I bought this serum on my trip to Seoul, and really liked it. I'm lazy to store vitamin c at fridge, so this serum is more convenient to just have it in my bathroom. I also think it helps with my acne scars, although it will probably take a few more bottled to completely clear it. The texture is lightweight and it's good for combo skin like mine, but I definitely need to use a moisturizing ampoule and cream since it's cold winter now in my country.
