I ordered this serum after using it from a sample that I received with a previous order. It definitely helped me with the redness in my cheeks and gives me a nice hydrated glow. I use this along with COSRX’s HA Intensive cream for my face prep before putting on makeup. I do like the product itself but the only issue I have is that the serum bottle dropper came broken and doesn’t pick up or dispense any of the product so I have to tap it out.
