I was very hesitant to try this product as I find most moisturizers break me out. I have very sensitive, oily, acne prone skin and this caused no irritation. However, I find, that for my oily skin, it is a bit heavy for morning use.

I have not noticed a change in pore size nor reduction in blackheads, but, to be honest, my pores are quite small and I rarely get blackheads ever since using the COSRX BHA Blackhead Power Liquid. The fact that this product does not make my skin worse is the main reason I love and will continue to use this moisturizer. Overall, I find COSRX to provide some of the best skin care products.
