Even though I have a lot of black heads and white heads my pores are always quite small. I used this product several time before deciding that it's not for me though. There's a little tingling sensation when you rub it on your skin. After washing off the residue with a cleanser I saw some white heads poking out so I hoped that it was working. However, I'm so so sure... There is one thing though, my pores got larger even though I did rinse my face with cold water after washing and my nose appeared a little red like there's skin irritation. It's been two days and I don't think the large pores and redness is gonna go away. I've always liked Innisfree but I don't think this product is for me....
