Innisfree Retinol Cica Ampoule

I bought this Cica ampoule because people said it was good. I bought it because they said it's good for exfoliation and pores, but hmm, honestly, I don't really notice any effect. It doesn't feel super moisturizing after applying it, and even after using it for a month, I don't really feel like it's helping my pores yet. Since I have dry skin, I prefer that moisturizing feeling after application, but I think it would be fine for people with oily skin. It adheres really well to the skin after application. If you like serums that aren't too oily, I think it wouldn't be a bad idea to try it out once when it's on sale.
