Reviews about Anti-Dark Spot Serum with Vitamin C

I would like to leave a review about this serum. I bought it not here, but in Bulgaria. In my opinion, the texture is very sticky. It takes a long time for the skin to absorb it and leaves a sticky feeling on the face. Even in the morning, it feels like there is a film present on the face. I used it about five times, hoping that my skin would get used to it, but unfortunately, I ended up throwing it away.
