Retinol Cosmetic Recommendation_Innisfree Retinol Cica Blemish Ampoule

I'm concerned about my pores, so I squeeze out a pea-sized amount and apply it only to my butterfly zone and nose, and it seems to be surprisingly effective! I heard it can be irritating, so I don't use it every day; I just apply it occasionally, about 2 to 3 times a week.

And you know that you shouldn't apply retinol in the morning, right?
