For me this didn't work. it's just not moisturizing enough and i believe it caused some mild irritation

another issue is the smell, there's something weird about some of cosrx products... I don't know why, but I feel like when i put them on my face it makes my skin smell like fish, even though the product doesn't smell nasty in the jar. keep in mind that i'm a very hygienic person and very sensitive to smell, but yeah, this smells like fish to me and i don't like it.
