To be honest, Cosrx is my all time favorite skincare brand, and I have yet to find something I don't like. I have combination-oily skin, and I find that a drop of this ampoule at night really helps to moisturize and nourish my skin. I don't use it in the morning, as it does make the skin slightly shiny (not something I need due to my oily skin). AT night though, I love adding this in as a final moisturizing step to really ensure my skin is set for the night. After sing this for a week, I have noticed a difference in how soft my skin feels, as well as how moisturized it feels during the day. Will repurchase, and I highly recommend.
