic to this serum, Yeah. After applying on my face, it does not leave a sticky feeling and the scent is nice. Its texture is light and easily absorbed. I feel my face is smoother when waking up in the morning. After using it for a while, my face becomes brighter. I cannot explain more, but I feel very happy.
