COSRX The Vitamin C 23 Serum, bought with my own money

I have combination skin that is prone to dehydration, and lately my skin tone seems to be getting redder, so I am quite interested in brightening. First of all, I liked that the COSRX The Vitamin C 23 Serum comes in a dropper type. It allows for easy control of the amount and feels hygienic, haha. It looks like a thick, yellow texture, but I liked that it absorbed very moisturizingly into the skin. It has a firm, bouncy feel, but it isn't unpleasantly sticky, so I think people with oily skin will definitely like it as well. I have been using it for over a week now, and I am satisfied with the application and overall feel.

I want to keep using this and see if it helps with my skin tone and brightening. I find myself wanting to buy more when there is an Olive Young sale haha.
