I bought this to use with the cosrx propolis toner and I love it! It soothes my sensitive skin and acne, whilst hydrating my dry skin. This has lasted me a lot longer than I thought it would (almost three months) when other cheaper ampoules only lasted me two weeks. Before using these two products my skin was dry, sensitive with bad acne. I still get acne but its so much better than before, and clears up within a couple of days, rather than over a week like before. I recommend this dream team of products!
